CatOS command for trunking

Answered Question
Jan 25th, 2008

What command is it to display what vlans are permitted over a trunk port, tagged, etc. And what command is it to set a vlan over a trunk port?

I can do this in IOS but need to know in CatOS.

I need to allow vlan 100,200 on this port.

Hi Sparky,

You can use command "show trunk" to get the status of all active trunking ports. To get the details of all allowed vlans on trunk port issue a command "sh trunk detail"

To add the vlans on existing trunk port use this command "set trunk
