Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Resolved Caveats—Cisco IOS Release 12.0(29)S
Conditions: This symptom is observed on a Cisco router that runs Cisco IOS Release 12.0 S when
the interface has the rate-limit output command enabled.
Workaround: There is no workaround.
• CSCee06228
Symptoms: The SRP protocol on a Cisco uBR7246VXR may not fully initialize during the boot
sequence.
Conditions: This symptom is observed on a Cisco uBR7246VXR running Cisco IOS
Release 12.2(15)BC1b when one SRP side is wrapped. The symptom may also occur on a
Cisco 7200 series and is not release-specific.
Workaround: Force a wrap by entering the srp ips request forced-switch command and remove this
forced wrap. Note that you have to do this manually after a reload/reboot.
• CSCee06794
Symptoms: DTS may not work properly on dot1q Fast Ethernet subinterfaces. Traffic is not shaped
at the expected rate
Conditions: This problem is observed on a Cisco 7500 series that is configured as a PE router and
that runs Cisco IOS Release 12.2(12i). The symptom may also occur in other releases.
Workaround: If this is an option, use ISL subinterfaces.
• CSCee07351
Symptoms: LC-ATM-enabled subinterface on a PE router stays in “not ready” state when viewing
the LDP session to the LSC using the show mpls ldp discovery command. The shutdown interface
command followed by the no shutdown interface command will not clear the problem when
performed on either the LC-ATM subinterface on the PE or the Xtag interface on the connected LSC.
Conditions: The interface stays in “interface not LDP ready” state when there exists a stray LVC on
the switch interface. The PE reaches this state after multiple LDP flaps.
Workaround: The condition may be cleared by entering the clear ip route prefix command where
prefix is the local loopback address for the LC- ATM subinterface. This will cause all tailend LVCs
on all LC-ATM subinterfaces to be torn down and re-established, causing a brief customer outage.
This workaround should only be used if no alternate path exists for MPLS traffic towards this device
(i.e., a redundant LC-ATM subinterface). After using this workaround, user should confirm that the
expected number of LVCs has been re- established with the output of the show mpls atm summary
command. If bindings are not successfully re-established, repeat the clear ip route prefix command,
or reload the router.
Reload of the router will remove the stray LVC and bring the LDP session on the PE’s LC-ATM
subinterface back to normal state.
• CSCee09533
Symptoms: Flapping an interface may cause a router that is configured for L2TPv3 to crash.
Conditions: This symptom is observed on a Cisco router that has many L2TPv3 sessions and tunnels
configured. For example, the symptom occurs with 2000 sessions over 2000 tunnels but also with
4000 sessions over one tunnel.
Workaround: There is no workaround.
• CSCee12235
Symptoms: A Cisco platform reloads because of a watchdog timer expiration.
