SNMP Management
SNMP is a transmission control protocol/internet protocol (TCP/IP) that uses the user
datagram protocol (UDP) or other protocols such as UDP/IP to exchange messages
between an SNMP agent (in a managed device) and a management station residing on a
network. Since SNMP does not rely on the underlying communication protocols, it can be
made available over other protocols.
A MIB is a hierarchical tree of groups and variables. Operators at a network management
station enter a command with supported groups and variables from the MIB. Each group
is a "branch" and each variable is a "leaf" within the MIB tree. The tree begins with the
root. The MIB for the director is under the iso branch (refer to Figure 3). To get to the
director MIB variables, you must go through the org, dod, and internet sub-branches.
