Notification Recipients

Cisco Small Business 200, 300 and 500 Series Managed Switch Administration Guide (Internal Version) 

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.

To define a recipient in SNMPv1,2:
