Cisco IOS Release 12.1(3)T supports the Cisco 7000 family:
For detailed descriptions of the new hardware features, see "New and Changed Information" section.
|
Note A Hardware-Software Compatibility Matrix is available on CCO for users with CCO login accounts. Using this matrix allows you can search for supported hardware components by entering a Cisco platform and IOS Release. The Hardware-Software Compatibility Matrix tool is also available at the following URL: http://www.cisco.com/cgi-bin/front.x/Support/HWSWmatrix/hwswmatrix.cgi |
To determine the version of Cisco IOS software running on your Cisco 7000 family router, log in to the router and enter the show version EXEC command:
router> show version Cisco Internetwork Operating System Software IOS (tm) 12.1 T Software (C7200-JS-MZ), Version 12.1(3) T, RELEASE SOFTWARE
For general information about upgrading to a new software release, see Upgrading the Cisco IOS Software Release in Cisco Routers and Modems located at:
http://www.cisco.com/warp/public/620/6.html
Microcode software images are bundled with the system software image—with the exception of the Channel Interface Processor (CIP) microcode (all system software images). Bundling eliminates the need to store separate microcode images. When the router starts, the system software unpacks the microcode software bundle and loads the proper software on all the interface processor boards. Table 2 lists the current microcode versions for the Cisco 7000 family.
| Processor or Module | Current Bundled RSP Microcode Version | Minimum Version Required |
|---|---|---|
AIP (ATM Interface Processor) | 20.18 | 20.13 |
EIP (Ethernet Interface Processor) | 20.6 | 20.3 |
FEIP (Fast Ethernet Interface Processor) | 20.8 | 20.7 |
FIP (FDDI Interface Processor) | 20.4 | 20.4 |
FSIP (Fast Serial Interface Processor) | 20.9 | 20.9 |
HIP (HIIS Interface Processor) | 20.2 | 20.2 |
MIP (MultiChannel Interface Processor) | 22.3 | 22.3 |
TRIP (Token Ring Interface Processor) | 20.2 | 20.2 |
VIP2 (second-generation Versatile Interface Processor) | 22.20 | 22.20 |
The Cisco IOS software is packaged in feature sets consisting of software images—depending on the platform. Each feature set contains a specific set of Cisco IOS features.
Release 12.1 T supports the same feature sets as Release 12.1, but Release 12.1 T can include new features supported by the Cisco 7000 family.
 |
Caution Cisco IOS images with strong encryption (including, but not limited to 168-bit (3DES) data encryption feature sets) are subject to United States government export controls and have limited distribution. Strong encryption images to be installed outside the United States are likely to require an export license. Customer orders may be denied or subject to delay due to United States government regulations. When applicable, purchaser/user must obtain local import and use authorizations for all encryption strengths. Please contact your sales representative or distributor for more information, or send an e-mail to export@cisco.com. |

The Bridging Between IEEE 802.1Q vLANs feature provides the ability to connect a network of hosts over a simple bridging-access device to a remote access concentrator. This feature supports the following IEEE 802.1Q (dot1q) functionality:
This feature enables interoperability and compatibility between dot1q encapsulated interfaces and all supported interface medias, such as Inter-Switch Link (ISL) encapsulated interfaces. The packets on the dot1q link contain a standard Ethernet or Fast Ethernet frame and the VLAN information associated with that frame. To interoperate with existing Cisco routers, run spanning tree per-VLAN over ISL or PVST, where a single spanning tree caters to every VLAN in the domain, PVST+ runs spanning tree on a per VLAN basis, and a default VLAN 1 spanning tree (also called Common Spanning Tree) tunnels to the IEEE 802.1Q specific VLAN.
Platforms: Cisco 7200 series and Cisco 7500 series routers
Beginning with this release, Cisco Express Forwarding (CEF) is supported on interfaces on which IEEE 802.1Q encapsulation has been enabled at the subinterface level. You no longer have to disable CEF operation on interfaces that are using IEEE 802.1Q encapsulation on VLAN subinterfaces.

The Circuit Interface Identification MIB feature adds support for a new Cisco enterprise MIB, used to assist in SNMP monitoring of circuit-based interfaces. The Circuit Interface MIB (CISCO-CIRCUIT-INTERFACE-MIB) provides a MIB object, which can be used to identify individual circuit-based interfaces (for example, interfaces using ATM or Frame-Relay). This user-specified identification is then returned when linkup and linkdown SNMP traps are generated for the interface.
The Circuit Interface MIB consists of a single table, with each row comprising a sequence of two objects: circuit interface description (cciDescr) and circuit interface status (cciStatus). The cciDescr object is used to identify circuits using a textual description of up to 255 characters specified by the user (note that MIB objects are modified using network management system applications, and cannot be configured using the Cisco IOS command-line interface). When the row is created by a user, a value is set for the cciDescr object. The table is indexed by ifIndex from the IF-MIB. The cciStatus is the RowStatus object for the rows in the table. The cciStatus object can be set to only two values by the user: createAndGo(4), which creates a new row, and destroy(6), which removes an existing row. If the row is created successfully, the cciStatus is active(1). When creating a new row, set the cciDescr object along with the cciStatus in a single snmp set pdu command. If the row is already active, only the cciDescr object can be modified. The other option is to delete the row first by setting the cciStatus to destroy(6), and then recreate the row with a new value for cciDescr. When creating a new row, the ifIndex is validated first. If the ifIndex value is not valid, the row is not created and an error code is returned. Similarly, if, when an interface is deleted, there was a corresponding row in this table, that row is deleted automatically.
After an identifying description is created for an interface by a user, the description (the cciDescr object) is sent along with the other varbinds as part of linkup and linkdown trap notifications.

