Configure LLDP DCBX TLVs

You can enable or disable the transmission of DCBX TLV types on a port. This example uses port 0/2.

1. Enable DCBX TLVs for PG, PFC, and the application.

   SEFOS# configure terminal
   SEFOS(config)# interface extreme-ethernet 0/2
   SEFOS(config-if)# lldp tlv-select dcb1tlv priority-group priority-flow-control application-etype-fcoe
   SEFOS(config)# end

2. View the TLV settings.

   SEFOS# show interfaces extreme-ethernet 0/2 dcb priority-group
    
   Port             :      Ex0/2
   Show Type        :      Admin Config
   Feature          :      Priority Group
