Configuring switch status policy
3
Step 1: Plan and define your switch status policy
Before entering the switchStatusPolicySet command, plan your switch status policy. How many
fans must fail before you consider a switch Marginal? Look at the needs of your system along with
the factors that affect its monitors. Table 15 lists the monitors in a switch and identifies the factors
that affect their health. Note that not all switches use the monitors listed in Table 15.
Step 2: Implement your switch status policy
After planning and defining your switch status policy, enter the switchStatusPolicySet command to
configure each policy. Each policy has two parameters that can be configured: Marginal and Down.
Set the number of units Marginal or Down based on your system requirements for each
policy/parameter. 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 non volatile memory, and therefore are persistent until
changed.

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.
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 blade is detected. If the blade is removed, the policy remains set to 2,1.
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.
