Chapter 20: SNMPv3
396 Section III: SNMPv3
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