The Class-Based Packet Marking feature provides users with a user-friendly command-line interface for efficient packet marking by which users can differentiate packets by designating them different identifying values. The Class-Based Packet Marking feature allows users to perform the following tasks:
After setting the IP precedence bits or the IP DSCP, a user can classify a packet based on the IP precedence bit or IP DSCP value. These classifications are then used to apply user-defined differentiated QoS services to the packet.
Associating a packet with a local QoS group allows users to associate a group ID with a packet. The group ID can be used to classify packets into QoS groups based on prefix, autonomous system, and community string.
A user can set up to 8 IP precedence markings, 64 IP DSCP markings, and 100 QoS group markings.

Class-based tr affic shaping allows you to control the traffic that leaves an interface in order to match its transmission to the speed of the remote, target interface and to ensure that the traffic conforms to policies contracted for it. Traffic adhering to a particular profile can be shaped to meet downstream requirements, thereby eliminating bottlenecks in topologies with data-rate mismatches.
Using the Class-Based Shaping feature, you can do the following:

The Event MIB is an asynchronous notification mechanism standardized for use by network management systems using Simple Network Management Protocol (SNMP).
The Event MIB provides the ability to monitor the Cisco Management Information Base (MIB) objects on the local or remote system using SNMP and take simple action whenever a trigger condition is met. By allowing notifications based on events, the Network Management Server does not need to constantly poll managed devices to find out if something has changed.
Support of the Event MIB has been added to Cisco IOS software to work with existing network management systems and, when combined with the currently integrated Expression MIB support, provides a flexible and efficient way to monitor complex conditions on network devices. By allowing SNMP notifications to take place only when a specified condition occurs, Event MIB support reduces the load on affected devices, significantly improving the scalability of network management solutions.
Platforms: Cisco 7100 series and Cisco 7200 series routers
This feature adds support of the Delta, Wildcarding, and Aggregation features in the Distributed Management Expression MIB (EXPRESSION-MIB) to Cisco IOS software for use by SNMP.
The Delta function enables the Expression MIB to use Delta values of an object instead of absolute values when evaluating an expression. Delta is obtained by taking the difference between the current value of an object and its previous value.
The Wildcarding function of the Expression MIB allows evaluation of multiple instances of an object. This is useful in cases when an expression needs to be applied to all instances of an object. You do not need not individually specify all instances of an object in the expression. Rather, you only need to set the expWildcardedObject in expObjectTable to TRUE for the respective object.
Aggregation is performed using the sum function in the Expression MIB. The operand to the sum function must be a wildcarded object. The result of the sum function is the sum of values of all instances of the wildcarded object.
For a complete description of Expression MIB functionality, see the Distributed Management Expression MIB Internet-Draft document, available through the ITEF at http://www.ietf.org/ids.by.wg/disman.html.

The Frame Relay ELMI Address Registration feature enables a network management system (NMS) to detect connectivity among the switches and routers in a network using the Enhanced Local Management Interface (ELMI) protocol. During ELMI version negotiation, neighboring devices exchange their management IP addresses and ifIndex. The NMS polls the devices to collect this connectivity information.
Before this feature was introduced, NMSs could detect only the topology of routers or the topology of switches. This feature enables the NMS to detect switch and router interconnection and create an end-to-end network topology map for network administrators.
The Cisco Frame Relay MIB has been enhanced to support the new ELMI information. The NMS uses the MIB to extract the IP address and ifIndex of devices neighboring the managed device.

Note General Packet Radio Service (GPRS) Release 1.4 is a specially licensed feature that is available only through a controlled image release in Cisco IOS Release 12.1(3)T. GPRS Release 1.4 is the recommended upgrade for both GPRS Release 1.2 (available in Cisco IOS Release 12.1(1)GA) and GPRS Release 1.3 (available in Cisco IOS Release 12.1(2)GB). For more information about acquiring GPRS Release 1.4, please contact your Cisco sales representative. Customer documentation for GPRS Release 1.4 is available on CCO and the documentation CD-ROM. |
General Packet Radio Service (GPRS) is defined and standardized by the European standards body ETSI. GPRS is an IP packet-based data service for GSM networks. The GPRS network essentially consists of two major elements, the serving GPRS support node (SGSN) and gateway GPRS support node (GGSN).
The GGSN is a wireless gateway that allows mobile cellular phone users to access the public data network (PDN) or specified private IP networks. User sessions are connected from a mobile station through a device called a Base Station Subsystem (BSS) and then to a Serving GPRS Service Node (SGSN).
The connection between the SGSN and the GGSN is enabled through a protocol called the GPRS Tunneling Protocol (GTP). Finally, the connection between the GGSN and the PDN is enabled through the Internet Protocol (IP).
In order to assign mobile user sessions an IP address, the GGSN uses the Dynamic Host Configuration Protocol (DHCP). To authorize and authenticate the remote users, the GGSN can use a RADIUS server. DHCP and RADIUS services can be specified for the global configuration, using GPRS DHCP and RADIUS commands, or for each access point configured for the GGSN.

