This is an optional parameter that is used to further refine the
value in the View Subtree parameter. This parameter is in binary
format.
A subtree mask and a subtree have a similar relationship as an IP
address and a subnet mask. The subnet mask further refines the IP
address. In the same way, the OID table entry defines a MIB View
and the subtree mask further restricts a user’s view to a specific
the column and row of the MIB View. The value of the Subnet
Mask parameter is dependent on the subtree you select. For
example, if you configure the View Subtree parameter as MIB,
ifEntry.0.3 has the following value:
1.3.6.1.2.1.2.2.1.0.3
To restrict the user’s view to the third row (all columns) of the
ifEntry MIB, enter the following value for the Subtree Mask
parameter:
ff:bf
