Understanding SNMP basics 1 An event trap (swEventTrap, connUnitEventTrap, or swFabricWatchTrap) is basically an error message (errShow output) that is SNMP-formatted and delivered. FA traps Consider enabling the FA traps if you want to use SNMP to monitor multiple connectivity units, including Brocade switches. The switchStatusPolicySet command determines the FA-TRAP switch status-related outputs: • connUnitStatusChange • connUnitSensorStatusChange • connUnitPortStatusChange • connUnitEventTrap The MIB-II system description swEventTrapLevel determines the output for the connUnitEventTrap. Events in the Error Log of a severity at or above the configured threshold will generate SNMP traps. The Fibre Alliance Trap (FA-TRAP) can be configured to send traps using the snmpConfig command. Refer to the Fabric OS Command Reference for more information on this command. HA traps Consider enabling these traps to monitor field-replaceable unit (FRU) status and control processor (CP) status when you have a Brocade director in your environment: • fruStatusChanged This trap is generated by a FRU status change, such as a switch reboot or disabling or enabling a FRU component such as (fandisable or fanenable, etc). • cpStatusChanged This trap is generated by a change in the status of a CP, including a reboot or firmware download. • fruHistoryTrap This trap is generated when a FRU is added or removed. fruHistoryTrap is not generated when standby CP is removed. The high availability trap (HA-TRAP) can be configured to send traps using the snmpConfig command. Refer to the Fabric OS Command Reference for more information on this command. SW traps There are eleven specific traps defined in Brocade SW-TRAP. 1. swfault (no longer supported) 2. swSensorScn (no longer supported) 3. swFCPortScn This trap is generated by a port state change. 4. swEventTrap This trap is generated by any switch event reported to the system error log. Desired severity level is introduced to filter swEvent trap based on severity level. Fabric OS MIB Reference 5 53-1001768-01

Understanding SNMP basics

An event trap (swEventTrap, connUnitEventTrap, or swFabricWatchTrap) is basically an error

message (

errShow

output) that is SNMP-formatted and delivered.

FA traps

Consider enabling the FA traps if you want to use SNMP to monitor multiple connectivity units,

including Brocade switches.

The

switchStatusPolicySet

command determines the FA-TRAP switch status-related outputs:

•

connUnitStatusChange

•

connUnitSensorStatusChange

•

connUnitPortStatusChange

•

connUnitEventTrap

The MIB-II system description swEventTrapLevel determines the output for the connUnitEventTrap.

Events in the Error Log of a severity at or above the configured threshold will generate SNMP traps.

The Fibre Alliance Trap (FA-TRAP) can be configured to send traps using the

snmpConfig

command.

Refer to the

Fabric OS Command Reference

for more information on this command.

HA traps

Consider enabling these traps to monitor field-replaceable unit (FRU) status and control processor

(CP) status when you have a Brocade director in your environment:

•

fruStatusChanged

This trap is generated by a FRU status change, such as a switch reboot or disabling or enabling

a FRU component such as (fandisable or fanenable, etc).

•

cpStatusChanged

This trap is generated by a change in the status of a CP, including a reboot or firmware

download.

•

fruHistoryTrap

This trap is generated when a FRU is added or removed. fruHistoryTrap is not generated when

standby CP is removed.

The high availability trap (HA-TRAP) can be configured to send traps using the

snmpConfig

command. Refer to the

Fabric OS Command Reference

for more information on this command.

SW traps

There are eleven specific traps defined in Brocade SW-TRAP.

swfault (no longer supported)

swSensorScn (no longer supported)

swFCPortScn

This trap is generated by a port state change.

swEventTrap

This trap is generated by any switch event reported to the system error log.

Desired severity level is introduced to filter swEvent trap based on severity level.
