## Determine Whether LLDP is Running and Recognizing Peers

In a correct DCB configuration, LLDP must be running and recognizing peers. If LLDP does not show the neighbors for port 2 and port 18, perform the following steps to determine whether the peers are configured correctly and both links are up.

1. Display the DCB administrative, operational, and peer configurations.

       SEFOS# show interfaces extreme-ethernet 0/2 dcb priority-group detail
       SEFOS# show interfaces extreme-ethernet 0/2 dcb priority-flow-control detail
       SEFOS# show interfaces extreme-ethernet 0/2 dcb application-etype-fcoe detail
       SEFOS# show interfaces extreme-ethernet 0/18 dcb priority-group detail
       SEFOS# show interfaces extreme-ethernet 0/18 dcb priority-flow-control detail
       SEFOS# show interfaces extreme-ethernet 0/18 dcb application-etype-fcoe detailshow
       SEFOS# show interfaces extreme-ethernet 0/2 dcb counters
       SEFOS# show interfaces extreme-ethernet 0/18 dcb counters

2. Display the VLAN information for the database.

       SEFOS# show vlan 201

       Vlan database
       -------------
       Vlan ID             : 201
       Member Ports        : Ex0/2, Ex0/18
       Untagged Ports      : None
       Forbidden Ports     : None
       Name                :
       Status              : Permanent

   In the following steps, DCB features are exchanged, and DCB is in operating mode with its peer.

3. Ensure that the interface is up on a specified port (port 0/2, in this example).

       SEFOS# show interfaces extreme-ethernet 0/2 description

       Interface    Status   Protocol
       ---------    ------   --------
       Ex0/2        up       up

4. Ensure that the interface is up on a specified port (port 0/18, in this example).

       SEFOS# show interfaces extreme-ethernet 0/18 description

       Interface    Status   Protocol
       ---------    ------   --------
       Ex0/18        up       up

5. Display the LLDP global configuration details.

       SEFOS# show lldp

       Chassis Id               : 00:14:4f:6c:5e:cf

6. Display information about the neighbors learned on the interfaces.
