Caveats
Resolved Caveats—Cisco IOS Release 12.0(32)S12
Conditions: The conditions under which this symptom occurs are unknown.
Workaround: There is no workaround.
• CSCsq77980
Symptoms: When traffic is flowing over the default mdt and a remote PE’s edge facing slot is
reloaded, slot-mask may become zero on the UUT, which also has local switching.
Conditions: This defect is observed with Cisco IOS Release 12.0(32)S11.
Workaround: Enter the clear ip mds linecard command for the affected slot.
• CSCsq80773
Symptoms: Slow-path multicast fragmentation is not happening correctly. One of the output
interfaces is not receiving the packets in case of MVPN traffic.
Conditions: This symptom is observed with MVPN traffic with fragmentation on one of the
interfaces on E5.
Workaround: There is no workaround.
• CSCsq83540
Symptoms: A Cisco 12000 works as a PE, and an Eng5 SIP line card is used to face the CE. In the
VRF, the default route 0.0.0.0 is learned from the remote PE. When the problem occurs, all traffic
from the CE that is forwarded via the VRF default route is dropped.
Conditions: This symptom is observed on a Cisco 12000 Eng5 SIP line card that is running
Cisco IOS Release 12.0(32)SY04, 12.0(32)SY05, or 12.0(32)SY06. When VRFs are created and
deleted, new VRFs that are created will have a problem if they are allocated with a table ID allocated
for older deleted VRFs.
Workaround:
1. Reload the ingress Eng5 line card that is facing the CE.
or
2. If the customer does not want to reload the line card, a second workaround can be attempted, but
it is not a reliable workaround and may not always be successful. Create a new VRF without
removing any VRFs, which gets a new table ID, and apply the VRF configuration completely
wherever the old VRF configuration is applied.
Further Problem Description: This problem cannot be cleared by using the clear cef linecard x or
clear ip route vrf xxx 0.0.0.0 commands.
• CSCsq93004
Symptoms: Removal of a subinterface may cause memory corruption or a crash. The symptoms are
unpredictable.
Conditions: The symptoms are rare and will be observed only if a subinterface is configured for
mpls traffic-eng auto-tunnel primary use, and the subinterface is later removed from the
configuration.
Workaround: Do not remove subinterfaces.
• CSCsr11332
Symptoms: In rare situations, the show controller SONET port command might crash the RP.
