error-disable on the switch port

[sam-lee]

Hi All,

Does anyone know what does this mean?

FastEthernet0/11 is down, line protocol is down (err-disabled)

[ovt]

The system has many reasons to errdisable a port ;) Read command ref. about "errdisable detect cause" command.

You can turn off error disable feature with command

You can also turn on error disable recovery with command

Hi,

This is a general error condition when a port has been disabled by the Catalyst Switch.

Maybe this is a STP or ARP Security issue.

You could use something like this to enable the reporting of more specific cause that disable the port

(config)#errdisable detect cause
