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.
• CSCsu27304
Symptoms: IP Control Protocol (IPCP) goes down during initial negotiation, then gets re-negotiated.
Conditions: Occurred while bringing up the PPPoEoE session. Occurred on a Cisco 7600 router.
Workaround: There is no workaround.
• CSCsu35597
Symptoms: Renaming a directory gives error message.
Conditions: This happens on a Cisco router running Cisco IOS Release 12.4(20)T1.fc2 image
Workaround: There is no workaround.
• CSCsu38597
Symptoms: VPN routing/forwarding (VRF) ping from PE to locally attached CE fails.
Conditions: Problem is seen with WAN interfaces.
Workaround: Reconfigure the controller.
• CSCsu40667
Symptoms: A Cisco 7600 series router may fail to install some NetFlow entries even if NetFlow
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