The HSRP Support for Internet Control Message Protocol (ICMP) Redirects feature enables Internet Control Message Protocol (ICMP) redirection on interfaces configured with the Hot Standby Router Protocol (HSRP).
When running HSRP, it is important to prevent hosts from discovering the interface (or real) MAC addresses of routers in the HSRP group. If a host is redirected by ICMP to the real MAC address of a router, and that router later fails, then packets from the host are lost. Previously, ICMP redirect messages were automatically disabled on interfaces configured with HSRP.
This feature now enables ICMP redirects on interfaces configured with HSRP. This functionality filters outgoing ICMP redirect messages through HSRP, where the next-hop IP address may be changed to an HSRP virtual IP address.
Platforms: Cisco 7200 series and Cisco 7500 series routers
The HSRP support for Multiprotocol Label Switching (MPLS) VPNs feature enables ICMP redirection on interfaces configured with the Hot Standby Router Protocol (HSRP).
The Internet Control Message Protocol (ICMP) is a network layer Internet protocol that provides message packets to report errors and other information relevant to IP processing. ICMP provides many diagnostic functions and can send and redirect error packets to hosts.
HSRP provides network redundancy in a way that ensures that user traffic immediately and transparently recovers from first-hop failures in network edge devices and access circuits. By sharing an IP address and a MAC (Layer 2) address, two or more routers can act as a single virtual router to the hosts on a LAN. The members of the router group continually exchange status messages by detecting when a router goes down. This HSRP group consists of an active router and a standby router to replace the active router should it fail. The address of this HSRP group is referred to as the "virtual ip address."
When running HSRP, it is important to prevent the host from discovering the primary MAC addresses in its standby group. If a host is redirected by ICMP to a standby group that later fails, the packets are lost. Previously, ICMP redirect messages were disabled on interfaces configured with HSRP. This was done to avoid the host from being directed away from the virtual IP address (the HSRP group address that provides redundancy) to the interface IP and MAC address of a single router. If this single router failed, redundancy was lost.
The HSRP Support for the ICMP Redirect Messages feature now enables ICMP redirects on interfaces configured with HSRP. This feature works by filtering outgoing ICMP redirect messages through HSRP, where the next-hop IP address is changed to an HSRP virtual IP address.

Multiprotocol Label Switching (MPLS) traffic engineering software enables an MPLS backbone to replicate and expand upon the traffic engineering capabilities of Layer 2 ATM and Frame Relay networks. MPLS is an integration of Layer 2 and Layer 3 technologies. By making traditional Layer 2 features available to Layer 3, MPLS enables traffic engineering.
Traffic engineering is essential for service provider and Internet service provider (ISP) backbones. Such backbones must support a high use of transmission capacity, and the networks must be very resilient so that they can withstand link or node failures.

As DSL deployment continues to grow, ATM PVC provisioning becomes extremely cumbersome. Network Access Providers (NAPs) must nail up each PVC between subscriber and NAP. Terminating point and quality of service of PVCs are predetermined and provisioned. With the PPP over ATM Switched Virtual Circuit (SVC) support feature you can choose services and the quality of those services based upon ATM address. When an end user initiates a connection to a service, an ATM SVC is set up with a desired destination using a configured ATM address. After the ATM SVC is set up, a PPP session is established on the ATM SVC. NAPs or Network Service Providers (NSPs) can use PPP over ATM to authenticate and authorize users to use its services.
End users can run PPP over ATM SVC on Win98/2000 on a PC with an asymmetric digital subscriber line (ADSL) Network Interface card (NIC) attached to a DSL or an ATM25 card attached to an ATM25 LAN connected to an ADSL remote office (ATU-R). PPP sessions may terminate at the NAP or tunneled to an NSP.
PPP over ATM SVC supports the following functions:

RSVP is a network-control protocol that provides a means for reserving network resources—primarily bandwidth—to guarantee that applications transmitting end-to-end across networks achieve the desired quality of service (QoS).
RSVP enables real-time traffic (which includes voice flows) to reserve resources necessary for low latency and bandwidth guarantees.
Voice traffic has stringent delay and jitter requirements. It must have very low delay and minimal jitter per hop to avoid degradation of end-to-end QoS. This calls for an efficient queuing implementation that can service voice traffic at almost strict priority in order to minimize delay and jitter.
RSVP uses weighted fair queuing (WFQ) to provide fairness among flows and to assign a low weight to a packet to attain priority. However, the preferential treatment provided by RSVP is insufficient to minimize the jitter because of the nature of the queuing algorithm itself. As a result, the low latency and jitter requirements of voice flows might not be met in the prior implementation of RSVP and WFQ.
RSVP provides admission control. However, to provide the bandwidth and delay guarantees for voice traffic and get admission control, RSVP must work with LLQ. The RSVP support for LLQ feature allows RSVP to classify voice flows and queue them into the priority queue within the LLQ system while simultaneously providing reservations for nonvoice flows by getting a reserved queue.

