The name of the expression. Choosing names with useful
lexical ordering supports using GetNext or GetBulk to
retrieve a useful subset of the table.

Open in standard view 
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 entry .1.3.6.1.4.1.9.10.22.1.3.2.1
