Simple Network Management Protocol (SNMP) is a communication protocol
designed specifically for managing devices on a network. Equipment
commonly managed with SNMP includes switches, routers and host
computers. SNMP is typically used to configure these devices for proper
operation in a network environment, as well as to monitor them to evaluate
performance or detect potential problems.
Managed devices supporting SNMP contain software, which runs locally on
the device and is referred to as an agent. A defined set of variables, known
as managed objects, is maintained by the SNMP agent and used to manage
the device. These objects are defined in a Management Information Base
(MIB) that provides a standard presentation of the information controlled
by the agent. SNMP defines both the format of the MIB specifications and
the protocol used to access this information over the network.
The access point includes an onboard agent that supports SNMP versions
1, 2c, and 3 clients. This agent continuously monitors the status of the
access point, as well as the traffic passing to and from wireless clients. A
network management station can access this information using SNMP
management software that is compliant with MIB II. To implement SNMP
management, the access point must first have an IP address and subnet
mask, configured either manually or dynamically. Access to the onboard
agent using SNMP v1 and v2c is controlled by community strings. To
communicate with the access point, the management station must first
submit a valid community string for authentication.
Access to the access point using SNMP v3 provides additional security
features that cover message integrity, authentication, and encryption; as
well as controlling notifications that are sent to specified user targets.

The access point SNMP agent must be enabled to function (for versions 1,
2c, and 3 clients). Management access using SNMP v1 and v2c also
requires community strings to be configured for authentication. Trap
notifications can be enabled and sent to up to four management stations.
