Usage Guidelines

Enter no shutdown to enable the interface.

If you use in-band management only, you may choose to shut down the management interface (which is considered out of band). When the management interface is shut down, all services (such as ping, scp, telnet, ssh, snmp, firmwaredownload, and supportsave) through the management interface IP. Management interface shutdown is a persistent configuration, meaning that the interface remains down after a system reboot or failover.
