Caveats

Resolved Caveats—Cisco IOS Release 12.0(31)S3

To bring up the member links after the symptom has occurred, enter the shutdown controller

configuration command followed by the no shutdown controller configuration command on the T3

controller of the SPA on which the multilink bundle is configured.

• CSCsa91478

Symptoms: A Cisco 12000 series that is configured for L2TPV3 may continuously log the following

CM_ERROR message, causing the syslog server to be flooded:

%SW_MGR-3-CM_ERROR: Connection Manager Error - unprovision segment failed

Conditions: This symptom is observed on a Cisco 12000 series that runs Cisco IOS

Release 12.0(30)S1 when a Multilink Frame Relay (MFR) interface is shut down in the

configuration of the connect command, causing proper provisioning to fail, unprovisioning to occur,

and the error message to be generated.

Possible Workaround: Enter the no shutdown interface configuration command on the MFR

interface.

• CSCsb00473

Symptoms: A channelized T3 to DS0 SPA hangs and remains unresponsive.

Conditions: This symptom is observed on a Cisco router when you configure a large number of

T1 links in SF framing mode simultaneously on channelized T3 to DS0 SPAs that are connected

back-to-back.

Workaround: Do not do configure a large number of T1 links in SF framing mode simultaneously

on channelized T3 to DS0 SPAs that are connected back-to-back. When the symptom has occurred,

you must reload the affected SPA.

• CSCsb11124

The Cisco IOS Stack Group Bidding Protocol (SGBP) feature in certain versions of Cisco IOS

software is vulnerable to a remotely-exploitable denial of service condition. Devices that do not

support or have not enabled the SGBP protocol are not affected by this vulnerability.

Cisco has made free software available to address this vulnerability for affected customers. There

are workarounds available to mitigate the effects of the vulnerability.

Cisco has published a Security Advisory on this issue; it is available at

http://www.cisco.com/warp/public/707/cisco-sa-20060118-sgbp.shtml.

• CSCsb12969

Symptoms: All VIPs or FlexWAN modules reload unexpectedly on a platform that is configured for

Modular QoS CLI (MQC).

Conditions: This symptom is observed on a Cisco 7500 series (with VIPs) and a Cisco 7600 series

and Cisco Catalyst 6500 series (both with FlexWANs) when the following steps occur while the

physical interface is in the UP state:

1. An input policy and output policy map are already attached to an ATM or Frame Relay PVC.

When you attach the same policy map to the main interface, an error message is generated and

the configuration is rejected.

2. You remove the policy map from the PVC and attach the same policy map to the main interface.

3. You remove the policy map from the main interface.

At this point, all VIPS or FlexWAN modules reload, even though no traffic is being processed during

the above-mentioned steps.

Workaround: There is no workaround.
