Enabling SNMP notifications for BGP
This feature enables generating SNMP notifications for BGP upon neighbor state changes, as defined in
RFC 4273. The SNMP notifications include the neighbor address, the code and subcode of the most
recent error, and the current neighbor state. The generated SNMP notifications are sent to the SNMP
module. The SNMP module determines how to output the notifications according to the configured output
rules.
For more information about SNMP notifications, see Network Management and Monitoring
Configuration Guide.

Enabling logging of session state changes
Perform this task to enable BGP to log BGP session establishment and disconnection events. To view the
log information, use the display bgp peer ipv4 unicast log-info command or the display bgp peer ipv6
unicast log-info command. The logs are sent to the information center. The output rules of the logs
(whether to output the logs and where to output) are determined by the information center configuration.
For more information about information center configuration, see Network Management and Monitoring
Configuration Guide.