Secure Shell (SSH) is a protocol that provides a secure, remote connection to another router. There are currently two versions of SSH available, SSH Version 1 and SSH Version 2. Only SSH Version 1 is implemented in Cisco IOS.
The Secure Shell Version 1 Integrated Client feature is an application that runs on a reliable transport layer, such as TCP/IP, and provides strong authentication and encryption. The SSH client enables a Cisco router to make a secure, encrypted connection to another Cisco router or device running an SSH Version 1 server. This connection provides functionality that is similar to an outbound Telnet connection except that the connection is encrypted. With authentication and encryption, the SSH client provides a secure communication over an insecure network.
The SSH client in Cisco IOS works with publicly and commercially available SSH servers.The SSH client supports DES (56-bit) and Triple DES (168-bit) encryption using random number generation.
The SSH client also supports user ID and password authentication using standard authentication methods: local authentication, RADIUS, and TACACS+.
The SSH Version 1 Integrated Client feature uses the RSA algorithm to generate key pairs for authentication.

The Source Specific Multicast (SSM) feature is an extension of IP multicast, where datagram traffic is forwarded to receivers from only those multicast sources to which the receivers have explicitly joined. When SSM is used, only source-specific multicast distribution trees (no shared trees) are created.
Source specific multicast (SSM) is a datagram delivery model that best supports one-to-many applications, also known as broadcast applications. SSM is the core networking technology for the implementation of Cisco solutions targeted for audio and video broadcast application environments.

Transparent CCS allows the connection of two PBXs with digital interfaces that use a proprietary or unsupported CCS protocol without the need for interpretation of CCS signaling for call processing. T1/E1 traffic is transported transparently through the data network and the feature preserves proprietary signaling. From the PBX standpoint, this is accomplished through a point-to-point connection. Calls from the PBXs are not routed, but follow a preconfigured route to the destination.

The Virtual Switch Interface Master MIB provides a standardized vehicle for monitoring the operation of the VSI protocol within a Label Switch Controller (LSC). It also displays the results of the protocol operations. Specifically, with the VSI Master MIB you can monitor:
With the VSI Master MIB you can enlist Simple Network Management Protocol (SNMP) to monitor the status of the VSI protocol and the results of its operations.
This MIB is primarily oriented toward management of Multiprotocol Label Switching (MPLS) systems. As such, the MIB resides in routers that are also LSCs. These are routers that are VSI capable, and whose network control application is MPLS.

The WCCP Redirection on Inbound Interfaces feature adds support to Cisco IOS software for the redirection of Web Cache Coordination Protocol Version 2 (WCCPv2) traffic on inbound interfaces. Prior to this release, WCCP was implemented as an output feature only, with packets classified by WCCP after a routing table lookup. With Cisco IOS release 12.1(3)T, you can now configure an interface for inbound redirection using CEF, dCEF, fast forwarding, and process forwarding paths. WCCP redirection on inbound interfaces avoids the processing overhead created by CEF on outbound interfaces.
The following new hardware features are supported by the Cisco 7000 family for Cisco IOS Release 12.1(3)T:
Platforms: Cisco 7200 series and Cisco 7500 series routers
The PA-VXB and the PA-VXC are multichannel packet voice port adapters that allow Cisco 7200 series, Cisco 7200 VXR, and Cisco 7500 series routers to become dedicated packet voice hubs or packet voice gateways that connect to both private branch exchanges (PBXs) and the Public Switched Telephone Network (PSTN). This allows packet voice and packet fax calls to be placed over the wide-area network (WAN) and sent through the gateway into the traditional circuit-switched voice infrastructure.
The PA-VXB and the PA-VXC are single-width port adapters with two universal ports that are configurable for either T1 or E1 connection. The PA-VXB contains 12 high-performance digital signal processors (DSPs) that support up to 48 medium-complexity or 24 high-complexity channels of compressed voice. The PA-VXC contains 30 high-performance DSPs that support up to 60 medium-complexity or 120 high-complexity channels of compressed voice.
In Voice over IP, the DSP segments the voice signal into frames, which are then coupled in groups of two and stored in voice packets. These voice packets are transported using IP in compliance with ITU-T specification H.323. Because Voice over IP is a delay-sensitive application, you must have a well-engineered network end-to-end to use it successfully. Fine-tuning your network to adequately support Voice over IP involves a series of protocols and features geared toward quality of service (QoS). Traffic shaping considerations must be taken into account to ensure the reliability of the voice connection.

The AAA Server Group Deadtimer feature allows each authentication, authorization, and accounting (AAA) server to be fully configured in the server group. Thus, you can direct AAA traffic to separate groups of servers that have different operational characteristics.
With the introduction of this feature, deadtime has been added as a new attribute to the server group structure. In addition, a separate timer has been attached to each server host in every server group. Therefore, when a server is found to be unresponsive after numerous retransmissions and time-outs, the server is assumed to be dead. The timers attached to each server host in all server groups are triggered. In essence, the timers are checked and subsequent requests to a server (once it is assumed dead) are directed to alternate timers, if configured. When the network access server receives a reply from the server, it checks and stops all configured timers (if running) for that server in all server groups.
If the timer has expired, only the server to which the timer is attached is assumed to be alive. This becomes the only server that can be tried for later AAA requests using the server groups to which the timer belongs.

