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.

New and Changed Information

The following is a list of the new hardware and software features supported by the Cisco 3600 series for Release 12.1(3a) T1. These features are broken down by feature in Tables 4,5,6 and 7.

New Hardware Features in Cisco IOS Release 12.1(3a) T1

There are no new hardware features supported in Cisco IOS Release 12.1(3a) T1.

New Hardware Features in Cisco IOS Release 12.1(2) T

The following new hardware features are supported by the Cisco 3600 series for Cisco IOS Release 12.1(2) T.

ATM OC-3 Network Modules with Circuit Emulation

Circuit emulation is a service based on ATM Forum standards that allows communications to occur between AAL1 CES and ATM UNI interfaces, that is, between non-ATM telephony devices (such as classic PBXs or TDMs) and ATM devices (such as Cisco 2600 and 3600 series routers). Thus, a Cisco 2600 or 3600 series router equipped with an ATM OC-3 network module with circuit emulation service offers a migration path from classic T1/E1 data communications services to emulated CES T1/E1 unstructured (clear channel) services or structured (N x 64) services in an ATM network.

The following network modules are available:

ATM T3 and E3 Network Modules (CSCdr03836)

Two new ATM network modules are supported on the Cisco 2600 Series and Cisco 3600 Series routers in this release. These network modules support ATM Adaptation Layer 5 (AAL5) and will provide North American 44.736 Mbps ATM T3 services, and European 34.368 Mbps E3 services.

These network modules provide DS3 and E3 ATM connectivity for the Cisco 2600 and 3600 Series routers. These network modules can be used to provide connectivity with campus networks and LAN switches, and long-haul WAN applications. These network modules include support for ATM LANE, RFC1577, RFC1483, TAG switching, and PPP over ATM with full support for both client and server functions. The modules support up to 1,024 simultaneous virtual circuits (VCs) and provide extensive traffic shaping and rate queuing capabilities on a per- VC basis. Use of these modules requires using one of the Cisco IOS Plus feature sets.

The following modules are available:

New Software Features in Cisco IOS Release 12.1(3a) T1

The following new software features are supported by the Cisco 3600 series for Cisco IOS Release 12.1(3a) T1.

CEF Support for IP Routing between IEEE 802.1Q vLANs

The CEF Support for IP Routing between IEEE 802.1Q vLANs feature provides the support needed for a CEF feature module.

Multicast Hoot and Holler Conferencing over IP

Cisco Hoot and Holler Conferencing over IP is powered using Cisco's VoIP technology, Cisco's IP multicast and Cisco's new DSP audio mixing. This solution provides the ability to transport Hoot and Holler traffic over Cisco equipment. Traditional Hoot and Holler networks are a point-to-multipoint voice applications and are commonly used by brokerage and trading firms to advise brokers and traders on market movements. Brokerage and trading firms can spend millions of dollars in monthly leased line charges to pay for dedicated circuit-switched leased Hoot and Holler long distance connections. The Cisco Hoot and Holler over IP solution enables customers to eliminate these expensive charges while protecting investments in existing Hoot and Holler equipment such as turrets, bridges and four wire phones. The Cisco Hoot and Holler over IP features are implemented with a Cisco IOS software upgrade and is supported over voice-enabled Cisco 2600 and 3600 modular multiservice platforms.

Source Specific Multicast (SSM)

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.

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 Cisco implementation of the IP Multicast lite suite of solutions targeted for audio and video broadcast application environments.

Trunk Conditioning for FRF.11 and Cisco Trunks

Trunk Conditioning for FRF.11 and Cisco Trunks is an enhancement that adds the following capabilities to the trunk conditioning feature on the Cisco 2600 and 3600 series routers and Cisco MC3810 series concentrators:

This feature applies to analog telephony connections and digital T1/E1 using CAS/robbed-bit "ABCD" signaling. It does not apply to digital T1/E1 connections using CCS type signaling.

PSTN Fallback

PSTN Fallback provides a mechanism to monitor congestion in the IP network and either redirect calls to the PSTN or reject calls based on the network congestion. PSTN Fallback does not provide assurances that a call that proceeds over the IP network is protected from the effects of congestion. This is the function of the other QoS mechanisms such as IP RTP Priority or low latency queueing (LLQ).

