FRU monitoring

The following example shows a switch status policy for temperature:

Bad Temperatures contributing to DOWN status: (0..10) [0] 3

Bad Temperatures contributing to MARGINAL status: (0..10) [0] 1

The following example shows a switch status policy for fans:

Bad Fans contributing to DOWN status: (0..3) [0] 2

Bad Fans contributing to MARGINAL status: (0..3) [0] 1

Switch status policies are saved in a nonvolatile memory, and therefore are persistent until

changed.

Viewing your switch status policy

After you have defined and configured your switch status policy, view it with the

switchStatusPolicyShow command. The switchStatusPolicyShow command displays the following

policy parameters that determine the overall switch status.

NOTE

FCoE and VE ports are not considered in marginal port or faulty port calculations.

• Power Supplies—The power supply thresholds detect absent or failed power supplies.

• Temperature—Temperature thresholds detect faulty temperature sensors.

• Fan—Fan thresholds detect faulty fans.

• Flash—Flash thresholds monitor flash memory.

• Marginal Ports—Ports that move into the marginal state for reasons such as insufficient buffer

credits.

• Port Persistence Time—Fabric Watch waits for the port persistence time duration before it

declares the port to be in MARGINAL state when it crosses the high threshold.

• Faulty Ports—Ports that are faulty because of hardware faults, such as invalid SFPs.

• Missing SFPs—Monitors the number of ports without SFPs.

• Error Ports—Ports that are disabled because of segmentation, an authentication failure, port

fencing, or bottleneck detection.

The policy you defined determines the output in the Switch Status Policy Report.

See Chapter 10, “Fabric Watch Reports,” for more details about the Switch Status Policy Report.

FRU monitoring

Supported FRU areas depend on the type of Brocade switch. For the following switches, the slot

and WWN areas are not supported:

• Brocade 300, 5100, and 5300 switches

• Brocade DCX and DCX-4S Data Center Backbone

• Brocade Encryption Switch
