Switch status policy configuration

Switch status policy planning
Before entering the
switchStatusPolicySet
command, plan your switch status policy. Determine
your system requirements and the factors that affect its monitors.
Table 23
lists the monitors in a switch and identifies the factors that affect their health. Note that
not all switches use the listed monitors.
TABLE 23
Switch status policy factors

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.
When intelligent blades like the FR4-18i are in the 48000 chassis, the 48000 operates in
high power mode, which means that four power supplies are required for redundancy. In high
power mode, Fabric Watch assumes a policy setting of 2,1, meaning that the switch goes to a
Down state if two power supplies fail, and goes to a Marginal state when one power supply
fails. Fabric Watch automatically changes the policy setting to 2,1 when an FR-18i, FC4-16IP,
or FA4-18 blade is detected. If the blade is removed, the policy remains set to 2,1.
The presence of four or more FS8-18 encryption blades in the DCX Data Center Backbone
causes the Fabric Watch switch status policy for power supplies to assume a policy setting of
2,1, as with the blades listed above. Use the
switchstatuspolicyset
command if you need to
manually change the policy setting.
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 blade (applies to modular switches).
Flash
Flash thresholds.
Marginal Ports
Port, E_Port, optical port, and 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.
