Re: SNMP or syslog on Spanning Tree topology changes

Under the interface, you may want to enable "logging event spanning-tree".
Please be aware that this command print a message for every status change, for every vlan. For e.g., if a trunk link has 100 vlans and it is going from blocking-->listening-->learning-->forwarding (totally 3 state changes), then the switch reports around 300 messages, 3 for each vlan.
I am not a SNMP expert. I hope, this may help you.
