Hi.

Please do a soft reset of the modulke which is showing this error.
'hw-module slot 4 reset' 

Kindly post the IOS version which you are running. There are many known bugs for these
error messages. I can look for it if anything matches with you issue.

Cheers

Hi,

you should do hw-module reset, the sup was not able to communicate with the line card 4 for some reasons. Though i guess the show module should have been showed the module 4 as unknown, but in this case it has not listed it.

Did the switch reset/reboot by itself when this happened?

Are there any crash logs ?

There is no risk reseting a module, except downtime of 5-10mins for the reset i believe.

I am not sure when the messages started as I just took this over. But the switch has been up for 29 weeks. I will reset the module this evening (i.e EST time).

I also just found out that the switch doesn't have anything in slot 4. Slot 4 and 6 are empty.

Run this command exactly matching the case...  

show platform chassis | inc pimPhyport

This will show this......

pimPhyport Gi3/17(64)

find the port that has (183) and you will find the port you are looking for.

I am sorry but the correct answer is from Mike. I made a mistake by clicking on Manju. Thanks all for your help. I very much appreciated it.

[manju.cisco]

LOL, my bad for assuming you had put line card on slot 4......hehe

Do you see any port in disabled/blocked status Tshi M?

especially the port which Mike helped to identify.

[Tshi M]

No worries Manju...I am working remotely so I don't have a visual of the device. In any case, Mike command helped me track down the port (see below).

pimPhyport Gi5/40(183)

I checked the port and it has a lot of output drops. The switchport is reporting at 1000/full. So, I will ask the user to move to another port and see if this still happening.

Total output drops: 576726

Thanks Mike, I will keep you posted.

[burleyman]

Glad I could help. I would also clear the counters to see if they increment.

When I had this happen it actually turned out to be a bad module. If you move them to the same module and you still have the same issue, try another module.
