Switch monitoring

Before entering the switchStatusPolicySet command, plan your switch status policy. Determine
your system requirements and the factors that affect its monitors.

lists the monitors in a switch and identifies the factors that affect their health. Note that

Health factors
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.
Temperature thresholds, faulty temperature sensors.
Fan thresholds, faulty fans.
Faulty WWN card (applies to modular switches).
Switch does not have a redundant CP (applies to modular switches).
Faulty blades (applies to modular switches).
Flash thresholds.
Port, E_Port, FOP_port (optical), and FCU_Port (copper) port thresholds. Whenever these
thresholds are persistently high, the port is Marginal.
Hardware-related port faults.
Ports that are missing SFP media.
