Using SNMP Version 1, the network manager can issue three types of com-
mands:

•

:  This command retrieves a single item or the first in a series 

from a network device.

•

:  This command retrieves the next item in a series from 

a network device.

•

: This command writes information to a network device.

The network device issues two types of messages:

•

:  This message is the response to a network manager GetRe-

 or GetNextRequest command.

•

:  This is an unsolicited message issued by a network device to report 

an operational anomaly or an alarm condition to the network manager.

These messages are typically encased within informational packets and trans-
ported over the LAN or WAN.
