This value controls whether a DHCP relay agent table entry is active or scheduled for removal, similar in purpose to a standard row-status control though using this device's own two-value convention rather than the standard RowStatus enumeration. An admin sets this to invalid(1) to retire an old relay agent entry, which gets deleted from the table after the next device reset, or leaves it at valid(2) to keep the entry active. For example, marking an obsolete relay agent entry as invalid(1) and then reloading the device removes that entry from the configuration.
