Description: The client's (i.e., LAN IP Device's) hardware address as indicated in the chaddr field of its DHCP REQUEST message. There is a one-to-one relationship between the hardware address and the LAN IP Device. This parameter is entered by the PS (CDP) when the CDS grants a lease to a LAN IP Device in the LAN-Trans realm and creates a row in this table. Alternatively this parameter can be created by the NMS through the CMP, when the NMS creates a new DHCP address reservation by accessing the cabhCdpLanDataAddrRowStatus object with an index comprised of a unique cabhCdpLanAddrIp and creating a row with a unique cabhCdpLanAddrClientID.
