Switch Policies

Switch policies are a series of rules that define specific states for the overall switch. Fabric OS interacts

with Fabric Watch using these policies. Each rule defines the number of types of errors that transitions

the overall switch state into a state that is not healthy. For example, you can specify a switch policy so

that if a switch has two port failures, it is considered to be in a marginal state; if it has four failures, it is

in a down state.

You can define these rules for a number of classes and field replaceable units, including ports, power

supplies, flash memory, and fans.

See Chapter 4, “Generating Fabric Watch Reports” to view the current switch policies using the switch

policy report.

Interpreting Event Messages

Fabric Watch events caused by configuration value changes are tagged as Audit messages. You can set

up an external host to receive Audit messages so you can easily monitor unexpected changes. For

information on error messages generated by Fabric Watch, see the Fabric OS Message Reference. For

information on configuring an Audit Log, see the Fabric OS Administrator’s Guide.
