Once the subtree (OID) is identified, a mask can be created to select the portions of the subtree to be
included or excluded for access using this particular view. See the
command. The view(s)
configured with this command can subsequently be used in read, write, and notify commands that are
used to assign specific access group permissions to created views and assigned to particular access
groups.
Multiple subtrees can be added or removed from a view name to tailor a view to the requirements of
the user access group.
The
no view
view-name
command removes a view and all subtrees.
The
no view
view-name
subtree
oid-value
command removes a sub-tree from the view name.
Default
no views are defined
Parameters
view-name —
the 1 to 32 character view name
Default
n/a
oid-value —
the object identifier (OID) value for the
view-name
. This value, for example,
1.3.6.1.6.3.11.2.1, combined with the mask and include and exclude statements, configures
the access available in the view.
It is possible to have a view with different subtrees with their own masks and include and
exclude statements. This allows you to customize visibility and write capabilities for specific
user requirements

Description
The mask value and the mask type, along with the
oid-value
configured in the
view
command,
determines the access of each sub-identifier of an object identifier (MIB subtree) in the view.
Each bit in the mask corresponds to a sub-identifier position; for example, the most significant bit for
the first sub-identifier, the next most significant bit for the second sub-identifier, and so on. If the bit
position on the sub-identifier is available, it can be included or excluded.
For example, the MIB subtree that represents MIB-II is 1.3.6.1.2.1. The mask that catches all MIB-II
is 0xfc or 0b11111100.
Only a single mask may be configured per view and OID value combination. If more than one entry is
configured, each subsequent entry overwrites the previous entry.
