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, the purchaser or user must obtain local import and use authorizations for all encryption strengths. Contact your sales representative or distributor for more information, or send an e-mail to export@cisco.com.

New and Changed Information

The following sections list the new features supported by the Cisco 2600 series for Cisco IOS Release 12.0(7)XK1.

New Hardware Features in Release 12.0(7)XK

High-Density Voice Network Module

Cisco 2600 and 3600 Series 10/100 Ethernet/Token Ring Mixed Media Network Modules

New Software Features in Release 12.0(7)XK

The following software features are available for the Cisco 2600 series in Cisco IOS Release 12.0(7)XK.

Voice over Frame Relay 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 differed depending on the router platform used.

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.

Note In Cisco IOS releases prior to Release 12.0(5)XE, the Cisco 7200 series could only act as a tandem router in Voice over Frame Relay topologies, and could not terminate VoFR calls. Beginning in Cisco IOS Release 12.0(5)XE and 12.1(1)T, the Cisco 7200 series can terminate VoFR calls.

Voice-Port Testing Enhancements

New voice-port testing commands force voice ports into specific states for testing:

Voice-Port Enhancements

The Cisco 2600, 3600, and MC3810 series routers and concentrators all support data, voice, and video transport to varying degrees. Numerous voice-port commands and features that were previously limited to one or two of these platforms have been extended to additional platforms, and differences in configuration commands have been reduced or eliminated.

These are new features on the Cisco 2600 and 3600 platforms in Cisco IOS Release 12.0(7)XK.

QSIG Protocol Support on Cisco MC3810, 7200, 2600, and 3600 Series Routers

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).

The Cisco voice packet network appears to the traditional QSIG PBXs as a distributed transit PBX that can establish calls to any PBX, non-QSIG PBX, or other telephony endpoint served by a Cisco gateway, including non-QSIG endpoints. When originating and terminating on QSIG endpoints, the QSIG messages are passed transparently across the network; the PBXs are responsible for processing and provisioning the supplementary services. When linking QSIG and non-QSIG endpoints served by a Cisco packet voice gateway, only basic calls are supported. In addition, all switched voice connections must be established and torn down in response to QSIG control messages.

QSIG support includes the following capabilities:

Limitations and Restrictions

Cisco IOS Release 12.0(7)XK1 contains the following limitations and restrictions. Unless otherwise indicated, these limitations and restrictions apply to all previous software releases as well.

Voice over Frame Relay

Caution Voice over ATM SVCs were first supported on the Cisco MC3810 in Cisco IOS Release 12.0(5)XK and 12.0(7)T. If upgrading a Cisco MC3810 from Release 12.0(5)XK or 12.(7)T to this release to obtain Voice over Frame Relay improvements, you will lose support for your Voice over ATM SVCs.

Important Notes

Beginning with Cisco IOS Release 12.0(7)XK, Cisco is changing the product numbers you use to order a specific Cisco IOS software image. In short, Cisco will remove the periods separating the release train, maitenance release, and build number. The following table provides some examples.

Old Product Number New Product Number Release Image Description

S364AR1K2-12.0.7XK=

S364AR1K2-12007XK=

S26CP-12.0.7XK=

S26CP-12007XK=

Cisco IOS Release 12.0(7)XK

Deprecated MIBs

Older Cisco Management Information Bases (MIBs) will be replaced in a future release. OLD-CISCO-* MIBS are currently migrated into more scalable MIBs, without affecting existing Cisco IOS products or NMS applications. Application developers should update from deprecated MIBs to the replacement MIBs as shown in the following table.

Caveats

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

This section only contains open and resolved caveats for the current Cisco IOS maintenance release.

All caveats in Release 12.0 and Release 12.0 T are also in Release 12.0(7)XK1.

For information on caveats in Cisco IOS Release 12.0, see Caveats for Cisco IOS Release 12.0  that describes caveats affecting all maintenance releases.

For information on other caveats that also apply to this release, see Caveats for Cisco IOS Release 12.0 T  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. You can reach Bug Navigator II on CCO at Software Center: Cisco IOS Software: Cisco Bug Toolkit: Cisco Bug Navigator II or at http://www.cisco.com/support/bugtools.

Open caveats for Release 12.0(7)XK1

This section describes possibly unexpected behavior by Release 12.0(7)XK1. Unless otherwise noted, these caveats apply to all 12.0 releases up to and including 12.0(7)XK1.

A Cisco router that is running Cisco IOS Release 12.0(04a) might receive the following alignment error messages on dot1q over Internetwork Packet Exchange service access point (IPX SAP):
%ALIGN-3-CORRECT: Alignment correction made at 0x605B8E70 reading 0x63E5A6F1 %ALIGN-3-TRACE: -Traceback= 605B8E70 60095714 60095700 00000000 00000000 00000000 00000000 00000000
IPX SAP is affected only when dot1q encapsulation is involved (such as when IPX SAP is configured on a dot1q interface).
These alignment error messages do not affect connectivity or cause packet loss. There is no workaround.
A Cisco router that has tag switching enabled and is running Cisco IOS Release 12.0(5)T might reload if a tag advertisement appears in a certain time window when a related routing update takes place. An ATM interface transition might cause this condition. There is no workaround.
A router may crash after entering the clear ip bgp * command on a peer PE router when running 12.0(5)T onwards, 12.1 and 12.0ST. The crash occurs with the following stack trace:
bgp_fwdentry_info bgp_v4class_update_fwdtable_walker rn_walktree_version bgp_update_fwdtable bgp_router
The crash occurs on the local PE when a PE iBGP session is cleared on the remote box.

Resolved caveats for Release 12.0(7)XK1

This section describes behavior that is now corrected in Cisco IOS Release 12.0(7)XK1.

Voice call attempted to some voice ports fail due to DSP channel nailup problem. This problem is related to incomplete cleanup at the end of voice call. So the next call to the same port fails due to a hanging call.
Busyout monitor may remain configured on a voice port after being de-configured through the CLI.
During boot, when bulk voice calls are attempted some voice ports get stuck in S_WAIT_HOST_DISC state. Before a setup request is sent to session app, if a disconnect is requested, the voice port gets locked in this state.
The router reports "VOICE ERROR 0x3A" when placing a outbound ISDN call. Incoming calls from the same router work fine.
Outgoing BRI data calls fail because they are incorrectly tagged as voice calls.
VOIP performance is seriously affected after changing codec complexity from high to medium unless the router is powered off and on.
Not able to configure G.729 codec from voice class codec, causing the call connection to fail.