Caller ID

Caller ID (sometimes called CLID or ICLID for incoming call line identification) is an analog service offered by a Central Office (CO), which supplies calling party information to subscribers. Typically, the calling party number, and sometimes the name, appears on a station (also called extension) device such as a PC telephony software application screen or the display on a telephone. Type 1 Caller ID provides the calling party information while the call is ringing, and Type 2 Caller ID provides the additional convenience of calling number display while the recipient is on another call. In this release, Cisco provides only Type 1 Caller ID support.

RSVP Support for LLQ

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.

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.

Secure Shell Version 1 Integrated Client

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 software.

The Secure Shell Version 1 Integrated Client feature is an application running over TCP/IP to provide 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 that of an outbound Telnet connection except that the connection is encrypted. With authentication and encryption, the SSH client allows for a secure communication over an insecure network. The SSH client in Cisco IOS software works with publicly and commercially available SSH servers.

Event MIB

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 Management Information Base (MIB) objects on a local or remote system using SNMP and initiate simple actions whenever a trigger condition is met (for example, an SNMP trap can be generated when an object is modified). By allowing notifications based on events, the Network Management System (NMS) does not need to constantly poll managed devices to find out if something has changed. When combined with the Expression MIB support introduced in Cisco IOS Release 12.0(5)T, Event MIB support in Cisco IOS software provides a flexible and efficient way to monitor complex conditions on network devices.

T.38 Fax Relay for VoIP H.323

T.38 Fax Relay for VoIP H.323 provides standards-based fax relay protocol support for H.323 gateways and gatekeepers. T.38 is an ITU-T recommended standard for fax relay and has been implemented on Cisco 2600, Cisco 3640, and Cisco MC3810 multiservice gateways. Since T.38 is a standards-based implementation for fax relay, Cisco gateways and gatekeepers are able to interwork with third-party H.323 devices that support T.38 protocol.

Transparent Common Channel Signalling (T-CCS)

Transparent Common Channel Signalling (T-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.

T1/E1 Voice PRI Q.931, R2, T-CCS, WAN/Voice, E1 CAS and RAI

Frame Relay ELMI Address Registration (CSCdp36027)

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, NMS could detect only the topology of routers or the topology of switches. This new 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.

Bridging between IEEE 802.1Q vLANs

This feature supports integrated routing and bridging, transparent bridging, and PVST+ between vLANs (virtual LANs) with IEEE 802.1Q encapsulation features. It 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:

Enhancements to the Session Initiation Protocol for VoIP

Session Initiation Protocol enhancements include:

Feature Group D Support on Digital T1/E1 Packet Voice Trunk Network Modules

Adds Feature Group D Support on Digital T1/E1 Packet Voice Trunk Network Modules.

PPP Over ATM SVC

PPP over ATM SVC implements standards-based PPP over ATM AAL5.

Configuration through SNMP (CSCdj10821)

Configuration through SNMP creates messages that are printed to the console when configuration occurs using SNMP (for example, configuration done from a NMS). Previously notifications were only sent to the console when the configuration was changed from the IOS command-line interface.

Circuit Interface Identification MIB (CSCdp81924)

The Circuit Interface Identification MIB feature adds support for a new Cisco enterprise MIB, used for monitoring individual circuits using SNMP. The Circuit Interface Identification MIB (CISCO-CIRCUIT-INTERFACE-MIB) provides a MIB object that can be used to provide a description of individual circuit-based interfaces (for example, interfaces using ATM or Frame-Relay). This description will then be returned when linkup and linkdown SNMP traps are generated for the described interface.

Individual SNMP Trap Support (CSCdp97172)

The Individual SNMP Trap Support feature adds the ability to enable or disable SNMP system management notifications (traps) individually. SNMP traps that can be specified are "authentication", "linkup", "linkdown", and "coldstart". This feature expands the functionality of the snmp-server enable traps snmp command.

SNMP Support for IOS vLAN Subinterfaces (CSCdk25367)

This enhancement provides sparse table support for fastethernet subinterfaces similar to what is currently provided for frame-relay subinterfaces.

HSRP Support for ICMP Redirect Messages (CSCdp37610)

The HSRP (Hot Standby Router Protocol) Support for ICMP Redirect Messages feature enables ICMP redirects on interfaces configured with HSRP. This functionality works by filtering outgoing ICMP redirect messages through HSRP, where the next-hop IP address may be changed to an HSRP virtual IP address.

