•
Authentication Failure This trap signifies that
someone has tried to logon to the switch using an invalid
SNMP community string. The switch automatically
stores the source IP address of the unauthorized user.
•
New Root This trap indicates that the Switch has
become the new root of the Spanning Tree, the trap is
sent by the switch soon after its election as the new root.
This implies that upon expiration of the Topology
Change Timer the new root trap is sent out immediately
after the Switch’s election as the new root.
•
Topology Change (STP) A Topology Change trap is
sent by the Switch when any of its configured ports
transitions from the Learning state to the Forwarding
state, or from the Forwarding state to the Blocking state.
The trap is not sent if a new root trap is sent for the
same transition.
•
Link Up This trap is sent whenever the link of a port
changes from link down to link up.
•
Link Down This trap is sent whenever the link of a
port changes from link up to link down.
MIBs
Management and counter information are stored in the Switch in
the Management Information Base (MIB). The Switch uses the
standard MIB-II Management Information Base module.
Consequently, values for MIB objects can be retrieved from any
SNMP-based network management software. In addition to the
standard MIB-II, the Switch also supports its own proprietary
enterprise MIB as an extended Management Information Base.
These MIBs may also be retrieved by specifying the MIB’s Object-
