This trap is sent by the AP when any of its configured ports transitions from the
Learning state to the Forwarding state, or from the Forwarding state to the
Blocking state.
This trap is not sent if a newRoot trap is sent for the same transition.
Trap Severity Level: Informational
All these alarm groups correspond to System Alarms that are displayed in the
screen, including the
traps that are sent by the AP to the SNMP managers specified in the
Severity Levels
There are three severity levels for system alarms:
–
Critical
–
Major
–
Informational
Critical alarms will often result in severe disruption in network activity or an automatic reboot of the AP.
Major alarms are usually activated due to a breach in the security of the system. Clients cannot be authenticated or an
attempt at unauthorized access into the AP has been detected.
Informational alarms are there to provide the network administrator with some general information about the activities
the AP is performing.
