Cross-Platform Release Notes for Cisco IOS Release 12.0S
OL-1617-14 Rev. Q0
Caveats
Resolved Caveats—Cisco IOS Release 12.0(32)S6
Workaround: Reload standby RP.
CSCsg66019
Symptoms: After an RPR+ switchover traffic ingress on a SIP-600 and egress on 4xGE ISE LC or
10xGE E4+ LC was being forwarded on the wrong VLAN.
Conditions: This symptom has been observed when an RPR+ switchover occurs.
Workaround: There is no workaround.
CSCsg71033
Symptoms: On a Cisco 12816 running Cisco IOS Release 12.0(32)S5, the E6 card continues to be
crashed to IPC timeout when deactivating the standby CSC and activating the CSC. The same
problem occurs when deactivating a SFC and activating the SFC.
E6 card continues to be crashed to IPC timeout which was caused by continuosly incremental CRC
errors in FIA from output of the show controller fia command until the whole Cisco 12816 chassis
is reload.
Workaround: Reload the Cisco 12816.
CSCsg75241
Symptoms: GSR Engine 2 -8xOC3 ATM LC ports stops traffic forwarding with %QM-4-STUCK
error.
Conditions: This symptom has been observed when there are bad packets hitting the GSR router,
especially those packets with sizes that GSR’s ATM SAR device can not handle. They include the
sizes 1 byte to 4 bytes small. Unexpected large packets also might cause similar issues. L2VPN
configuration exists on the Engine 2 ATM line-card and there are AAL0 VCs (encapsulation aal0).
Please note that these packets are errored or corrupted packets and are not intentionally generated
by regular traffic.
Workaround: Reload the Engine 2 ATM line-card.
CSCsg75269
Symptoms: QM-STUCK or QM-BUFFER-SANITY messages are logged continuously on Engine 2
ATM Line card of Cisco 12000 series router. The traffic in the egress direction of this line-card is
impacted and all packets are dropped on the Tx BMA.
It is very difficult to execute any command on the line card due to slow response and the above
continuous messages.
LC reset due to "RP unicast ping time-outs".
Conditions: This symptom has been observed when there are bad packets hitting the ATM SAR
device, especially those packets with sizes that ATM SAR device can not handle. They include the
sizes 1 byte to 4 bytes small. Unexpected large packets also might cause similar issues. L2VPN
configuration exists on the Engine 2 ATM line-card and there are AAL0 VCs (encapsulation aal0).
Please note that these packets are errored or corrupted packets and are not intentionally generated
by regular traffic.
Workaround: Reload the Engine 2 ATM line-card.
CSCsg76011
Symptoms: Certain packet corruption which changes bufhdr length to 0 can result in a line card
traffic disruption because of Alpha errors.
Conditions: This symptom has been observed with a Cisco 12000 router, Engine-3 line card, and
multicast traffic.
Workaround: There is no workaround.
