Figure 16-8 Configure TLVs of LLDP-MED Port Included TLVs Select TLVs to be included in outgoing LLDPDU. Location Identification Parameters Configure the Location Identification TLV's content in outgoing LLDPDU of the port. Emergency Number: Civic Address: Emergency number is Emergency Call Service ELIN identifier, which is used during emergency call setup to a traditional CAMA or ISDN trunk-based PSAP. The Civic address is defined to reuse the relevant sub-fields of the DHCP option for Civic Address based Location Configuration Information as specified by IETF. What: This element describes which location the DHCP entry refers to. Currently, three options are defined: the location of the DHCP server (0: DHCP server), the location of the network element believed to be closest to the client (1: Switch) or the location of the client (2: LLDP-MED Endpoint). Option (2) should be used, but may not be known. Options (0) and (1) should not be used unless it is known that the DHCP client is in close physical proximity to the server or network element. 331
