inter-switch-link {<PORT-NUM> | lag <LAG-ID>}

Description

Configures a physical port or a LAG as an interswitch link port. Only one port or LAG can be configured to act as an ISL. Once a port is configured as an ISL, it becomes a part of all VLANs in a system.

The no form of this command clears the configuration of the interswitch link port from a physical port or a LAG.
