The following sections list the new hardware and software features supported by the Cisco 1700 series routers for Release 12.1 T.
The following new software features are supported by the Cisco 1700 series routers for Release 12.1(3)T:
For the Cisco 1750 router, these enhancements provide compliance with all mandatory elements of H.323 Version 2 for the Cisco IOS based Gateway, Gatekeeper, and Proxy products. Along with other selected features, they provide critical new functionality needed for interoperablilty and network deployment. New features include:
Cisco IOS Release 12.1(3)T supports the following features:
To configure these features on Cisco 1700 series routers, see the online document Quality of Service Solutions Configuration Guide. From CCO, click on the path (under the heading Service & Support):

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. The SSH client supports the ciphers of Data Encryption Standard (DES), Triple DES (3DES), and password authentication.
The SSH client functionality is available only when the SSH server is enabled.
The following new software features are supported by the Cisco 1700 series routers for Release 12.1(2)T:
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 any unassigned IP address on a network that is reachable throughout the PIM domain. Using this technique is the preferred configuration for establishing a redundant RP configuration for bidir-PIM.
Membership to a bidirectional group is signalled via explicit Join messages. Traffic from sources is unconditionally sent up the shared tree toward the RP and passed down the tree toward the receivers on each branch of the tree.
Bidir-PIM is designed to be used for many-to-many applications within individual PIM domains. Multicast groups in bidirectional mode can scale to an arbitrary number of sources without incurring overhead due to the number of sources.
Bidir-PIM is derived from the mechanisms of PIM sparse mode (PIM SM) and shares many SPT operations. Bidir-PIM also has unconditional forwarding of source traffic toward the 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.
The Frame Relay Switching Enhancements 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:
Before the Frame Relay Switching Enhancements feature was introduced, routers had limited Frame Relay switching functionality. With this feature, a router acting as a virtual Frame Relay switch can be configured to do the following:
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 min to around 50 min or so.
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 (DNA) LSAs.
The Cisco 1700 series routers, which includes the Cisco 1720 and 1750 models, are modular access routers for small and medium businesses and small branch offices. Cisco 1700 routers deliver routing, firewall, and VPN functions for Internet data and voice applications.
The VPN module, which fits into a slot inside the Cisco 1720 or 1750 chassis, assists the host processor by accelerating layer 3 IP Security (IPSec) data and voice encryption and decryption. The VPN module supports DES and 3DES encryption algorithms, MD5 and SHA-1 hashing, and Diffie-Hellman key generation.
The VPN module encrypts data using DES and 3DES algorithms at speeds suitable for full duplex T1/E1 serial connections (4 megabits per second for 1518-byte packets). Equipped with a VPN module, a Cisco 1700 router supports up to 100 encrypted tunnels for concurrent sessions with mobile users or other sites.
Voice over Frame Relay (VoFR) enables a router to carry voice traffic (for example, telephone calls and faxes) over a Frame Relay network. Configuration information is available in the "Cisco IOS Multiservice Applications Configuration Guide" and "Cisco IOS Multiservice Applications Command Reference" publications.
Before configuring VoFR on a router, you must configure your Frame Relay backbone network. As part of your Frame Relay configuration, you need to configure the map class, and the Local Management Interface (LMI) among other Frame Relay functionality. For more information about Frame Relay configuration, refer to the ''Cisco IOS Wide-Area Networking Configuration Guide.''
The Cisco VoFR implementation allows the following types of VoFR calls:
The following new software features are supported by the Cisco 1700 series routers for Release 12.1(1)T:
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 software.
The SSH server feature enables a 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 software will work with publicly and commercially available SSH clients.
Cisco H.323 Version 2 Phase 2 enhancements upgrade several optional features of the H.323 Version 2 specification, and facilitate customized extensions to the Cisco Gatekeeper.

Note Certain devices are limited in their support of H.450. The Cisco 1700 and ubr820 platforms do not support Interactive Voice Response (IVR). Therefore, these platforms are not able to act as H.450 Transferring endpoints. |
Old Cisco Management Information Bases (MIBs) will be replaced in a future release. Currently, OLD-CISCO-* MIBs are being converted into more scalable MIBswithout affecting existing Cisco IOS products or NMS applications. You can update from deprecated MIBs to the replacement MIBs as shown in Table 5.

