Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
Conditions: Occurred during testing of an internal build of Cisco IOS Release 12.2SR. All of the
affected tunnels are configured with tunnel protection.
Workaround: Remove the configuration from all the tunnels where double configuration is seen in
the running configuration. Reapply the proper configuration and the router will start forwarding the
multicast traffic.
CSCsr57780
Symptoms: Drop rate and offer rate counters are incorrect with Distributed Link Fragmentation and
Interleaving over Frame Relay (dLFIoFR).
Conditions: Occurs when Cisco 7600 router is configured for shaping of frame-relay traffic.
Workaround: There is no workaround.
CSCsr86826
Symptoms: A standby SP may experience a memory leak in the mls-hal-agent process.
Conditions: This has been experienced on a Cisco 7600 router with dual SUP720s running either
Cisco IOS Release 12.2(33)SRC or Cisco IOS Release 12.2(33) SRC1. The router is configured for
multicast.
Workaround: There is no workaround.

table utilization is low.
Conditions: Occurs while flows are ingressing on ES20 module.
Workaround: There is no workaround.
Further Problem Description: The show mls netflow table-contention detail command will show
a heavy ICAM table utilization, while TCAM utilization is small.
Router#sh mls net table-contention det
Earl in Module 1
Detailed Netflow CAM (TCAM and ICAM) Utilization
================================================
TCAM Utilization : 0%
ICAM Utilization : 98%
Netflow TCAM count : 152
Netflow ICAM count : 126