FXO Supervisory Disconnect Tone (CSCdr29301)

If the FXO Supervisory Disconnect Tone feature is configured and a detectable tone from the PSTN or PBX is detected by the digital signal processor (DSP), the analog FXO port goes on-hook. This feature prevents an analog FXO port from remaining in an off-hook state after an incoming call is ended. You can configure a voice port to detect either of the following tone types:

As part of the tone detection process by the DSP, a DSP event is reported to the host software.

Detection of any tone is effective only during call set-up (before a call is answered), and echo cancellation must be enabled to prevent disconnection due to detection of the router's own ringback tone.

WCCP Redirection on Inbound Interfaces (CSCdr39764)

The WCCP Redirection on Inbound Interfaces feature adds support to Cisco IOS software for the redirection of Web Cache Coordination Protocol (WCCP) traffic on inbound interfaces. Prior to this release, WCCP Version 2 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.

New Software Features in Cisco IOS Release 12.1(2) T

The following new software features are supported by the Cisco 3600 series for Cisco IOS Release 12.1(2) T.

Bidirectional PIM

Bidir-PIM is a variant of the Protocol Independent Multicast (PIM) suite of routing protocols for IP multicast. In PIM, packet traffic for a multicast group is routed according to the rules of the mode configured for that multicast group. The Cisco IOS implementation of PIM supports three modes for a multicast group:

A router can simultaneously support all three modes or any combination of them for different multicast groups. In bidirectional mode, traffic is only routed along a bidirectional shared tree that is rooted at the rendezvous point (RP) for the group. In bidir-PIM, the IP address of the RP acts as the key to having all routers establish a loop-free spanning tree topology rooted in that IP address. This IP address does not need to be a router, but can be an unassigned IP address on a network that is reachable throughout the PIM domain. Using this technique is actually the preferred configuration for establishing a redundant RP configuration for bidir-PIM.

QSIG Protocol Support

QSIG protocol support allows Cisco voice switching services to connect private branch exchanges (PBXs), key systems (KTs), and central office switches (COs) 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 wide-area network (WAN) to a peer router, which can then transport the signaling and voice packets to a second private integrated services network exchange (PINX).

QSIG support includes the following capabilities:

Frame Relay Switching Enhancements: Shaping and Policing

The Frame Relay Switching Enhancements: Shaping and Policing feature enables a router in a Frame Relay network to be used as a Frame Relay switch.

This feature includes the following Frame Relay switching enhancements:

Voice Busyout Enhancements

The local voice busyout feature provides a way to busy out a voice port if a monitored network interface changes state. When a monitored interface changes to a specified state—to out-of-service or in-service —the voice port presents a seized/busyout condition to the attached PBX or other customer premises equipment (CPE). The PBX or other CPE can then attempt to select an alternate route.

Local voice busyout is supported on analog and digital voice ports using channel associated signaling (CAS).

This feature allows you to perform the following tasks:


Note   This feature is different from busy-back, the signal sent from the network to the calling party to indicate a busy (or congested) state along the route.

Voice over Frame Relay Configuration Updates Using FRF.11 and FRF.12

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. This document describes the configuration procedures effective in this release.

In addition, this release provides support for digital voice calls for Voice over Frame Relay on the Cisco 2600 and 3600 series routers. In previous releases, the Cisco 2600 and 3600 series only supported analog voice calls for Voice over Frame Relay.

Airline Product Set Enhancements (CSCdp64339)

The ALPS Enhancements feature in Cisco IOS Release 12.1(2) T introduces additions to the ALPS service messages and extensions to the ALPS P1024B Airline Control (ALC) protocol support. This feature includes customized options to configure the format, address, and transmission of service messages. The ALPS ALC support is extended to be more scalable. This feature is an enhancement to the existing ALPS technology.


Note   Remote routers must have the Cirrus Logic CD2430 chipset on a synchronous serial interface module to connect to the ALC or UTS ASCUs.

Dial Peer Enhancements

The dial peer configuration enhancements were previously implemented in 12.1(1)T for Voice over IP on several platforms. In the 12.1(2) T release, these same enhancements are now supported on additional platforms for Voice over Frame Relay and Voice over ATM. In addition, these enhancements are now supported on the Cisco MC3810 for Voice over IP.

