•System inform ation
•agent n etwork address es
•Commun ity acc ess to the age nt
•SNMP trap delivery
The SNMP (the Simple Network Management Protocol) protocol is used by network
management systems and the devices they manage. SNMP is used to manage items
on the device to be managed, as well as by the device itself, to report alarm conditions
and other events.
The first version of SNMP, V1, provides the ability to to send a notification of an
event via “traps”. Traps are unacknowledged UDP messages and may be lost in
transit. SNMP V2 adds the ability to notify via “informs”. Informs simply add
acknowledgment to the trap process, resending the trap if it is not acknowledged in a
timely fashion.
