EXPRESSION-MIB Table View

A table of expression names, for creating and deleting
expressions.

expNameEntry row .1.3.6.1.4.1.9.10.22.1.2.3.1

Information about a single expression. New expressions
can be created using expNameStatus.

To create an expression first create the named entry in this
table. Then use expExpressionIndex to populate

A table of object definitions for each expExpression.
          
Wildcarding instance IDs:
          
It is legal to omit all or part of the instance portion for
some or all of the objects in an expression. (See the
DESCRIPTION of expObjectID for details.  However, note that
if more than one object in the same expression is wildcarded
in this way, they all must be objects where that portion of
the instance is the same.  In other words, all objects may
be in the same SEQUENCE or in different SEQUENCEs but with
the same semantic index value (e.g., a value of ifIndex)
for the wildcarded portion.

expObjectEntry row .1.3.6.1.4.1.9.10.22.1.3.2.1
