CSCsc34793 

RPM-XF: Cobalt ignored events 
lead to spurious increment of 
counters.

The following counter increments 
without bounds periodically in the 
show pxf dma counters:

PXF DMA FBB Line Card Error 

This happens when there is a 
Cobalt event that triggers the 
above error. There need not be 
further such Cobalt events; still 
the above counter increment.

None.

CSCse65135

CRC errors on Switch1 are not 
incremented due to invalid packet 
length.

Input errors on the Switch1 
interface of the RPM-XF or ATM 
VC may increment with no other 
reason counter incrementing to 
explain the cause. This is 
specifically due to input errors 
associated with lost or corrupt 
ATM cells. In the event the packet 
is discarded due to an invalid 
length, the VC and interface level 
CRC counters are not incremented.

Specific to the mxt4600 ATM 
hardware.

None.

CSCsi03950 

Malloc used during writing of PXF 
crash debug information.

Traceback while dumping cobalt 
packets in boot flash. 

Under rare conditions if there is 
pxf crash with a specific 
symptom, cobalt packets are 
dumped to boot flash and the 
problem happens while dumping 
the contents. 

None.

CSCsi92614

VSI process stack overflow causes 
card crash.

When connection goes into 
condition alarm state, and 
multicast is configured and it is 
oam managed. (oam-pvc manage 
0) 

None.
