HP 445 manual Example of a Pathname to a Mib Variable, Buf.1.msg.size

How To Use the Network Control Language (NCL) Commands To Manage a Router

Accessing the Management Information Base

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:

CommandFunction

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
N o t e	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.
