Accessing the Management
Information Base
The router’s management information base (MIB) is the repository of all
variables gathered and used by the router, as well as accessible to the
router’s console and to other devices in the network using SNMP. The
MIB is in the form of hierarchical structure composed of managed
objects and underlying variables. This structure can be represented as
an inverted tree, such as the one shown below for the ‘‘buffers’’
information base structure.
Slot Numbers
Slot numbers are intermediate-level managed objects that appear in the
MIB structure of some objects, such as the ‘‘[1]’’ in the ‘‘buf’’ structure
shown above. For HP Series 200 and 400 routers, the slot number is
always ‘‘1’’. For HP Series 600 routers, such as the HP Router 650, the
