tel-number: Telephone number for urgencies, a string of 10 to 25 characters.
network-policy: Sends network policy TLVs.
power-over-ethernet: Sends extended power-via-MDI TLVs.
Description
Use the lldp tlv-enable command to enable the sending of specific TLVs for a port or all the ports in a
port group.
Use the undo lldp tlv-enable command to disable the sending of specific TLVs.
By default, all the TLVs except location identification TLVs are sent.
Note that:
To enable MED related LLDP TLV sending, you need to enable LLDP-MED capabilities TLV
sending first. Conversely, to disable LLDP-MED capabilities TLV sending, you need to disable the
sending of other MED related LLDP TLV.
To disable MAC/PHY configuration/status TLV sending, you need to disable LLDP-MED
capabilities TLV sending first.
Specifying the all keyword for basic LLDP TLVs and organization defined LLDP TLVs (including
IEEE 802.1 defined LLDP TLVs and IEEE 802.3 defined LLDP TLVs) enables sending of all the
corresponding LLDP TLVs. For MED related LLDP TLVs, the all keyword enables sending of all
the MED related LLDP TLVs except location identification TLVs.
Enabling the sending of LLDP-MED capabilities TLVs also enables the sending of MAC/PHY
configuration/status TLVs.
You can specify to send multiple types of TLVs by executing the lldp tlv-enable command
repeatedly.
