Enabling the Error-Disabled Detection

Command or Action
Step 4
switch(config-if)# no cdp enable
The following example shows how to enable CDP for an Ethernet port:
switch# configure terminal

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. config t
2. errdisable detect cause {all | link-flap | loopback}
3. shutdown
4. no shutdown
5. show interface status err-disabled
6. copy running-config startup-config
