Configure LLDP Tx-TLVs

About this task

Use this procedure to configure optional management Link Layer Discovery Protocol (LLDP) TLVs for transmission.

LLDP TLVs for transmission are enabled by default.

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. To disable LLDP TLVs for transmission, enter:
   no lldp tx-tlv {local-mgmt-addr | port-desc | sys-cap | sys-desc |sys-name}
3. To restore LLDP TLVs to their default value, enter:
   default lldp tx-tlv {local-mgmt-addr | port-desc | sys-cap | sys-desc |sys-name}
4. Verify the configuration:
   show lldp tx-tlv port {slot/port[/sub-port][-slot/port[/sub-port]][,...]}

Example

Disable the port description LLDP transmission TLV:

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)#no lldp tx-tlv port-desc

Switch:1(config-if)#show lldp tx-tlv port 1/2

Restore port description LLDP transmission TLV to the default value:

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)#default lldp tx-tlv port-desc
