Notification Recipients

Trap receivers (Notification Recipients) are network nodes to which trap messages are sent by
the device. A list of notification recipients can be defined.
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 SNMPv1.2 Notification Recipients page and the SNMPv3 Notification Recipientspage
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.
