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.
NOTE: See Chapter 5, to view the current switch policies using the switch policy report.
