Switch policies

DRAFT: BROCADE CONFIDENTIAL
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” for information on viewing the current switch
policies using the switch policy report.
Audit messages
Fabric Watch events caused by configuration value changes are tagged as Audit messages.
NOTE
Audit messages are generated for port fencing configuration changes, whether port fencing is
enabled or disabled.
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.
