Changing one AP does not affect the configuration of other APs on the network. 
Make configuration changes to APs individually. Each AP requires an individual 
IP address.

The SNMP protocol defines the method for obtaining information about networks 
operating characteristics and changing router and gateway parameters. The SNMP 
protocol consists of three elements:

■

Management stations 

■

Management information

■

Management protocol (MIB)

Nodes can perform as hosts, routers, bridges or other devices that can 
communicate status information. An SNMP Agent is a node that runs the SNMP 
management process to systematically monitor and manage the network. The 
management station performs network management by running application 
management software.

An SNMP trap is an alert to all configured management stations of some 
significant event that occurred on the network. The management station queries 
all stations for details of each specific event, including what, when and where the 
event took place and the current status of the node or network. The format or 
structure is defined in the SNMP protocol. The MIB defines what and who 
monitors the variables.

The AP includes SNMP agent versions accessible through an SNMP manager 
application (HP Open View or Cabletron Spectrum MIB browser). The SNMP agent 
supports SNMP versions 1 and 2, MIB II, 802.11 MIB and one proprietary 3Com 
Management Information Base (MIB). The SNMP agent supports read-write, 
read-only or disabled modes. The AP supports traps that return to the SNMP 
manager when certain events occur. The Wireless LAN Installation and Utilities disk 
packaged with wireless clients contains the MIB.

The MIB defines what the management station needs to understand and which 
objects the station manages. The MIB has ten categories defined with 
approximately 175 variables.
