Displaying SNMP Status
SNMP is an application-layer protocol that provides a message format for
communication between SNMP managers and agents. The SNMP manager can
be part of a network management system (NMS) such as CiscoWorks. The agent
and management information base (MIB) reside on the access point. To
configure SNMP on the access point, you define the relationship between the
manager and the agent.
The SNMP agent contains MIB variables whose values the SNMP manager can
request or change. A manager can get a value from an agent or store a value into
the agent. The agent gathers data from the MIB, the repository for information
about device parameters and network data. The agent can also respond to a
manager's requests to get or set data.
An agent can send unsolicited traps to the manager. Traps are messages alerting
the SNMP manager to a condition on the network. Traps can mean improper
user authentication, restarts, link status (up or down), MAC address tracking,
closing of a TCP connection, loss of connection to a neighbor, or other
significant events.
