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:

• None (0)

• Critical (1)

• Error (2)

• Warning (3)

• Informational (4)

• Debug (5)

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 “Changing the severity level of swEventTrap” on page 11.

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 “Configuring the SNMP server hosts” on page 7.

For more information on the swEventTrap, refer to the Fabric OS MIB Reference.
