Caveats
Resolved Caveats—Cisco IOS Release 12.0(30)S
• CSCef64254
Symptoms: When there is a large MQC configuration, a Route Processor (RP) may crash because
of lack of memory.
Conditions: This symptom is observed on a Cisco 12000 series that is configured with ISE line cards
when you add a large number of classes to a policy map that is attached to a large number of
subinterfaces.
Workaround: There is no workaround.
• CSCef64744
Symptoms: On a 6-port channelized T3 line card that is enabled for QoS, a low latency queue (LLQ)
may not receive traffic that is mapped to the LLQ.
Conditions: This symptom is observed on a Cisco 12000 series that runs Cisco IOS
Release 12.0(28)S1.
Workaround: Reload the line card. If this is not an option, there is no workaround.
• CSCef66449
Symptoms: A PE router that functions in an EoMPLS environment may crash.
Conditions: This symptom is observed on a Cisco 10720 when 1200 circuits are configured in port
transparency mode.
Workaround: There is no workaround.
• CSCef66517
Symptoms: When you send larger than fragment-sized packets from an interface that has a traffic
shaping class configured, the packets get stuck when the queue size increases to the queue limit, and
subsequent traffic is tail-dropped.
Conditions: This symptom is observed when a policy is attached to a multilink interface that has a
traffic shaping class configured and when the interface is configured for fragmentation.
Workaround: There is no workaround.
• CSCef66562
Symptoms: The cbQosPolicyMapName object may stop functioning.
Conditions: This symptom is observed when an active view includes the ciscoPingMib.
Workaround: Either remove the cisciPingMib or include the lsystem keyword in the same view by
entering the snmp-server view PingMIB lsystem included command.
• CSCef67078
Symptoms: A PXF buffer leak occurs on an L2TPv3 decapsulation router, which van be observed in
the output of the show hardware pxf cpu buffer command:
router#show hardware pxf cpu buffer
FP buffers
pool size # buffer available allocate failures low buffer drops
