Syntax

spanning-tree trap {new-root | topology-change [vlan] | errant-bpdu | root-guard-inconsistency | loop-guard-inconsistency} no spanning-tree trap {new-root|topology-change [vlan] | errant-bpdu | root-guard-inconsistency | loop-guard-inconsistency}

Description

This command enables SNMP traps for new root, topology change event, errant-bpdu received event, root-guard inconsistency, and loop-guard inconsistency notifications. It is disabled by default.

Thenoform of this command disables SNMP traps for new root and topology change event notifications.

Command context

Parameters

new-root: Enables SNMP notification when a new root is elected on any PVST vlan on the switch.
topology-change: Enables SNMP notification when a topology change event occurred in specified PVST vlan on the switch.
errant-bpdu: Enables SNMP notification when an errant bpdu is received by any PVST vlan on the switch.
root-guard-inconsistency: Enables SNMP notification when the root-guard finds the port inconsistent for any PVST vlan on the switch.
loop-guard-inconsistency: Enables SNMP notification when the loop-guard finds the port inconsistent for any PVST vlan on the switch.
