Cisco Systems provides several software release "trains" based on a single version of Cisco IOS software. Maintenance releases of the Major train software (such as 11.3) deliver fixes to software defects only, thus providing the most stable software for your network, for the features you need. In addition to the Major train, there are Early Deployment (ED) trains. One ED train--Release 11.3 T--delivers both fixes to software defects and support for new Cisco platforms and new cross-platform features.

This release note discusses the following topics:

New Features in Release 11.3(1)T

The following new features are supported by the Cisco 7000 family of routers in Cisco IOS Release 11.3(1)T.

SNMP Manager--The SNMP Manager feature allows a router to serve as an SNMP manager. As an SNMP manager, the router can send SNMP requests to agents and receive SNMP responses and notifications from agents. When the SNMP manager process is enabled, the router can query other SNMP agents and process incoming SNMP traps.
SNMP Informs Requests--The SNMP Inform Requests feature allows routers to send inform requests to SNMP managers. Routers can send notifications to SNMP managers when particular events occur. For example, an agent router might send a message to a manager when the agent router experiences an error condition.

: SNMP notifications can be sent as traps or inform requests. Traps are unreliable because the receiver does not send any acknowledgment when it receives a trap. The sender cannot determine if the trap was received. However, an SNMP manager that receives an inform request acknowledges the message with an SNMP response PDU. If the manager does not receive an inform request, it does not send a response. If the sender never receives a response, the inform request can be sent again. Thus, informs are more likely to reach their intended destination.
: Because they are more reliable, informs consume more resources in the router and in the network. Unlike a trap, which is discarded as soon as it is sent, an inform request must be held in memory until a response is received or the request times out. Also, traps are sent only once, while an inform request may be retried several times. The retries increase traffic and contribute to a higher overhead on the network. Thus, traps and inform requests provide a trade-off between reliability and resources. If it is important that the SNMP manager receives every notification, use inform requests. On the other hand, if you are concerned about traffic on your network or memory in the router and you do not need to receive every notification, use traps.

x Digital Subscriber Line Bridge Support--The x digital subscriber line bridge support feature enables you to configure a router for intelligent bridge flooding for x digital subscriber line and other bridge applications.

Cisco IOS Feature Sets

This section lists Cisco IOS software feature sets available for the Cisco 7000 family of routers in Cisco IOS Release 11.3 T. Release 11.3 T supports the same feature sets as Release 11.3, but it might also have new features supported by the Cisco 7000 family of routers.

Feature Set Matrix

Table 3 provides a matrix of the new feature set organization and shows which feature sets are available on the Cisco 7000 family.

The tables use the following conventions to identify feature sets:

Yes: the feature set is offered for the platform
No: the feature set is not offered for the platform
Plus: a value-added option that contains a variable set of additional features depending on the hardware platform selected
Plus 40: a value-added option that contains a variable set of additional features depending on the hardware platform selected, including 40-bit data encryption
Plus 56: a value-added option that contains a variable set of additional features depending on the hardware platform selected, including 56-bit data encryption

Release 11.3 T Caveats

Refer to the Release Notes for Cisco IOS Release 11.3 publication for a list of the caveats that apply to Release 11.3. The caveats that apply to Cisco IOS Release 11.3 apply to Release 11.3 T.

The complete caveats against Release 11.3 are also available in the Cisco Documentation CD-ROM package. In the CD-ROM package, access the Cisco IOS 11.3 caveats in the Cisco IOS Release 11.3 database.

If you have an account on Cisco Connection Online (CCO), you can view additional caveats using the bug search tools in the Bug Toolkit, such as the Bug Navigator.

The following sections list caveats for Release 11.3 T that apply to the Cisco 7000 family of routers. For Release 11.3 T caveats for other Cisco products, refer to the specific product's release notes.

Release 11.3(1)T Caveats

This section describes possibly unexpected behavior by Release 11.3(1)T. Unless otherwise noted, these caveats apply to all 11.3 T releases up to and including 11.3(1)T.

Basic System Services

When frame relay traffic shaping is enabled on a serial interface, disabling and re-enabling weighted fair queuing will cause a system restart. [CSCdj58431]

Wide-Area Networking

The map-class commands frame-relay bc out and frame-relay be out are accepted by the enterprise image. These parameters are relevant for SVC setup. However, the traffic shaping code doesn't use them. As a result, the values appear to be unset. This behavior can be avoided by using the commands: frame-relay bc and frame-relay be. [CSCdj65624]

Cisco Connection Online

Cisco Connection Online (CCO) is Cisco Systems' primary, real-time support channel. Maintenance customers and partners can self-register on CCO to obtain additional information and services.
