Deployment Guide

Refer to Fabric Watch reports on page 107 for information on viewing the current switch policies using
the Switch Status Policy report.
Logical switch support
Fabric Watch can monitor the switch health on eight logical switches. You can configure thresholds and
notifications for ports that belong to a particular logical switch. Each logical switch has its own Fabric
Watch configuration and triggers notifications based on its local configuration.
Fabric Watch supports port movement from one logical switch to another. Whenever a port is moved,
thresholds associated with the port are deleted from the logical switch from which the port was moved,
and created for the logical switch to where the port is moved.
On logical interswitch links (LISLs), Fabric Watch supports state change notifications in the same
manner as for normal E_Ports and uses the same threshold values for LISLs as for E_Ports, but does
not support threshold areas such as link loss or signal loss.
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, and
any existing Fabric Watch RASLog is converted into an swEventTrap.
Refer to the Fabric OS release notes, the Fabric OS Administrator's Guide, and the MIB files
themselves for information about the following:
• Understanding SNMP basics
• How to enable or disable the sending of traps from the various MIBs
• SNMP trap bitmask 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 Fabric OS release notes, the Fabric OS Administrator's Guide, and the MIB files
themselves for detailed information about the following SNMP tables that can be used to manage
thresholds:
• swFwClassAreaTable
• swFwThresholdTable
