Notification methods 1 Fabric Watch uses port persistence for a port event that requires the transition of the port into a marginal status. Fabric Watch does not record any event until the event persists for a length of time equal to the port persistence time. If the port returns to normal boundaries before the port persistence time elapses, Fabric Watch does not record any event. The port persistence time is measured in seconds, and can be configured. Configuring the port persistence time to zero disables this feature. The default value for port persistence is 18 seconds. Notification methods There are five notification methods available through Fabric Watch, but not all notification methods can be applied to all of the classes. Valid notification methods are represented through the valid alarm matrix. Fabric Watch provides the following notification methods: • "Switch event (error) log entry," next • "SNMP trap" on page 19 • "RAPI trap" on page 20 • "Port log lock" on page 20 • "E-mail alert" on page 20 To enable event settings, you must set the associated attribute to a nonzero value between 1 and 31. The exact value you specify determines which event notification method Fabric Watch uses if the event setting criteria is met. For details about valid notification methods in the alarm matrix, see "Assigning notification methods" on page 21. SWITCH EVENT (ERROR) LOG ENTRY The switch event (error) log holds up to 1024 entries. This error log stores event information but does not actively send alerts. Use the errShow command to view the log. Log entries can also trigger SNMP traps if the SNMP agent is configured. When the SNMP agent is configured to a specific error message level, then error messages at that level trigger SNMP traps. For information on configuring the SNMP agent using the agtCfgSet command, see the Fabric OS Command Reference. SNMP TRAP The Simple Network Management Protocol (SNMP) performs an operation called a trap that notifies a management station (a workstation that runs network management applications using SNMP protocol) when events occur. You must configure the software to receive trap information from the network device. You must also configure the SNMP agent on the switch to send the trap to the management station using the agtCfgSet command. For more information on this command, see the Fabric OS Command Reference. An SNMP trap forwards the following information to an SNMP management station: • Name of the element whose counter registered an event Fabric Watch Administrator's Guide 19 53-0000438-01
