User's Manual

The levels within a MIB branch that lead to a single variable form a
pathname that is used by the following three commands to access the
variable:
Command Function
Get Display on the console the value of a MIB variable (page 7-20).
List Display on the console a variable or part of the MIB structure
[page 7-17).
Reset Reset the value of a MIB variable (to 0) (page 7-21).
Example of a Pathname to a Mib Variable
The “buf” variables shown on page 7-13 describe the router’s use of
global memory buffers. Of the four levels in this branch, the highest level
specifies the managed object, “buf”. The next lower level has only one
branch for this router, “[1]” (which, in this case, happens to be the slot
number). The next lower level distinguishes two buffer types, “msg” or
“pkt”. Multiple branches descend from each one of those buffer types
for the specific variables.
The names of the objects at each level make up a pathname for the
variable. For example, the pathname for the message buffer size variable
shown in figure 7-4 is
buf.1.msg.size
Note For a listing and description of all variables contained in the enterprise-
specific MIB on your router, refer to the Operator’s Reference.
The highest-level objects, such as ‘‘buf’’, in the “Managed Objects Table”
on page 7-14 are the first names in the pathnames used in NCL
commands. They are also branches (groups) within the Wellfleet private
enterprise branch of the standard MIB, accessible from outside the
router using SNMP functions.
The number of levels and intermediate branches is different for different
branches.
