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

Syntax

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

no inter-switch-link

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.

NOTE:

This inter-switch-link {<PORT-NUM> | lag <LAG-ID>} command replaces the mclag inter-switch-link {<PORT-NUM> | lag <LAG-ID>} command that is supported only in 10.00 releases.

Command context

config-vsx

Parameters

<PORT-NUM>: Specifies a physical port on the switch. Some switches (such as the Aruba 8400 Switch Series), use the format member/slot/port (for example, 1/1/1). Other switches use slot/port (for example, 1/1). Sets the port to act as ISL

<LAG-ID>: Specifies the LAG ID. Run the show capacities command for the maximum number of VSX LAGs supported for your particular type of switch.
