err-disable state

[N. Deepak]

there is any reasons for switch port sfp module going to err-disable state

[John Blakley]

Can you post "show errdisable cause"?

HTH,

hope you can help me 

facing the same issue in Cisco WS-C3560-48TS-S

[swebhard]

could you paste the logs ? , sh log

the reason must be there itself

for example:

%PM-SP-4-ERR_DISABLE: udld error detected on Gix/y, putting Gi x/y in err-disable state

, so here the reason would be udld .

[devils_advocate · Accepted solution]

Which is the model number of the SFP you are using?

The following error suggests the switch does not support that module, is it a 3rd party one?

%PM-4-ERR_DISABLE: gbic-invalid error detected on Gi0/1, putting Gi0/1 in err-disable state

I 'think' Catalyst switches can have problems with third party SFP's so it may be worth doing the following to make the SFP work:

no errdisable detect cause gbic-invalid

service unsupported-transceiver

[N. Deepak]

Hi devils,

yes  your right,

im using non cisco tx:1310nm rx:1550nm module.

i changed the gig port in other side switch(Gi3 to Gi4), now its working..

and i used that

no errdisable detect cause gbic-invalid

command..

Thank you

[Raul Ricano]

Thanks for the command post.  This resolve the issue I was having also until we can get a new SFP put in.

[Luis Yepes]

I had the same problem, i changed the SFP and that resolved the problem.

[Amit_Poonia]

This worked for me.

If multiple interfaces are in this state then we have to use this command once on one of the interfaces and simply reset the other interfaces.
