Caveats
Resolved Caveats—Cisco IOS Release 12.0(32)S10
Workaround: There is no workaround.
• CSCsl67815
Symptoms: When core-facing line card reloads or has link flap, the edge-facing E5 for mVPN may
not forward mVPN traffic.
Conditions: This defect is observed with an internal version off Cisco IOS Release 12.0(33)S.
Workaround: Enter the clear ip mds line <edge facing E5 lc slot> command.
• CSCsl81258
Symptoms: On a Cisco 12000 router running Cisco IOS Release 12.0(32)SY4, the SNMP ifIndex is
missing for subinterfaces of the first SPA of a Engine 5 SIP-600 Line Card, as follows:
router#sh snmp mib ifmib ifindex GigabitEthernet15/0/3.951 Invalid ifIndex for
GigabitEthernet15/0/3.951
This issue affects accounting and billing.
Conditions: Occurred after router was upgraded from Cisco IOS Release 12.0.(31)s6 to Cisco IOS
Release 12.0.(32)SY4.
Workaround: There is no workaround.
• CSCsl92482
Symptoms: Fragmentation is handled incorrectly on GSR E5 line card. We can send up to around
2Gbps of fragmented traffic without performance impact. When the egress line card CPU reaches
100%, the rate of the fragmented traffic drops down to 50Mbps.
Conditions: Occurs when all CPU resources of the egress LC are consumed.
Workaround: There is no workaround.
• CSCsl93926
Symptoms: E5 line card configured for CFI and BFI may crash when passing mVPN traffic.
Conditions: This is observed with Cisco IOS Release 12.0(32)SY5.
Workaround: There is no workaround.
• CSCsl98882
Symptoms: Traffic stops forwarding after the deletion of a security output ACL which is shared with
the other port on a two-port OC-192, with the port carrying the traffic having a feature-output ACL.
Conditions: Occurs on a two-port OC-192 E6 card. Both the ports should be configured with output
or input security ACLs, and one port which is carrying the traffic should have output or input ACL.
For this issue to happen, all the ACLs need to be either output or input type simultaneously.
Workaround: Configure a new ACL with a different name from the original ACL, then remove it.
The traffic can then be forwarded again.
Further Problem Description: This issue is specific to E6 alone and will not happen on E4.
• CSCsm02749
Symptoms: When multicast VPN routing/forwarding instance (mVRF) is un-configured, memory
leak may occur in line cards.
Conditions: This symptom is observed in Cisco 12000 Series Routers and Cisco 7500 Series Routers
when multicast distributed routing is enabled on VPN routing/forwarding instance.
Workaround: There is no workaround.
