MIB

This is an index to the organized data within a network device. It defines the operating parameters that can be controlled or moni- tored. When requesting the network manager to retrieve or modify a particular piece of information about a network device, the net- work manager transmits the request to that network device. The agent in that device interprets the incoming request, performs the requested task, and sends its response to the network manager. The network manager collects all the data from the various net- work devices and presents it in a consistent form.

COMMAND S

Using SNMP Version 1, the network manager can issue three types of commands: GetRequest, GetNextRequest, and SetRequest.

GetRequest

This command retrieves a single item or the first in a series from a network device.

GetNextRequest

This command retrieves the next item in a series from a network device.

SetRequest

This command writes information to a network device.
