Caveats
Resolved Caveats—Cisco IOS Release 12.0(32)S4
Conditions: This symptom is observed on a Cisco router when you attempt to remove a service
policy from a multilink interface.
Workaround: There is no workaround.
• CSCsc96270
Symptoms: Packets with a size greater then 604 bytes are not received from an ISE line card. This
situation is caused by the depletion of buffers, as indicated in the output of the show controller
tofab queue command.
Conditions: This symptom is observed rarely on a Cisco 12000 series and may be related to corrupt
or unidentified traffic.
Workaround: Reload the ISE line card.
• CSCsd12203
Symptoms: On a Cisco 7500 router, the standby may reload with CCB PLAYBACK errors when the
standby boots up.
Conditions: This symptom has been observed on a Cisco 7500 HA setup.
Workaround: There is no workaround.
Further Problem Description: There is no functional impact.
• CSCsd13490
Symptoms: An Engine 2 line card may crash when it receives multicast traffic that is not punted to
the CPU of the line card but switched by the PSA memory of the line card.
Conditions: This symptom is observed on a Cisco 12000 series that runs Cisco IOS
Release 12.0(27)S or a later release when the Engine 2 line card is configured with the wrong PSA
memory and when you enable multicast hardware acceleration by entering the hw-module slot
slot-number ip multicast hw-accelerate command.
Workaround: Disable multicast hardware acceleration on Engine 2 line card.
• CSCsd16581
Symptoms: An Engine 3 or Engine 5 line card may crash while processing packets for Output
Sampled NetFlow.
Conditions: This symptom is observed on Cisco 12000 series when Output Sampled NetFlow is
enabled on the Engine 3 or Engine 5 line card and when packets are sampled that are not aligned to
a 2-byte boundary.
Workaround: Disable Output Sampled NetFlow.
• CSCsd21134
Symptoms: A Cisco 12000 series line card may crash while processing packets that are not aligned
to a 4-byte boundary.
Conditions: This symptom is observed when the packet is processed in the CPU of the line card.
Workaround: There is no workaround.
• CSCsd45425
Symptoms: MLPPP interfaces may fail to ping the far end after initial configuration of the bundle.
Additionally, the IP address of the directly- attached MLPPP interface will not appear in the routing
table.
Conditions: This symptom has been observed with multilink PPP interface(s) configured on the
router.
