SNMP v1/v2 Notification Recipients
Trap messages are generated to report system events, as defined in RFC 1215
The system can generate traps defined in the MIB that it supports
Trap receivers (aka Notification Recipients) are network nodes where the trap
messages are sent by the device A list of notification recipients are defined as
the targets of trap messages
A trap receiver entry contains the IP address of the node and the SNMP
credentials corresponding to the version that is included in the trap message
When an event arises that requires a trap message to be sent, it is sent to
every node listed in the Notification Recipient Table
The Notification Recipients SNMPv1,2 page and the Notification Recipients
SNMPv3 page enable configuring the destination to which SNMP notifications
are sent, and the types of SNMP notifications that are sent to each destination
(traps or informs) The Add/Edit pop-ups enable configuring the attributes of
the notifications
An SNMP notification is a message sent from the device to the SNMP
management station indicating that a certain event has occurred, such as a
link up/ down
It is also possible to filter certain notifications This can be done by
creating a filter in the Notification Filter page and attaching it to an SNMP
notification recipient The notification filter enables filtering the type of SNMP
notifications that are sent to the management station based on the OID of the
notification that is about to be sent
