Cisco Cisco IOS Software Release 12.2(33)SRE

CSCui65914

Symptom: Minor or major temperature alarms are reported in the syslog along with the following 
DATACORRUPTION logs:

Aug 5 15:54:30.972 Buc: DATACORRUPTION-SP-1-DATAINCONSISTENCY copy error, -PC= 

0x414DEED4z -Traceback= 4027C4F4 419551C0 414DEED4 414E5BC4 414E0CA0 414E0F00 Aug 5 

15:54:30.972 Buc: C6KENV-SP-4-MINORTEMPALARM interface 10/0 outlet temperature crossed 

threshold #1(=60C). It has exceeded normal operating temperature range.

Conditions: The symptom is observed on ES+ series linecards of Cisco 7600 Series Routers.

Workaround: There is no workaround.

CSCuj30702

Symptom: This bug is specific to port channel sub interface configuration in ES+ card. This bug is 
not relevant to any other port channel configuration in ES+, that is, EVC/Bridge-Domain over PoCH 
sub-int etc, and other card types, such as ES20/ LAN cards are free from this bug. Any type of IP 
communication on port channel sub interfaces in ES+ cards fail. Such an issue is seen only with port 
channel sub interfaces on ES+ and not seen with port channel main interfaces.

Conditions: This symptom will only be seen with images where the fix of CSCuh40617 is integrated.

Workaround: The connections will work fine if it is moved to the main interface or by using EVC 
BD configurations.

CSCuj82897

Symptom: The “control-word” length is not set properly for small HDLC packets running over 
HDLC AToM VC with SIP-200. For example: SPA-8XCHT1/E1.

Conditions: This symptom occurs when HDLC AToM VC with SIP-200 is deployed, for example, 
SPA-8XCHT1/E1, will result in a packet length mismatch issue or dropping by the remote PE router 
when HDLCoverMPLS runs over the Ethernet link adding an additional padding which cannot be 
classified at all.

Workaround: Use SIP-400.

CSCul27327

Symptom: On the Cisco c7600 router, if PIM is configured on the port-channel and on the port 
members, any failure on one of the port members will disable the FE CAM.

Conditions: This symptom occurs when PIM is configured on the port members.

Workaround: Perform the following workaround:

Do not configure PIM sparse-mode on the port members even though the CLI is accepted.

In case the PIM sparse-mode is configured on the port members, remove it from the port 
members and the port-channel and then reapply the PIM configuration on the port-channel only.

Further Problem Description: A similar issue (CSCtf75608) is seen on the Cisco Catalyst 6500 
Series Switches, but the workaround is to configure PIM on the port-channel and the port members 
to avert the FE CAM to be disabled in the event of one of the port members failing. 

CSCul52239

Symptom: Multicast traffic might get affected after an interface delete and reconfiguration. This is 
more likely to happen in dot1q sub-interfaces in ES+ and specifically only if the delete and 
reconfiguration of the interface is done within 30 seconds.

Conditions: This symptom occurs in Cisco IOS Release 12.2SREx and Cisco IOS 15S based 
releases.

Workaround: Perform interface delete and reconfiguration with a time gap of one minute.
