1.11 Enabling Trap Messages Conforming to 802.1d
Standard
When enabled, the switch sends the following two types of 802.1d-compliant traps to
the network management device:
z
When the switch is configured to be the root bridge of a spanning tree instance, it
sends 802.1d-compliant newroot traps to the network management device.
z
When the switch detects a topology change, it sends 802.1d-compliant
topology-change traps to the network management device.
The
