Message

The network device issues two types of messages:

GetResponse

The response to a network manager

EQUEST

EXT

EQUEST

command.

Trap

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 informa-
tional packets and transported over the LAN or WAN
(wide area network).
