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 switch. A list of trap receivers is 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 will be 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 trap receiver list.

The SNMPv1,2 Notification Recipient page and the SNMPv3 Notification Recipient 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 switch 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.