H.323 Support for Virtual Interfaces (CSCdp50546)

The H.323 Support for Virtual Interfaces feature allows users to configure the IP address of the gateway, so that the IP address include 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 by allowing the user to explicitly configure an IP address to be used for all protocols

OSPF Flooding Reduction (CSCdp80470)

The explosive growth of the Internet has placed the focus on the scalability of Interior Gateway Protocols such as 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 around 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 Do Not Age (DNA) LSAs.

AAA Server Group Deadtimer (CSCdp13160)

The AAA Server Group Deadtimer feature allows each authentication, authorization, and accounting (AAA) server to be fully configured in the server group. Thus, it allows you to 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 to be 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.


Note   The deadtime attribute is supported only for RADIUS hosts.

Configurable Timers in H.225 (CSCdp30190)

The Configurable Timers in H.225 feature allows users to 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 fail-over. In other cases, users might need a greater timeout value.

The Configurable Timers in H.225 feature addresses those needs by allowing the user to override the default of 15 seconds and configure the timeout value.

Frame Relay PVC Interface Priority Queuing (CSCdm71937)

The FR PIPQ feature provides an interface-level priority queueing scheme in which prioritization is based on destination PVC rather than packet contents. For example, FR PIPQ allows you to 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

Low Latency Queuing for Frame Relay (CSCdp27126)

Low Latency Queueing for Frame Relay is a new feature that provides a strict priority queue (PQ) for voice traffic and weighted fair queues for other classes of traffic. Before the release of this feature, low latency queueing was available at the interface and ATM virtual circuit (VC) levels. It is now available at the Frame Relay VC level when Frame Relay traffic shaping is configured.

Low Latency Queueing, also called priority queueing/class-based weighted fair queueing (PQ/CBWFQ), is a superset of and more flexible than previous Frame Relay Quality of Service offerings, in particular Real-Time Transport Protocol (RTP) prioritization and priority queueing/weighted fair queueing (PQ/WFQ).

Ecosystem Gatekeeper Interoperability Enhancements: Phase 2 (CSCdp70719)

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.

The Ecosystem Gatekeeper Interoperability Enhancements: Phase 2 allows gateways to move between gatekeepers without requiring a reconfiguration of the gateway or a gatekeeper failover in the gateway.

Gateways can be configured to switch from their primary gatekeeper to an alternate gatekeeper if a failure or outage occurs. If an outage occurs and gateways move from one gatekeeper to another, there may be an imbalance in the number of gateways registered to each gatekeeper. The Ecosystem Gatekeeper Interoperability Enhancements: Phase 2 helps to restore the balance (when the outage has been corrected) by allowing some of the gateways to be moved back to their proper gatekeepers.

Gatekeeper to Gatekeeper Redundancy and Load-sharing (CSCdp95233)

The Gatekeeper to Gatekeeper Redundancy and Load-Sharing Mechanism feature expands the capability that is provided by the Redundant H.323 Zone Support feature. The Redundant H.323 Zone Support feature, which was introduced in Cisco IOS Software release 12.1(1)T, allows users to configure multiple gatekeepers to service the same zone or technology prefix by sending location requests (LRQs) to two or more gatekeepers.

With the Redundant H.323 Zone Support feature, the 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 by allowing the user to 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 or the gw-type-prefix command).

Once the local gatekeeper has sent LRQs to all the remote gatekeepers in the list (either simultaneously or sequentially), if it has not yet received a location confirmation (LCFs) then it opens a "window". During this window, the local gatekeeper waits to see if a location confirmation (LCF) is subsequently received from any of the remote gatekeepers. If no LFC is received from any of the remote gatekeepers while the window is open, then the call is rejected.

COPS for RSVP

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 across the internet will perform at the desired speed and quality. COPS with RSVP gives network managers centralized monitoring and control of RSVP, including the ability to:

Voice Over ATM

Voice over ATM on Cisco 3600 series routers extends support for Voice over ATM, previously available only on the Cisco MC3810 to the Cisco 3600 series routers. Voice over ATM enables a Cisco 3600 series router to carry voice traffic (for example, telephone calls and faxes) over an ATM network.

Voice over ATM enables a Cisco 3600 to carry voice traffic, (for example, telephone calls and faxes) over an ATM network by using ATM encapsulation AAL5.