Bidirectional PIM (bidir-PIM) is a variant of the Protocol Independent Multicast (PIM) suite of routing protocols for IP multicast. Bidir-PIM is derived from the mechanisms of Protocol Independent Multicast sparse mode (PIM SM) and shares many of its protocol elements. In short, bidir-PIM is PIM SM with shared tree, but no shortest path tree operations. Bidir-PIM also has unconditional forwarding of source traffic toward the Route Processor (RP) upstream on the shared tree, but no registering process for sources as in PIM SM. These modifications are necessary and sufficient to allow forwarding of traffic in all routers solely based on the (*, G) multicast routing entries. This feature eliminates any source-specific state and allows scaling capability to an arbitrary number of sources.

With the Configurable Timers in H.225 feature you can configure the H.255 TCP connection timeout value for all out-going call attempts (on a per VoIP dial-peer basis).
In previous releases of the Cisco IOS software, the call attempt timeout was 15 seconds and could not be changed. In some cases, however, users might need a shorter timeout value to facilitate a faster failover. In other cases, users might need a greater timeout value.
The Configurable Timers in H.225 feature addresses those needs by providing the ability to override the default of 15 seconds and to configure the timeout value.

The Ecosystem Gatekeeper Interoperability Enhancements, Phase 2 feature supplements the existing support for alternate gatekeepers and adds support for the alternate gatekeeper field (altGKInfo) to the admission rejection (ARJ). This allows a gateway to move between gatekeepers during the admission request (ARQ) phase.
Platforms: Cisco 7200 series and Cisco 7500 series routers
The Frame Relay PVC Interface Priority Queueing (FR PIPQ) feature provides an interface-level priority queueing scheme in which prioritization is based on destination PVC rather than packet contents. For example, with FR PIPQ you can configure a PVC transporting voice traffic to have absolute priority over a PVC transporting signalling traffic, and a PVC transporting signalling traffic to have absolute priority over a PVC transporting data.
FR PIPQ provides four levels of priority: high, medium, normal, and low. The Frame Relay packet is examined at the interface for the data-link connection identifier (DLCI) value. The packet is then sent to the correct priority queue based on the priority level configured for that DLCI.
Platforms: Cisco 7200 series and Cisco 7500 series routers
The Frame Relay Switching Enhancements feature enables a router in a Frame Relay network to be used as a Frame Relay switch. This feature provides the following functionality:
Traffic Shaping on Switched PVCs
You can now configure Frame Relay traffic shaping on switched permanent virtual connections (PVCs). By applying traffic shaping to switched PVCs, you enable a router to be used as a Frame Relay port concentrator in front of a Frame Relay switch. The Frame Relay switch shapes the concentrated traffic before sending it into the network.
Frame Relay Switching over ISDN B-Channels
The Frame Relay Switching Enhancements feature enables you to transport Frame Relay data over ISDN so that small offices can be hubbed out of larger offices rather than connecting them directly to the core network. The hub router acts as a Frame Relay switch, switching between ISDN and serial interfaces.
The Frame Relay Switching Enhancements feature brings traffic policing functionality to user to network interface data communications equipment (UNI DCEs) in Frame Relay networks. When enabled on the interface, policing prevents traffic congestion by discarding or setting the discard eligible (DE) bit on packets that exceed specified traffic parameters.
Congestion Management on Switched PVCs
The Frame Relay Switching Enhancements feature enables a router in a Frame Relay network to manage outgoing traffic congestion on switched PVCs. When Frame Relay congestion management is enabled, the router manages congestion by setting BECN and FECN bits on packets, and by discarding packets that are marked with the DE bit and that exceed a specified level of congestion.
Platform: Cisco 7200 series routers
The Gatekeeper to Gatekeeper Redundancy and Load-Sharing feature expands the capability that is provided by the Redundant H.323 Zone Support feature. With the Redundant H.323 Zone Support feature, the location requests (LRQs) are sent simultaneously (in a "blast" fashion) to all of the gatekeepers in the list. The gateway registers with the gatekeeper that responds first. Then, if that gatekeeper becomes unavailable, the gateway registers with another gatekeeper from the list.
The Gatekeeper to Gatekeeper Redundancy and Load-Sharing Mechanism feature enhances this capability so that you can choose whether the LRQs are sent simultaneously or sequentially (one-at-a-time) to the remote gatekeepers in the list. If the LRQs are sent sequentially, a delay is inserted after the first LRQ and before the next LRQ is sent. This delay allows the first gatekeeper to respond before the LRQ is sent to the next gatekeeper. The order in which LRQs are sent to the gatekeepers is based on the order in which the gatekeepers are listed (using either the zone prefix command or the gw-type-prefix command).
Platforms: Cisco 7200 series routers
With the H.323 Support for Virtual Interfaces feature, you can configure the IP address of the gateway, so that the IP address included in the H.323 packet is deterministic and consistently indicates the same address for the source.
In previous releases of the Cisco IOS software, the source address included in the H.323 packet could vary depending on the protocol (RAS, H.225, H.245, or RTP). This makes it difficult to configure firewall applications to work with H.323 messages.
The H.323 Support for Virtual Interfaces feature addresses that difficulty providing the capability to explicitly configure an IP address to be used for all protocols.
Platform: Cisco 7200 series routers
Low Latency Queueing for Frame Relay is a feature that provides a strict priority queue (PQ) for voice traffic and weighted fair queues for other classes of traffic.
Using this feature you can configure classes of traffic according to protocol, interface, or access lists, and then define policy maps to establish how the classes are handled in the PQ and in weighted fair queues.
Queues are set up on a per-permanent virtual circuit (PVC) basis: each PVC has a PQ and an assigned number of fair queues. The fair queues are assigned weights proportional to the bandwidth requirements of each class; a class requiring twice the bandwidth of another will have half the weight.
The PQ is policed to ensure that the fair queues are not starved of bandwidth. When you configure the PQ, you specify in kbps the maximum amount of bandwidth available to that queue. Packets that exceed that maximum are dropped.
Platforms: Cisco 7200 series and Cisco 7500 series routers
With the Minimum Masking Ability for NetFlow Router-Based Aggregation Schemes feature you can set a minimum mask size. The IP address that is added to the aggregation cache is added to the maximum user-entered mask and the routing table mask.
To enable this feature on a Source Prefix or a Destination Prefix, or both, configure the desired Minimum Mask value using the NetFlow aggregation commands. The Minimum Mask value used by the router selects the granularity of the NetFlow data that will be collected.
The mask values range from 1 to 32. For coarse NetFlow collection granularity select a small Minimum Mask value. For fine NetFlow collection granularity select a large Minimum Mask value.

