6500 EOBC channel is jammed

Answered Question

We've seen this error a few times now on a 6500, SUP1A with different FastEthernet and GigE cards, and have replaced 3 different cards, in 3 different slots.

(As per the online documentation).

At this point we don't think the issue is card related (contrary to the documentation).

As of now we have switched to the standby sup module.

Any suggestions are appreciated

If the issue is not happening with the standby sup, then have you tried replacing the sup1a?


Have you tried the cards that failed in other working slots?

Error Message    EOBC-2-EOBC_JAM: EOBC channel is jammed.  Attempting 
to diagnose the source of the problem and recover if possible. 

Explanation   This message indicates that the SP is unable to communicate with other processors in the system because of a problem with the EOBC channel. The problem could be due to faulty EOBC hardware on the supervisor engine or due to a module with a faulty connector to the EOBC channel. The SP will attempt to recover automatically. The success of this automatic recovery will be communicated through more messages.

Recommended Action   No action is required.


Error Message    EOBC-2-EOBC_JAM_RECOVERED: [chars] in slot [dec] is

Explanation   This message indicates that the specified module has faulty hardware and is adversely affecting the operation of the switch. The remaining modules will be power cycled and brought online.

I had the same message and replaced the module in the reported slot and the problem was fixed.


Good luck
