CAT9200 stacked cisco cat9k error encountered in fed fwd asic register cmd invalid argument

[most_ahdy]

I have two Cat 9200-48p stacked switches with firmware version 16.12.4 CAT9K_LITE_IOSXE in INSTALL mode , at which i always receive the below console logs:

------------------ show platform hardware fed switch 2 fwd-asic register read register-name SifRacInvalidRingWordCnt-0 asic 1 core 0 ------------------

% Error: Error encountered in fed fwd asic register cmd Invalid argument

------------------ show platform hardware fed switch 2 fwd-asic register read register-name SifRacInvalidRingWordCnt-1 asic 1 core 0 ------------------

% Error: Error encountered in fed fwd asic register cmd Invalid argument,

The second member of the stack hang up many times, is this issue a firmware issue or hardware issue.

I wonder if someone faced this issue before

Thanks

Please perform a COLD REBOOT (pull the power cables) of the entire stack and see if this fixes things.

NOTE:  No, I am not joking about the COLD REBOOT.

Thanks Leo, I already did a cold reboot three times before and the issue always persist, do you think its a firmware issue or hardware issue.

Thanks

This looks like a firmware bug.  

You may need to raise a TAC Case and get them to look at it.
