Appendix B: SNMP MIB
Overview
Simple Network Management Protocol (SNMP) Management Information Base (MIB) and SNMP
Agent software come with each BWS unit. This software lets you configure, monitor, and control units
via the Ethernet or air.
This lets you easily configure units in remote and hard-to-reach locations, and network managers
can avoid or reduce downtime by monitoring network throughput, packet collision rates, and
interference.
SNMP is a protocol used to remotely manage network elements by polling, setting terminal values,
and monitoring network statistics and events. It provides a mechanism for the exchange of
management information in a TCP/IP-based Internet environment.
The SNMP manager uses community names to determine access privileges (see Assigning
Community Names , page 52).
SNMP management software is installed on a networked PC or workstation and enables a network
administrator to remotely manage BWS systems. MIB is simply a list of objects that SNMP can
monitor.
SNMP consists of three elements: a manager, an agent and an MIB.
SNMP Element Description
Manager Is installed on the network’s host computer and is controlled by the network
administrator. From the host, the Manager configures agents, or polls agents for
information.
Agent Runs on each unit. An agent accepts configuration commands from the
manager and collects network and terminal information specified in the MIB.
Management
Information
Base (MIB) Is a database accessed by commands that you execute using the SNMP
manager. There is a standard MIB and a Wi-LAN customized MIB that stores
information relevant to the operation of a wireless network.