Restrictions:

Voice over ATM on the Cisco 3600 series requires that you install one of the following modules:

  The Multiport T1/E1 ATM network module with IMA supports up to 8 T1/E1 lines. For more information, see the Cisco IOS Release 12(05)T online document Configuring Multiport T1/E1 ATM Network Modules with Inverse Multiplexing over ATM on Cisco 2600 and 3600 Series Routers.
  The OC3 ATM Network Module supports one OC3 line. For more information about the Digital T1 packet voice trunk network modules, see the Cisco IOS Release 12.0(3)T online document ATM OC-3 Network Module for the Cisco 3600 Series Routers.

SGCP Call Control Protocol Support on the Cisco MC3810 and 3600 series routers

Simple Gateway Control Protocol (SGCP) enables intelligent external call agents to control gateways in Voice over IP (VoIP) environments. Gateways include trunking and residential gateways. Call agents include Telecordia SM 1.5 and third-party products. This release supports SGCP Version 1.1+.

SGCP is used in large IP networks typical of competitive local exchange carriers (CLECs) and Internet exchange carriers (IXCs).

New Software Features in Cisco IOS Release 12.1(1)T

The following new software features are supported by the Cisco 3600 series for Cisco IOS Release 12.1(1)T.

AAA Broadcast Accounting (CSCdk39995)

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 fail over independently of other groups. (Fail over is a process that may occur when more than one server has been defined within a server group. Fail over refers to the process by which 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 sent to one of the servers within the server group or until the list of available servers within the server group is exhausted.)

Answer Supervision Reporting (CSCdp21888)

The Answer Supervision Report feature is an enhancement to the information request (IRR) Registration, Admission, and Status protocol (RAS) 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 will not have the information about when the call started or the duration of the call, which is necessary to maintain accounting information.

The Answer Supervision Reporting feature addresses the need to report the call connection time to the Gatekeeper upon the connection of a call and at periodic intervals thereafter. The Answer Supervisor 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 (ACF) message has a nonzero value for the IRR frequency parameter, the Gateway sends the unsolicited IRR message to its Gatekeeper at periodic intervals, which are determined by the value in the IRRfrequency parameter.

Asynchronous Rotary Line Queuing

The Cisco IOS software Asynchronous Rotary Line Queuing feature allows Telnet connection requests to busy asynchronous rotary groups to be queued so that users automatically obtain the next available line, rather than needing to try repeatedly to open a Telnet connection. The Cisco IOS software sends a periodic message to the user to update progress in the connection queue.

Connections are authenticated using the method specified for the line configurations for the asynchronous rotary group. If a connection is queued, authentication is done prior to queuing and no authentication is done when the connection is later established.

H.323 Version 2, Phase 2

Cisco H.323 Version 2 Phase 2 adds the following benefits to Cisco H.323 Gatekeepers, gateways, and proxies:

Dial Peer Enhancements

The following enhancements to dial peer configuration lower complexity of dial planning and reduces the amount of effort in creating dial peer entries:

Ecosystem Gatekeeper Interoperability Enhancements (CSCdp48320)

The Ecosystem Gatekeeper Interoperability Enhancements feature allows gateways to move between gatekeepers without requiring a reconfiguration of the gateway or a gatekeeper failover in the gateway.

Gateways can be configured to switch from their primary gatekeeper to an alternate gatekeeper if a failure or outage occurs. If an outage occurs and gateways move from one gatekeeper to another, there may be an imbalance in the number of gateways registered to each gatekeeper. The Ecosystem Gatekeeper Interoperability Enhancements helps to restore the balance (when the outage has been corrected) by allowing some of the gateways to be moved back to their proper gatekeepers.

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.

Gateway-to-Gatekeeper Billing Redundancy (CSCdp20240)

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's 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 in 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.

IKE Extended Authentication (CSCdm71322)

IKE Extended Authentication (Xauth) is a draft RFC developed by the Internet Engineering Task Force (IETF) based on the Internet Key Exchange (IKE) protocol. The Xauth feature is an enhancement to the existing Internet Key Exchange (IKE) Protocol feature. Xauth allows all Cisco IOS software AAA authentication methods to perform user authentication in a separate phase after the IKE authentication phase 1 exchange. The AAA configuration list-name must match the Xauth configuration list-name for user authentication to occur.

The Xauth feature is an extension to the IKE feature, and does not replace IKE authentication.

IKE Shared Secret Using AAA Server (CSCdp05026)

The IKE Shared Secret Using AAA Server feature enables key lookup from a AAA server. Pre-shared keys do not scale well when trying to deploy a large scale Virtual Private Network (VPN) without using a certification authority (CA). When using dynamic IP addressing such as DHCP or PPP dialups, the changing IP address can make key lookup difficult or impossible unless wildcard pre-shared key is used.

