An event log can be configured to send events to SNMP trap receivers by specifying an SNMP trap group destination.
An SNMP trap group can have multiple trap targets. Each trap target can have different operational parameters.
A trap destination has the following properties:
The IP address of the trap receiver.
The UDP port used to send the SNMP trap.
SNMP version (v1, v2c, or v3) used to format the SNMP notification.
SNMP community name for SNMPv1 and SNMPv2c receivers.
Security name and level for SNMPv3 trap receivers.
For SNMP traps that are sent out-of-band through the Management Ethernet port on the SF/CPM, the source IP address of the trap is the IP interface address defined on the Management Ethernet port. For SNMP traps that are sent in-band, the source IP address of the trap is the system IP address of the router.
Each trap target destination of a trap group receives the identical sequence of events as defined by the log ID and the associated sources and log filter applied. For the list of parameters sent in SNMP notifications, please see the SR OS MIBs (and RFC 3416, section 4.2.6).
