Trap Filtering
In Software Release 3.0.5, the command interface for managing SNMP
traps has changed and new features have been added for filtering
(enabling or disabling) link state, topology change, and authentication
traps.
Available Trap Filters These trap filters are available:
„ set snmp trap filter link_state
Enables or disables the generation of link state traps. A bridge sends a
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.
The trap is not sent if a
newRoot
trap is sent for the same transition. If
you disable topology change traps, you will still see
newRoot
traps
which indicate that the sending agent has become the new root of
the Spanning Tree.
„ set snmp trap filter authentication
Enables or disables the feature that sends an alert to the management
workstation when someone tries to gain access to the EME, and the IP
address or community name is not valid for the attempted read or
write operation.
Managing Traps In Software Release 3.0.5, the command interface for managing SNMP
traps has changed. These commands are affected:
„ set snmp trap
„ show snmp
„ clear snmp