In the IKE Shared Secret Using AAA Server feature, the shared secret is accessed during the aggressive mode of IKE negotiation through the AAA server. The ID of the exchange is used as the username to query AAA if no local key can be found on the Cisco IOS router to which the user is trying to connect.

ISDN Network Side for ETSI Net5 PRI (CSCdm34916)

The ISDN Network Side for ETSI Net5 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 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 PSTN. The customer then must have two devices connected to a PBX to allow some calls to be placed using VoIP and some calls to be placed over the Public Switched Telephone Network (PSTN). In contrast, this feature allows Cisco access servers to connect directly to user-side CPE devices such as PBXs and allows voice calls and data calls to be placed without requiring two different devices to be connected to the PBXs.

This feature enables the access server to provide a standard ISDN PRI network side interface to the PBXs and to 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.

PPP over Ethernet on ATM

The PPP 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 done 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.

The PPPoE on ATM feature provides service-provider digital subscriber line (DSL) support. As service providers begin DSL deployments, two of their most significant goals are to ease and facilitate consumer end adoption and to preserve as much of the dialup model as possible. PPPoE serves to advance both of these goals by leveraging ethernet scale curves and embedded base (such as ATM NICs) and by preserving the point-to-point session used by internet service providers (ISPs) in today's dialup model.

Pragmatic General Multicast Host

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 can detect unrecoverable data packet loss. PGM is intended as a solution for multicast applications with basic reliability requirements.

Service Assurance Agent Enhancements

The SA Agent Enhancements feature enhances the management and measurement of enterprise and service provider networks. Service Level Agreements (SLA) are useful for managed network services such as managed WAN access and managed virtual private network (VPN) services. The SA Agent Enhancement feature provides tools for measuring network performance using FTP, which is one of the most popular traffic types in Internet service provider (ISP) networks, and jitter (one-way delay), which is important for applications such as Voice over IP (VoIP).

Session Initiation Protocol (SIP)

Voice over Internet Protocol (VoIP) currently implements ITU's H.323 specification within Internet Telephony Gateways (ITGs) to signal voice call setup. Session Initiation Protocol (SIP) is a new protocol developed by the Internet Engineering Task Force (IETF) Multiparty Multimedia Session Control (MMUSIC) Working Group as an alternative to H.323. SIP features are compliant with IETF RFC 2543, published in March 1999.

The Cisco SIP functionality equips the Cisco AS5300 access server, and the Cisco 2600 and Cisco 3600 series routers to signal the setup of voice and multimedia calls over IP networks; therefore, the SIP feature, introduced in Cisco IOS Release 12.1(1)T, provides an alternative to H.323 within the VoIP internetworking software.

Settlement for Packet Telephony with Roaming and Multiple Roots

This is the second release of Cisco's Open Settlement Protocol (OSP) features. Some settlement vendors have required roaming users to be authenticated and accounted for by the settlement clearinghouse. Therefore, this IOS Release 12.1(1)T introduces two new features, roaming and multiple roots.

  The roaming feature is configured by:
  The multiple roots feature allows a settlement server to use one certificate for a Secure Socket Layer (SSL) handshake and a different certificate for token signing.

Wildcard Pre-Shared Key Enhancement (CSCdm599913)

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's pre-shared key must match the local peer's 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's 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 (SAs) with the local peer.

The wildcard pre-shared key 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 SA with any remote peer that has a matching wildcard pre-shared key.

Important Notes

This section contains important information about use of your Cisco IOS Release 12.1(3a) T1 software.

The last maintenance release of the Cisco IOS Release 12.0T release train is 12.0(7)T. The migration path for customers needing bug fixes for Cisco IOS Release 12.0 T features is 12.1 Mainline. Cisco IOS Release 12.1 Mainline has the complete feature content of 12.0T and this release will eventually reach General Deployment (GD).

Cisco IOS Release 12.1 T begins with the same set of features as the Cisco IOS Release 12.1 mainline but will continue to add features.

Cisco IOS Release 12.1(3) T and 12.1(3a) T1 Voice Issues

Because of a number of issues with H.323 and SIP voice support on the Cisco AS5300, Cisco AS5800, Cisco 2600 series, Cisco 3600 series, and Cisco MC3810 which arose in Cisco IOS Release 12.1T, use of 12.1(3) T and 12.1(3a) T1 is strongly discouraged.

