Caveats
Resolved Caveats—Cisco IOS Release 12.0(30)S
• CSCef68547
Symptoms: FR links on 6-port channelized T3 and 2-port OC-3-channelized-to-DS1/E1 line cards
may not recover when all of the links are removed and reconfigured for an MFR bundle. The same
symptom may occur on serial interfaces.
Conditions: This symptom is observed when all links are removed from and re-added to the bundle
while the bundle is briefly in a shut down state.
Workaround: To re-establish the bundles, enter the hw-module slot shelf-id/slot-number reload
command. You can also delete and reconfigure the MFR interface or the serial interfaces. To prevent
the symptom from occurring, wait a couple of seconds between entering the shutdown command
and the no shutdown command when you remove and reconfigure the MFR bundle or serial
interfaces.
• CSCef77523
Symptoms: The protocol may go down on random Multilink Frame Relay (MFR) link bundles.
Conditions: This symptom is observed on a Cisco 12000 series that runs Cisco IOS
Release 12.0(28)S and that is configured with a 1-port channelized OC-12/STM-4 (DS1/E1) ISE
line card after you have reloaded the router.
Workaround: Enter the shutdown interface configuration command followed by the no shutdown
interface configuration command on the affected interface.
• CSCef82683
Symptoms: An MFR bundle may stay in the down state after redistributing bundle links. The output
of the show frame-relay multilink command displays as cause code “inconsistent bundle.”
Conditions: This symptom is observed when a Remove-Link message is lost.
Workaround: Enter the shutdown command followed by the no shutdown command on the affected
bundle.
• CSCin05330
Symptoms: When a multilink bundle interface is created by entering the interface multilink
group-name global configuration command, the Cisco Discovery Protocol (CDP) becomes
incorrectly disabled. If the cdp enable interface configuration command is used to enable CDP on
the multilink bundle interface, the command is not saved in the startup configuration and CDP
remains disabled after the router is reloaded.
Conditions: This symptom is observed on a Cisco platform that is configured with a multilink bundle
interface.
Workaround: There is no workaround.
• CSCin79140
Symptoms: A router crashes when you apply a map-class configuration to a subinterface that has
been unconfigured and reconfigured.
Conditions: This symptom is observed when the following sequence of events occurs:
1. Configure a Frame Relay subinterface.
2. Unconfigure the Frame Relay subinterface.
3. Reconfigure the Frame Relay subinterface.
4. Configure a map class on the subinterface.
Workaround: There is no workaround.
