Related Commands
Use the show trunk command to display trunking information for the switch.
show trunk [mod_num[/port_num]] [detail]
Syntax Description
mod_num (Optional) Number of the module. /port_num (Optional) Number of the port. detail (Optional) Keyword to show detailed information about the specified trunk port.
Defaults
This command has no default setting.
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.
The Catalyst 2948G and 2980G switches are fixed configuration switches. Ports are located on module 2 for the 2948G and on modules 2 and 3 for the 2980G; for this reason, if you enter mod_num/port_num 1/N, an error message will be displayed.
