show trunk

Use the show trunk command to display trunking information for the switch.

show trunk [mod[/port]] [detail]

Syntax Description

mod	(Optional) Number of the module.
/port	(Optional) Number of the port.
detail	(Optional) Keyword to show detailed information about the specified trunk port.

Defaults

This command has no default settings.

Command Types

Switch command.

Command Modes

Normal.

Usage Guidelines

Entering the show trunk command without specifying a module or port number displays the actively trunking ports.

To display the trunking configuration for a port that is not actively trunking, specify the module and port number of the port you want to display.

The RSM port displays as a port that is always trunking, with allowed and active VLANs for each VLAN configured on the RSM.
