Viewing active vlans on a port-channel?

  • 1.  Viewing active vlans on a port-channel?

    Posted Feb 13, 2016 01:46 AM

    With my gigabit interfaces configured as trunks, I can see active vlans with "show interface gigabit xxx switchport".  However, the "switchport" option is not available for LACP configured port-channels with "show interface port-channel xxx".  What is available to quickly check what vlans are active on the port-channel?

    # show trunk

    Thanks,

    Thanks Raj, I guest that works. But not quite the same as looking at the list with the interface command, especially when you have 50+ vlans.  Just baffles me why it's the only command modifier not included.

    dwright,

     

    It is probably not used that often.  If you feel strongly about it, please request that feature at the ideas portal here:  https://arubanetworkskb.secure.force.com/cp/ideas/ideaList.apexp

    If the number of entries on your output is your concern, try running Raj's commands with an include statement:

     

    show vlan | include <PortChannelID>

    show trunk | include <PortChannelID>
