Each row represents a host (or set of hosts) that is unmatched. Objects tmnxLocUsrDbMatchTypeDhcp1, tmnxLocUsrDbMatchTypeDhcp2, tmnxLocUsrDbMatchTypeDhcp3 and tmnxLocUsrDbMatchTypeDhcp4 specify which objects in the tmnxLocUsrDbDhcpTable are used to match the DHCP parameters against. This table has entries for each host in the tmnxLocUsrDbDhcpTable that: - has no objects configured that correspond with the match types, or - has identical values configured for the objects that correspond with the match types, as another PPPoE host. Entries in this table cannot be created or deleted via SNMP operations.
