1 Understanding SNMP Basics 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 adding or removing a FRU component. • 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. The high availability trap (HA-TRAP) can be configured to send traps using the snmpConfig command. See the Fabric OS Command Reference for more information on this command. SW Traps There are six 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. 5. swFabricWatchTrap This trap is generated when any Fabric Watch threshold is reached. 6. swTrackChangesTrap This trap is generated by a login or a logout. The Brocade trap (SW-TRAP) can be configured to send traps using the snmpConfig command. See the Fabric OS Command Reference for more information on this command. OBJECT INSTANCES MIB objects are defined by the OID, which is the type of object, and by the instance number, which is an instance of that MIB object. A Fibre Channel port is a MIB object, and port 0 is an instance of that object. The following is an OID number and an instance number: 1.3.6.1.4.1.1588.2.1.1.1.6.2.1.11.5 where: 1.3.6.1.4.1.1588.2.1.1.1.6.2.1.11 is the OID (of swFCPortTxWords) and 5 is the instance ID for port 4. You must add 1 to the port number to get its instance number in SNMP because SNMP numbering starts at 1; switch port numbering starts at 0. 6 Fabric OS MIB Reference 53-1000439-01
