## 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
       Enable           :      true
       Advertise        :      true
       Willing          :      false
       Group Bandwidth  :      40%     20%     40%     0%      0%      0%      0%      0%
       Priority Group ID:      0       0       0       1       2       2       2       2
       Max Traffic Class:      8

3. View the PFC settings.

       SEFOS# show interfaces extreme-ethernet 0/2 dcb priority-flow-control

       Port             :      Ex0/2
       Show Type        :      Admin Config
       Feature          :      Priority Flow Control
       Enable           :      true
       Advertise        :      true
       Willing          :      false
       Priority Mask    :      0       0       0       1       0       0       0       0
       Max Traffic Class:      8

4. View the application settings.

       SEFOS# show interfaces extreme-ethernet 0/2 dcb application-etype-fcoe

       Port             :      Ex0/2
       Show Type        :      Admin Config
       Feature          :      Application FcoE
       Enable           :      false
       Advertise        :      true

5. Disable DCBX TLVs for PG, PFC, and the application.

       SEFOS# configure terminal
       SEFOS(config-if)# no lldp tlv-select dcb1tlv priority-group priority-flow-control application-etype-fcoe
       SEFOS(config-if)# end

6. View the TLV settings after disabling them for the PG.