The explosive growth of the Internet has placed the focus on the scalability of Interior Gateway Protocols such as Open Shortest Path First (OSPF). The networks using OSPF are becoming larger every day and will continue to expand to accommodate the demand to connect to the Internet.
Internet service providers and customers with large networks have regularly complained that OSPF has a traffic overhead, even when the network topology is stable.
By design, OSPF requires link-state advertisements (LSAs) to be refreshed as they expire after 3600 seconds. Some implementations have tried to improve the flooding by reducing the frequency to refresh from 30 minutes to approximately 50 minutes. This solution reduces the amount of refresh traffic but requires at least one refresh before the LSA expires.
The OSPF Flooding Reduction feature works by reducing unnecessary refreshing and flooding of already known and unchanged information. To achieve this reduction, the LSAs are now flooded with the higher bit set, thus making them DoNotAge LSAs.

QSIG protocol support allows Cisco voice switching services to connect PBXs, key systems, and central office switches that communicate by using the QSIG protocol, which is becoming the standard for PBX interoperability in Europe and North America. QSIG is a variant of ISDN D-channel signaling. With QSIG, Cisco networks emulate the functionality of the public-switched telephone network (PSTN), and QSIG signaling messages allow the dynamic establishment of voice connections across a Cisco WAN to a peer router, which can then transport the signaling and voice packets to a second private integrated services network exchange (PINX). In addition, QSIG support can enable a toll-bypass application.

Using the Virtual Profile CEF Switched feature you can apply a per-user level configuration onto an Async and ISDN B-channel interface. VP CEF previously supported process switching and low-end system fast switching.
VP CEF switching provides improved performance by using Forwarding Information Base (FIB) to look up a route for a forwarding packet. FIB look-ups are superior to the cache tables used in fast switching because they are populated by routing topology rather than traffic and use the optimal switching decision.
VP CEF switching enables you to use VP in other new technologies that requires CEF switching, such as MPLS/BGP VPN, and dCEF with ISDN interfaces.

Voice over Frame Relay functionality has been updated in this release, so that configuration on all supported platforms is nearly identical. In Cisco IOS Release 12.0(4)T, when support for Voice over Frame Relay using FRF.11 and FRF.12 was introduced, configuration procedures were different depending on the router platform used.
Some commands introduced in earlier Cisco IOS releases have been removed or modified. Refer to the "Voice over Frame Relay Using FRF.11 and FRF.12 Configuration Updates" feature module for a description of the configuration procedures effective in this release.
This feature provides consistency for configuration requirements across the hardware models that support Voice over Frame Relay: the Cisco 2600 and 3600 series routers, the Cisco 7200 series routers, and the Cisco MC3810 multiservice access concentrator. In previous releases, configuration procedures on the Cisco MC3810 were different from those on other routers.

Cisco digital voice port adapters for the Cisco 7200 series routers provide large-scale voice and fax termination for PBXs, and the Public Switched Telephone Network (PSTN) using Voice over IP (VoIP) or Voice over Frame Relay (VoFR).
The digital voice port adapter is a highly integrated solution offering a leap forward in voice-channel density and application flexibility. This single-width port adapter incorporates two universal ports that can be configured for either T1 or E1 connections with high-performance digital signal processors that support up to 48 channels of compressed voice. Integrated channel service units/digital service units (CSU/DSU) echo cancellation, and digital signal level 0 (DS-0) drop and insert functionality eliminate the need for external line-termination devices and multiplexers, simplifying network design and management.

