An error is detected on a switch port and switch port put into err disable state. what is the steps you would take to recover port from this state?

there are two basic steps to recover switch port from this state. first before recovering the switch port try to find out what caused the switch port to be put in this state: issue the command

sw(config)err disable detesct cause{all/cause-name}

now; to recover port two methods

manually:switch port must be reenabled manually by issuing:

sw(config-if)#shutdown

sw(config-if)#no shutdown

sw(congfig-if)#exit

automatically:

sw(config)#err disable recovery cause{all/cause-name}

err disable port stays down for 300s. to change this

sw9config)#err disable recovery interval seconds

swconfig-if)#no shutdown

verification:

sw#sh int typr mod/no

sw#sh int status

check for:int type mod/no is up line protocol is up

to see all ports in in err disable state:

sw#sh int status err-disable
