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
PurposeCommand 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)#
