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.
SUMMARY STEPS
1. switch# configure terminal
2. switch(config)# errdisable detect cause {all | link-flap | loopback}
3. switch(config)# shutdown
4. switch(config)# no shutdown
5. switch(config)# show interface status err-disabled
6. (Optional) switch(config)# copy running-config startup-config
