In LLDP-MED protocol, it provides extra Organizationally Specific TLVs. The TLVs lists that Pica8 switch support are as follows :

M Mandatory for this TLV to be included in all outgoing LLDP-MED LLDPDUs,

C Conditionally required, mandatory for this TLV to be included in outgoing LLDP-MED LLDPDUs under the described conditions,

Note 1: Transmission of these mandatory TLVs only applies if the associated TLV data contents have been administratively configured and apply on a given port.

Note 2: Extended Power-via-MDI TLV is mandatory for IEEE 802.3af compliant PSE Network Connectivity Devices. This TLV is not applicable for non-PoE capable ports, and should not be included in outgoing LLDP-MED LLDPDUs on such ports.

Basic Configuration: 

Enable LLDP

set protocols lldp enable true

Configure lldp med tlvs

  • basiclly these tlvs are selected by default:
set protocols lldp med-tlv-select inventory-management true/false
set protocols lldp med-tlv-select network-policy true/false
set protocols lldp med-tlv-select extended-power-via-mdi true/false
  • Configure the lldp med fast start repeat count:
  • The LLDP-MED fast start repeat count specifies the number of LLDP packets that will be sent during the LLDP-MED fast start period.
set protocols lldp med-fast-start-repeat-count 5


The LLDP MED function will only be active by receiving lldp med packets.
