mscVrSnmpViewMask
1.3.6.1.4.1.562.36.2.1.100.8.7.10.1.1
This attribute is the View mask which, in combination with the
corresponding instance of SnmpView subTree, defines a family of
view subtrees.
Each bit of this bit mask corresponds to a subindentifier of
SnmpView subTree, with the most significant bit of the i-th octet of
this octet string value (extended if necessary, see below)
corresponding to the (8*i - 7)-th sub-identifier, and the least
significant bit of the i-th octet of this octet string corresponding to
the (8*i)-th sub-identifier, where i is in the range 1 through 16.
Each bit of this bit mask specifies whether or not the corresponding
sub-identifiers must match when determining if an OBJECT
IDENTIFIER is in this family of view subtrees; a '1' indicates that
an exact match must occur; a '0' indicates 'wild card', meaning that
any sub-identifier value matches.
Thus, the OBJECT IDENTIFIER X of an object instance is
contained in a family of view subtrees if the following criteria are
met:
For each sub-identifier of the value of SnmpView subTree, either the
i-th bit of mask is 0, or the i-th sub-identifier of X is equal to the i-th
sub-identifier of the value of SnmpView subTree.
If the value of this bit mask is M bits long and there are more than
M sub-identifiers in the corresponding instance of SnmpView
subTree, then the bit mask is extended with 1's to be the required
length.
Note that when the value of this object is the zero-length string, this
extension rule results in a mask of all 1's being used (no wild card)
and the family of SnmpView subTrees is the one snmpView subTree
uniquely identified by the corresponding instance of subTree.
