Enabling SNMP notifications for new-root election
and topology change events
This task enables the device to generate logs and report new-root election events or spanning tree
topology changes to SNMP. For the event notifications to be sent correctly, you must also configure
SNMP on the device. For more information about SNMP configuration, see the network
management and monitoring configuration guide for the device.
When you use the snmp-agent trap enable stp [ new-root | tc ] command, follow these guidelines:
• The new-root keyword applies only to STP, MSTP, and RSTP modes.
• The tc keyword applies only to PVST mode.
• In STP, MSTP, or RSTP mode, the snmp-agent trap enable stp command enables SNMP
notifications for new-root election events.
• In PVST mode, the snmp-agent trap enable stp enables SNMP notifications for spanning tree
topology changes.
