Temporarily disabling a port

To temporarily disable a port without changing its stored configuration attributes, enter the following command at any prompt:

Main# /oper/port <port number>/dis

Because this configuration sets a temporary state for the port, you do not need to use apply or save. The port state will revert to its original configuration when the switch is reset. See the “Menu information” section in the “Operations Menu” chapter for other operations-level commands.
