Description
Use the lldp tlv-enable command to configure the types of advertisable TLVs for a port or all the ports in
a port group.
Use the undo lldp tlv-enable command to disable the advertising of specific types of TLVs.
By default, all types of LLDP TLVs, except location identification TLVs, are advertisable on a Layer 2
Ethernet port.
To enable the device to advertise LLDP-MED TLVs, you must first enable it to advertise LLDP-MED
capabilities TLVs.
To disable the device from advertising LLDP-MED capabilities TLVs, you must first disable it from
advertising other LLDP-MED TLVs.
To disable the device from advertising MAC/PHY configuration/status TLVs, you must first disable it from
advertising LLDP-MED capabilities TLVs.
If you enable the device to advertise LLDP-MED capabilities TLVs, you also enable it to advertise
MAC/PHY configuration/status TLVs.
To enable the device to advertise multiple types of TLVs, you can execute the lldp tlv-enable command
repeatedly without the all keyword specified.
