err-disabled interface

[gaoyang]

On 3550, an interface is err-disabled, and must use shutdown/no shutdown command to reenable the interface, is there any method to let the switch reenable interfaces in err-disable state automatically

hi,

Yes , you need to apply following commands on switch :

switch(config)#errdisable recovery cause all

switch(config)#errdisable recovery interval 30

any event on switch which makes port to go in errdiable mode will recover itself within 30 sec. you cant set value less than 30 sec.

you can also define specific conditions other than "all" like loopback, udld, linkflap etc...

Thanks
