SNMP management station

When an unusual event, error, or a status change occurs on the device, an event notification is sent
to the SNMP management station. Fabric OS v7.0.1 supports two types of event notifications: traps
(in SNMPv1 and SNMPv3) and informs (in SNMPv3).
SNMP traps
An unsolicited message that comes to the management station from the SNMP agent on the
device is called a trap. When an event occurs and if the event severity level is at or below the set
severity level, the SNMP trap, swEventTrap, is sent to the configured trap recipients. The VarBind in
the Trap Data Unit contains the corresponding instance of the event index, time information, event
severity level, the repeat count, and description. The following are the possible severity levels:
•
•
•
•
•
•
By default, the severity level is set to None, implying all traps are filtered and therefore no event
traps are received. When the severity level is set to Informational, all traps with the severity level of
Informational, Warning, Error, and Critical are received. For more information on changing the
severity level of swEventTrap, refer to
NOTE
The Audit messages are not converted into swEventTrap.
The SNMP traps are unreliable because the trap recipient does not send any acknowledgment
when it receives a trap. Therefore, the SNMP agent cannot determine if the trap was received.
Brocade switches send traps out on UDP port 162. To receive traps, the management station IP
address must be configured on the switch. You can configure the SNMPv1 and SNMPv3 hosts to
receive the traps. For more information, refer to
For more information on the swEventTrap, refer to the Fabric OS MIB Reference.
