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
