This TLV advertisement is enabled by default. To enable or disable the TLV, use this command.
Syntax
[no] lldp config
<PORT-LIST>
dot1TlvEnable port-vlan-id
Enables the VLAN ID TLV advertisement.
The no
form of the command disables the TLV advertisement.
Example
The show commands display the configuration of the TLVs. The command show lldp config
lists the TLVs advertised for each port, as shown in Example of local device LLDP information through Example of remote device LLDP information.
In the default LLDP-MED configuration, the TLVs controlled by medTlvEnable are enabled.
Syntax
[no] lldp config
<PORT-LIST>
medTlvEnable medTlv
Enables or disables advertisement of the following TLVs on the specified ports:
(Default: All of the above TLVs are enabled.)
Helps to locate configuration mismatches by allowing use of an SNMP application to compare the LLDP-MED configuration on a port with the LLDP-MED TLVs advertised by a neighbor connected to that port.

This TLV enables the switch to determine:
This TLV also enables an LLDP-MED endpoint to discover what LLDP-MED TLVs the switch port currently supports. (Default: enabled)

This TLV enables the switch port to advertise its configured network policies (voice VLAN, Layer 2 QoS, Layer 3 QoS), and allows LLDP-MED endpoint devices to autoconfigure the voice network policy advertised by the switch. This also enables the use of SNMP applications to troubleshoot statically configured endpoint network policy mismatches. (Default: Enabled)
|
||||||
|
This TLV enables the switch port to advertise its configured location data (if any.) (Default: Enabled)
|

|
This TLV enables the switch port to advertise its current PoE state and to read the PoE requirements advertised by the LLDP-MED endpoint device connected to the port. (Default: Enabled)