Cisco IOS Release 12.1(3) T and 12.1(3a) T1 is being made available for dial applications only. The problems with voice in this release are being tracked in the following DDTS reports:

Caveats

Caveats describe unexpected behavior or defects in Cisco IOS software releases. Severity 1 caveats are the most serious caveats; severity 2 caveats are less serious.

For information on caveats in Cisco IOS Release 12.1(3a) T1, see Caveats for Cisco IOS Release  , which lists severity 1 and 2 caveats, and is located on CCO and the Documentation CD-ROM.


Note   If you have an account with CCO, you can use Bug Navigator II to find caveats of any severity for any release. Click on this path: Software Center: Cisco IOS Software: Cisco IOS Bug Toolkit: Cisco Bug Navigator II. You can also find Bug Navigator II at
http://www.cisco.com/support/bugtools

The caveats listed in this section are open in Release 12.1(3a) T1.

  When initializing a Cisco router, the PRI receives the following message:
   Channel State (0=Idle 1=Propose 2=Busy 3=Reserved 4=Restart 5=Maint_Pend)
   0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 3 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
   Service State (0=Inservice 1=Maint 2=Outofservice)
   2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2
   E1 and primary-net5 will not work.
   Workaround: Enter the <CmdBold>isdn service dsl<CmdArg>0<noCmdArg> b_channel <CmdArg>0<noCmdArg> state <CmdArg>0<noCmdArg><noCmdBold> interface configuration command. Though doing so clears the problem, the initial situation recurs after reloading. E1 is not accessible unless you perform this workaround or the alternative workaround (below). If you reload the router, E1 will be inaccessible again.
   Alternative workaround: Perform a shut/no shut sequence of the controller. Though doing so clears the problem, the initial situation recurs after reloading.
  When voice and data are both running in Frame Relay Low Latency Queuing (FR LLQ) configuration, some of the data packets are being classified as voice. This will result in police and consequent drops for the packets in the priority queue and hence cause bad voice quality. The workaround is to turn on process-switching on the incoming interfaces for voice and data.

Open Caveats—Cisco IOS Release 12.1(2) T

The following caveats are specific to the Cisco 3600 Series platform:

CES Traffic

  Because of a known issue with the CES hardware, a structured T1 CES connection might not maintain synchronization across multiple timeslots for a T1 connection. Applications that require synchronous multiple timeslots (video, data) could be affected. This issue does not affect structured or unstructured E1 CES or unstructured T1 CES.
  For a workaround perform the following steps:
  1) remove the connect statement
  2) remove the tdm-group
  3) reconfigure the tdm-group
  4) reconfigure the connect statement
  This sequence may need to be repeated.

ATM Forum 3.1 Support

  The ATM OC-3 Network Module and OC-3/STM-1 ATM Circuit Emulation Service Network Module do not comply with ATM Forum specification 3.1. There is no workaround.

Obtaining Documentation

World Wide Web

You can access the most current Cisco documentation on the World Wide Web at http://www.cisco.com, http://www-china.cisco.com, or http://www-europe.cisco.com.

Documentation CD-ROM

Cisco documentation and additional literature are available in a CD-ROM package, which ships with your product. The Documentation CD-ROM is updated monthly. Therefore, it is probably more current than printed documentation. The CD-ROM package is available as a single unit or as an annual subscription.

Ordering Documentation

Registered CCO users can order the Documentation CD-ROM and other Cisco Product documentation through our online Subscription Services at http://www.cisco.com/cgi-bin/subcat/kaojump.cgi.

Nonregistered CCO users can order documentation through a local account representative by calling Cisco's corporate headquarters (California, USA) at 408 526-4000 or, in North America, call 800 553-NETS (6387).

Obtaining Technical Assistance

Cisco provides Cisco Connection Online (CCO) as a starting point for all technical assistance. Warranty or maintenance contract customers can use the Technical Assistance Center. All customers can submit technical feedback on Cisco documentation using the web, e-mail, a self-addressed stamped response card included in many printed docs, or by sending mail to Cisco.

Cisco Connection Online

Cisco Connection Online is the foundation of a suite of interactive, networked services that provides immediate, open access to Cisco information and resources at anytime, from anywhere in the world.
