| | | | Bug Id: | CSCtz40435 | Title: | L4 Port-range ACL does not work on EVC on whales | |
Description: | Symptoms: The L4 port-range security ACL does not work on EVC.
Conditions: This symptom is seen when security ACL containing L4 port range
operation that is applied on EVC. The behavior is not as expected. The same
works on physical interface.
Workaround: Add support for L4 port range operation similar to the case of
applying it on physical interface.

| | | | Bug Id: | CSCug36858 | Title: | MET consumption increases continuously and is not freed up | |
Description: | Symptom:
Traffic through the 3600 causes MET consumption to increase continuously.
Conditions:
When traffic flows through an me3600, met consumption is increasing continuously. This eventually leads to met resources getting exhausted. The device could start throwing tracebacks and show unpredictable behavior. It could even eventually lead to crash of the box.
Workaround:
There are no known workarounds. Increasing the mac aging helps mitigate the issue. However, it doesn't fix it and will only delay the failure.
Further Problem Description:
met leak effecting multi cast functionality

| | | | Bug Id: | CSCto98272 | Title: | TCAM Array Parity errors found during POST | |
Description: | Symptoms: The following error is set on Power-On Self-Test (POST) for a few
ME3600 units:
POST: PortASIC CAM Subsystem Tests : Begin
TCAM APErr is set
POST: PortASIC CAM Subsystem Tests : End, Status Failed
Subsequent action is a crash, and the unit never boots up.
Another signature, is that the unit would go ahead and crashdump, in the IGMP subsystem init, at bootup. Watch out for this symptom, in case the boot up logs could not be captured.
Conditions: This symptom is observed on the default Cisco IOS load sequence,
when POST is enabled.
Workaround: This is not a hardware defect and does not need a unit RMA. It is a
software fault due to an erroneous initialization of the parity scan engine of
the TCAM. To prevent this error, use the boot-skip_post
command to load the IOS image. Otherwise, upgrade to an image which has the fix
for CSCtn38836 and CSCto98272.
