Threshold monitoring using SNMP tables

Understanding the components of SNMP makes it possible to use third-party tools to view, browse,

and manipulate Brocade switch variables remotely. Every Brocade switch and director supports

SNMP.

When an event occurs and its severity level is at or below the set value, the Event Trap traps

(swFabricWatchTrap), are sent to configured trap recipients.

Once the switch status policy changes, Fabric Watch sends a connUnitStatusChange SNMP trap.

Any Fabric Watch RASLOG is converted into an swEventTrap.

Refer to the Fabric MIB Reference for information about the following:

• Understanding SNMP basics

• How to enable or disable the sending of traps from the various MIBs

• SNMP trap bit mask values

• Loading Brocade management information bases (MIBs)

MIB capability configuration parameters

The mibCapability option turns certain MIBs and associated SNMP traps on or off. If a specific MIB

is disabled, the corresponding traps are also disabled. If any trap group is disabled, the

corresponding individual traps are also disabled.

Refer to the SW-MIB Objects chapter of the Fabric OS MIB Reference Guide for detailed information

about the following SNMP tables that can be used to manage thresholds:

• swFwClassAreaTable

• swFwThresholdTable

Fabric Watch event settings

Fabric Watch uses two types of settings: factory default settings and user-defined custom settings.

• Factory default settings are automatically enabled. These settings vary depending on hardware

platform, and cannot be modified.

• You can create custom configurations to suit your unique environment.

You must first use the fwSetToCustom command to switch from default to custom settings, and

then use the advanced configuration options provided with the portThConfig, thConfig, and

sysMonitor commands to configure event behavior, actions, and time bases at the port level.

Use the advanced configuration option provided with the portThConfig, thConfig, and sysMonitor

commands to view and modify custom and default values for specified classes and areas in Fabric

Watch. You can customize the information reported by Fabric Watch by configuring event behavior

types, threshold values, time bases, and event settings. These area attributes are used to define

and detect events in Fabric Watch.