The following sections contain important notes about Cisco IOS Release 12.1 T that can apply to the Cisco 1700 series routers.
The Australian variant of the two-port Foreign Exchange Office (FXO) voice/fax interface card for the voice/fax network module (VIC-2FXO-M3) is not supported by the Cisco 1750 at this time.
Booting a Cisco 1700 series router with the commands boot flash or boot system flash results in unpredictable behavior. To work around this problem, be sure to enter a colon (:) following both commands (for example, boot flash: or boot system flash:).
Be advised that the fans in the Cisco 1700 series routers stay off untilthermally activated (45°C/115°F).
When using a multipartition flash card, the various flash partitions are referred to as "flash:1:", "flash:2:", etc. If you specify only "flash" in a multipartition flash, the parser assumes "flash:1:." For example, if you enter show flash all the parser defaults to "show flash:1: all" and only the flash information for the first partition displays. To see information for all flash partitions, enter show flash ?. This will list all of the valid partitions. Then enter show flash:xx: all on each valid partition.
On the ATM25 interface of the C1400 there are two types of traffic shaping: hardware-based and software-based. Hardware-based traffic shaping is provided by the ATM SAR chip and is enabled on a per-pvc basis by one of the following IOS PVC configuration commands:
ubr <peak-cell-rate>
ubr+ <peak-cell-rate> <minimum-guaranteed-cell-rate>
vbr-nrt <peak-cell-rate> <sustainable-cell-rate> <maximum-burst-size>
The SAR chip has "rate counters" that control the rate at which the current buffer up for segmentation is going to be transmitted. Ideally, the SAR chip could be programmed with values for all of the above command parameters. Unfortunately, it only has the rate counters, which specify a divisor of the basic line rate of 25 Mbps and which really sets the maximum transmission rate (peak-cell-rate) for the channel. Note that with the "ubr" and "ubr+" commands, the rate counter for the PVC is obtained from the <peak-cell-rate> parameter. With the "vbr-nrt" command, the rate counter is obtained from the <sustainable-cell-rate> parameter. While the <minimum-guaranteed-cell-rate> parameter in the "ubr+" command and the <peak-cell-rate> parameter in the "vbr-nrt" command can be specified by the user, they are ignored by the ATM25 driver.
Software-based traffic shaping is enabled on a per-interface basis via the "traffic-shape" interface configuration command. For performance reasons, and since for ATM interfaces you most likely want to do shaping on a per-pvc basis, the ATM driver does not support software-based traffic shaping while fastswitching. However, if fast-switching is disabled and the "traffic-shape" interface configuration command is enabled, then software traffic shaping will occur. (See CSCdk28377 for more information).
Caveats describe unexpected behavior in Cisco IOS software releases. Severity 1 caveats are the most serious caveats; severity 2 caveats are less serious, and so forth.
For information on caveats in Cisco IOS Release 12.1 T, see Caveats for Cisco IOS Release 12.1 T.
All caveats in Cisco IOS Release 12.1 are also in Cisco IOS Release 12.1 T.
For information on caveats in Cisco IOS Release 12.0, see Caveats for Cisco IOS Release 12.1, which lists severity 1 and 2 caveats and is located on CCO and the Documentation CD-ROM.

This section describes possibly unexpected behavior by Release12.1(3)T, specific to the Cisco 1750 router only. The following caveats are severity 3.
The Cisco 1750 router is a Residential Gateway (RGW) and supports MGCP on FXS ports only, therefore, do not configure MGCP on FXO or E&M ports.
From the perspective of the Cisco 1750 router command line interface (CLI), the format used to describe the slot and port is <slot>/<port>. However, after executing the command show mgcp endpoint, the Cisco 1750 router might display the output in the format <slot>/<subinterface>/<port>, such as 0/0/1 for port 0/1. The 0 digit for the <slot> does not represent hardware; it is a phantom number added by Cisco 1750 internal code because there is no concept of a subinterface for Cisco 1750 routers. This syntax structure matches that of some other networking equipment requiring unique specifications for all three hardware aspects:the slot number, the sub-unit number, and the port number. On the Cisco 1750 router, the <subinterface> is actually the slot number. The output format of the command show mgcp endpoint thus provides information about how to configure the command call agent.
This section describes possibly unexpected behavior by Release12.1(1)T, specific to the Cisco 1700 series routers. Only severity 1 and 2 caveats are included.
The Australian variant of the two-port Foreign Exchange Office (FXO) voice/fax interface card for the voice/fax network module (VIC-2FXO-M3) is not supported by the Cisco 1750 at this time.
