[brocade ICX] how to look up the pvid of dual-mode ports
« on: May 15, 2015, 03:50:24 PM »
Hi,

I don't know how to look up the pvid of dual-mode ports. You know, there is a field called "pvid" in the output of "show interfaces brief". But in terms of a dual-mode port, it only shows the dual-mode VLAN ID number, which is not the pvid.

Anyone can help? Thanks

When you do the "show interface brief" it is showing you which VLAN is the PVID VLAN on those ports.  The PVID on a DualMode port must be the DualMode VLAN that is untagged.  Any other VLAN on the port has to be the secondary tagged VLAN.  I find the best way to see what VLAN's are on a port is "show vlan brief ethernet xx/xx/xx".  Since we know the PVID VLAN, any other VLAN has to be the tagged secondary VLAN.

Does that help?
