An incoming string of the type that corresponds to the value of the tmnxLocUsrDbDhcpMaskMatchType index of this conceptual row is matched with the object in the tmnxLocUsrDbDhcpTable that corresponds to the values of the tmnxLocUsrDbUserDatabaseName and tmnxLocUsrDbDhcpMaskMatchType indices in this conceptual row: match type | object circuitId | tmnxLocUsrDbDhcpCircuitId macAddr | tmnxLocUsrDbDhcpMacAddress remoteId | tmnxLocUsrDbDhcpRemoteId sapId | tmnxLocUsrDbDhcpSapId serviceId | tmnxLocUsrDbDhcpServiceId string | tmnxLocUsrDbDhcpString systemId | tmnxLocUsrDbDhcpSystemId option60 | tmnxLocUsrDbDhcpOption60
