Hi, Thanks for the inputs.
I figured out that only one side had errdisable recovery for UDLD, and as the state machine (aggressive mode) didn't detected the neighbor after recovery, it wouldn't bring the interface down. The recommendation is not enable automatic recovery for UDLD, at all. Cheers. -----Mensagem original----- De: Antonio Soares [mailto:[email protected]] Enviada em: quinta-feira, 14 de julho de 2011 09:48 Para: Leonardo Gama Souza; 'Andrew Koch' Cc: [email protected] Assunto: RE: [c-nsp] UDLD misbehaviour Were you able to find if it was a permanent failure or intermittent failure ? If it was intermittent, you will have up and down interfaces with errdisable always trying to put the interface up and then udld putting it down again. For this reason, the automatic recovery should be disabled. And it seems in your case, you had it enabled with a 30 seconds timer, wasn't it ?