The AAA Broadcast Accounting feature allows accounting information to be sent to multiple authentication, authorization, and accounting (AAA) servers at the same time; that is, accounting information can be broadcast to one or more AAA servers simultaneously. This functionality allows service providers to send accounting information to their own private AAA servers and to the AAA servers of their end customers. It also provides redundant billing information for voice applications.
With the introduction of this feature, broadcasting is now allowed among groups of servers. The server groups can be either RADIUS or TACACS+. And each server group can define its backup servers for failover independently of other groups. (Failover is a process that may occur when more than one server has been defined within a server group. Failover refers to the following process: information is sent to the first server in a server group; if the first server is unavailable, the information is sent to the next server in the server group. This process continues until the information is successfully received by one of the servers within the server group or until the list of available servers within the server group is exhausted.
Thus, service providers and their end customers can use different protocols (RADIUS or TACACS+) for the accounting server. Service providers and their end customers can also specify their backup servers independently. As for voice applications, redundant accounting information can be managed independently through a separate group with its own failover sequence.

The Answer Supervision Report ing feature is an enhancement to the information request (IRR) Registration, Admission, and Status (RAS) protocol message that enables Gatekeepers to maintain call accounting information by reporting the call connection time of connected calls to the Gatekeeper.
In H.323 configurations, direct call-routed signaling is utilized by the endpoint (gateway). Gatekeepers do not have real-time knowledge or control over the state of a call and are dependent on the endpoints to provide them the necessary real-time information, such as the call connect time, call termination time, and call termination reason.
When a call ends, the gateway sends a Disengage Request (DRQ) message with the BillingInformationToken (which contains the duration of the call) to the Gatekeeper. However, if the Gatekeeper does not receive the DRQ message for some reason, the Gatekeeper does not receive the information about call start or duration, and the accounting information is no maintained accurately.
The Answer Supervision Reporting feature addresses the need to report the call connection time to the Gatekeeper upon call connection and at periodic intervals thereafter. The Answer Supervision Reporting feature adds a proprietary Cisco parameter, the call connection time parameter, to the perCallInfo parameter in the nonStandardData field, which is located in the IRR message. When a CONNECT message is received, the originating gateway sends the unsolicited IRR message to its Gatekeeper. On sending a CONNECT message, the terminating gateway sends the unsolicited IRR message to its Gatekeeper. If the admission confirmation message has a nonzero value for the IRRfrequency parameter, the gateway sends the unsolicited IRR message to its Gatekeeper at periodic intervals, which are determined by the value in the IRRfrequency parameter.
With the exception of containing the call connection time in the perCallInfo parameter, the IRR message and its functionality remains the same.

Common Open Policy Service (COPS) is a protocol for communicating network traffic policy information to network devices. Resource Reservation Protocol (RSVP) is a means for reserving network resources—primarily bandwidth—to guarantee that applications transmitting end-to-end across the Internet will perform at the desired speed and quality. Combined, COPS with RSVP gives network managers centralized monitoring and control of RSVP, including the ability to:

The Ecosystem Gatekeeper Interoperability Enhancements feature supplements the existing support for alternate gatekeepers and adds support for the alternate gatekeeper field (altGKInfo) to the gatekeeper rejection (GRJ) and registration rejection (RRJ) messages. This allows a gateway to move between gatekeepers during the gatekeeper request (GRQ) and registration request (RRQ) phases.
The altGKInfo consists of two subfields: the alternateGatekeeper and the altGKisPermanent flag. The alternateGatekeeper is the list of alternate gatekeepers. The altGKisPermanent flag indicates whether the gatekeepers in the associated alternateGatekeeper field are permanent or temporary.
If the current state of altGKisPermanent flag is true, then the new altGKInfo of any registration, admission, and status (RAS) messages received from one of the alternate gatekeepers is accepted, and the new list replaces the existing list.
If the current state of altGKisPermanent flag is false, then the altGKInfo of any RAS messages received from one of the alternate gatekeepers is ignored.
If the current permanent gatekeeper becomes nonresponsive and the altGKisPermanent flag is set to false, then the gateway sets the internal state of the altGKisPermanent flag to true. This setting enables the gateway to accept the alternate gatekeeper list from one of the gatekeepers in the existing alternate gatekeeper list.
The handling of the altGKInfo field varies depending on whether it is included in a GRJ or an RRJ message.

IKE Ex tended Authentication (XAUTH) is a draft RFC developed by the Internet Engineering TaskForce (IETF) based on the Internet Key Exchange (IKE) protocol. XAUTH allows all Cisco IOS authentication methods, including those based on RADIUS or TACACS+ servers, to perform both user and device authentication for remote users and clients.
The XAUTH feature is an extension to the IKE feature, and does not replace IKE authentication.

The Gateway-to-Gatekeeper Billing Redundancy feature enhances the accounting capabilities of the Cisco H.323 Gateway and provides support for Vocaltec Gatekeepers. The Gateway-to-Gatekeeper Billing Redundancy feature provides redundant billing information to an alternate gatekeeper if the primary gatekeeper to which a gateway is registered becomes unavailable.
During the process of establishing a call, the primary gatekeeper sends an admission confirmation (ACF) message to the registered gateway. The ACF message includes the user billing information and an access token. To provide the billing information to an alternate gatekeeper if the primary gatekeeper is unavailable when the call session ends, the access token information sent in the ACF message is now also included in the disengage request (DRQ) message that is sent to the alternate gatekeeper.
This features enables the alternate gatekeeper to obtain the billing information required to successfully complete the transaction.

