In Software Release 3.0.5, the command interface for managing SNMP
traps has changed and new features have been added for filtering

traps.
These trap filters are available:

link state trap when one of its configured ports transitions from the
Up state to the Down state, or from the Down state to the Up state.
„ set snmp trap filter topology_change
Enables or disables the generation of topology change traps, which
are sent by a bridge when one of its ports moves from the Learning
State to the Forwarding state, or from the Forwarding state to the
Blocking state.
