Description: The status of a particular family of view subtrees within the particular SNMP party's MIB view. The value 'included(1)' indicates that the corresponding instances of viewSubtree and viewMask define a family of view subtrees included in the MIB view. The value 'excluded(2)' indicates that the corresponding instances of viewSubtree and viewMask define a family of view subtrees excluded from the MIB view.

Setting an instance of this object to the value 'invalid(3)' has the effect of invalidating the presence or absence of the corresponding family of view subtrees in the corresponding SNMP party's MIB view.

It is an implementation-specific matter as to whether the agent removes an invalidated entry from the table. Accordingly, management stations must be prepared to receive from agents tabular information corresponding to entries not currently in use. Proper interpretation of such entries requires examination of the relevant viewStatus object.