The ISDN Network Side PRI feature enables Cisco IOS to replicate the public switched network interface to a PBX that is compatible with the ETSI Net5 switch type.
Routers and PBXs are both traditionally customer premises equipment (CPE) with respect to the public switched network interfaces. For Voice over IP (VoIP) applications, it is desirable to interface access servers to PBXs with the access server representing the public switched network.
Enterprise organizations use the current VoIP features with Cisco products as a method to reduce long distance costs for phone calls within and outside of their organizations. However, there are times that a call cannot go over VoIP and the call needs to be placed using the public switched telephone network (PSTN). The customer then must have two devices connected to a PBX so that some calls can be placed using VoIP and some calls can be placed over the PSTN. By contrast, with this feature, Cisco access servers can connect directly to user-side CPE devices such as PBXs. Voice calls and data calls can be placed without requiring two different devices to be connected to the PBXs.
With this feature, the access server can provide a standard ISDN PRI network-side interface to the PBXs and can mimic the behavior of legacy phone switches. To a PBX, the access server functions as a Net5 PRI switch. No change in PBX capability or behavior is required.

The Point-to-Point Protocol over Ethernet (PPPoE) on ATM feature provides the ability to connect a network of hosts over a simple bridging-access device to a remote access concentrator. With this model, each host utilizes its own PPPoE stack and the user is presented with a familiar user interface. Access control, billing and type of service can be handled on a per-user, rather than a per-site, basis. Before a point-to-point connection over Ethernet can be provided, each PPP session must learn the Ethernet address of the remote peer and establish a unique session identifier. A unique session identifier is provided by the PPPoE Discovery Stage Protocol.

Pragmatic General Multicast (PGM) is a reliable multicast transport protocol for multicast applications that require reliable, ordered, duplicate-free multicast data delivery from multiple sources to multiple receivers. PGM guarantees that a receiver in a multicast group either receives all data packets from transmissions and retransmissions, or detects unrecoverable data packet loss. PGM is offered as a solution for multicast applications with basic reliability requirements. PGM has two main parts: a host element (also referred to as the transport layer of the PGM protocol) and a network element (also referred to as the network layer of the PGM protocol).
The transport layer of the PGM protocol consists of two main parts: a source part and a receiver part. The transport layer defines how multicast applications send and receive reliable, ordered, duplicate-free multicast data from multiple sources to multiple receivers. The PGM Host feature is the Cisco implementation of the transport layer of the PGM protocol.
The network layer of the PGM protocol defines how intermediate network devices (such as routers and switches) handle PGM transport data as the data flows through a network. The PGM Router Assist feature is the Cisco implementation of the network layer of the PGM protocol. Refer to the "IP Multicast" section of the Cisco IOS IP and IP Routing Configuration Guide for information about the PGM Router Assist feature.

The Service Assurance (SA) Agent is both an enhancement to and a new name for the Response Time Reporter (RTR) feature that was introduced in Cisco IOS release 11.2. Using this feature you can monitor network performance between a Cisco router and a remote device (which can be another Cisco router, an IP host, or a mainframe host, by measuring key Service Level Agreement (SLA) metrics such as response time, network resources, availability, jitter, connect time, packet loss, and application performance.You can perform troubleshooting, problem analysis, and notification based on the statistics collected by the SA Agent.
The SA Agent Enhancement feature introduces new performance measurement operations and enhancements to assist in the measurement of SLAs. With Cisco IOS release 12.1(1)T, the SA Agent provides new capabilities so that you can:

Secure Shell (SSH) is a protocol that provides a secure, remote connection to a router. There are currently two versions of SSH available, SSH Version 1 and SSH Version 2. Only SSH Version 1 is implemented in Cisco IOS.
The SSH server feature enables an SSH client to make a secure, encrypted connection to a Cisco router. This connection provides functionality that is similar to an inbound Telnet connection. The SSH server in Cisco IOS works with publicly and commercially available SSH clients.

A wildcard pre-shared key allows a group of remote users with the same level of authentication to share an IKE pre-shared key. The remote peer pre-shared key must match the local peer pre-shared key for IKE authentication to occur. The term "wildcard" means that any remote peer with the pre-shared key can access the local peer, regardless of the remote peer IP address assignment. The term "pre-shared key" is a shared secret key exchanged during IKE negotiation.
A wildcard pre-shared key is usually distributed through a secure out-of-band channel. In a remote peer-to-local-peer scenario, any remote peer with the IKE pre-shared key configured can establish IKE security associations with the local peer.
The Wildcard Pre-shared Ke y feature is an enhancement to the crypto isakmp key global configuration command. With a wildcard IP address of 0.0.0.0 and pre-shared key authentication method configured on the local router, the local router can authenticate the IKE security associations with any remote peer that has a matching wildcard pre-shared key.
