Enabling the Error-Disabled Detection

You can enable error-disable (err-disabled) detection in an application. As a result, when a cause is detected
on an interface, the interface is placed in an err-disabled state, which is an operational state that is similar to
the link-down state.

Procedure

Purpose

Command or Action

Enters configuration mode.

config t

Example:

switch# config t
switch(config)#

Step 1

Specifies a condition under which to place the
interface in an err-disabled state. The default is
enabled.

errdisable detect cause {all | link-flap |
loopback}

Example:

switch(config)# errdisable detect cause

all

switch(config)#

Step 2

Brings the interface down administratively. To
manually recover the interface from the
err-disabled state, enter this command first.

shutdown

Example:

switch(config)# shutdown
switch(config)#

Step 3

Brings the interface up administratively and
enables the interface to recover manually from
the err-disabled state.

no shutdown

Example:

switch(config)# no shutdown
switch(config)#

Step 4

Displays information about err-disabled
interfaces.

show interface status err-disabled

Example:

switch(config)# show interface status
err-disabled

Step 5

(Optional) Copies the running configuration to
the startup configuration.

copy running-config startup-config

Example:

switch(config)# copy running-config
startup-config

Step 6

This example shows how to enable the err-disabled detection in all cases:

switch(config)#

errdisable detect cause all

switch(config)#
