Administrators Guide (Supporting Fabric OS v7.3.0)
Switch status policy planning
Fabric Watch monitors the health of the switch under various classes. The table below lists the current
overall switch status policy parameters in a switch and identifies the factors that affect their health. Note
that not all switches use the listed monitors.
Use the switchStatusPolicySet command to manually change the policy setting. Refer to the Fabric
OS Command Reference for more information.
NOTE
The default setting for a MARGINAL state is 0, which prevents Fabric Watch from generating
notifications due to missing power supplies. For configurations with a 2+2 power supply (PS)
combination, it is recommended that you change the default Fabric Watch default setting of 0 to 2
power supplies, which forces the overall switch status to a MARGINAL state.
Switch status policy factors TABLE 28
Monitor Health factors
Power Supplies Power supply thresholds detect absent or failed power supplies, and power supplies that are not
in the correct slot for redundancy.
Temperatures Temperature thresholds, faulty temperature sensors.
Fans Fan thresholds, faulty fans.
WWN Faulty WWN card (applies to modular switches).
CP Switch does not have a redundant CP (applies to modular switches).
Blades Faulty blades (applies to modular switches).
Core Blade Faulty core blades.
Flash Flash thresholds.
Marginal Ports Port, E_Port, FOP_Port (optical), and FCU_Port (copper) port thresholds. Whenever these
thresholds are persistently high, the port is Marginal.
Faulty Ports Hardware-related port faults.
Missing SFPs Ports that are missing SFP media.
Error Ports Ports with errors.
Brocade DCX 8510-8 default policy
The default Fabric Watch policy for the Brocade DCX 8510-8 with total power consumption of more than
2,000 watts does not properly reflect the switch status on the power supply. Fabric Watch users must
manually update the default configuration for the minimum number of power supplies to three if they
have installed more than 256 ports in a DCX 8510-8 chassis.

Marginal ports, faulty ports, error ports, and missing SFPs are calculated as a percentage of the physical ports (excluding FCoE and
VE_Ports).
