Enable Dot3 LLDP TLVs

About this task

Use this procedure to enable transmission of dot3 MAC/PHY configuration/status Link Layer Discovery Protocol (LLDP) TLV.

1. Enter GigabitEthernet Interface Configuration mode:

   enable

   configure terminal

   interface GigabitEthernet {slot/port[/sub-port][-slot/port[/sub-port]][,...]}

   

   Note

   If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.

2. Enable LLDP TLVs for transmission on a specific port:
   lldp tx-tlv dot3 {mac-phy-config-status}
3. Verify the configuration:
   show lldp tx-tlv dot 3

Example

Enable LLDP TLVs for transmission on a specific port:

Switch:1>enable
Switch:1#config
Configuring from terminal or network [terminal]? t
Enter configuration commands, one per line.  End with CNTL/Z.
Switch:1(config)#interface gigabitethernet 1/2
Switch:1(config-if)#lldp tx-tlv dot3 mac-phy-config-status

Switch:1(config-if)#show lldp tx-tlv dot3
