Configuring switch status policy 3 • Marginal One or more components are triggering a Warning alarm. • Down One or more contributors have failed. Status events are integrated into Brocade Web Tools and Fabric Manager so that if the overall status of your switch is Healthy, the switch color is green. If the overall switch status is Marginal, then the switch color is yellow. Finally, if the overall switch status is Down, the switch color is red. The overall status is calculated based on the most severe status of all contributors. NOTE Policy parameters with a value of zero are not considered when calculating the switch status. See the Web Tools Administrator's Guide for more details about configuring status events using Web Tools. 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. TABLE 15 Switch status policy monitor health factors Monitor Health factors Power Supplies Temperatures Fans WWN CP Blade Flash Marginal Ports Faulty Ports Missing SFPs Power supply thresholds detect absent or failed power supplies, and power supplies that are not in the correct slot for redundancy.

Configuring switch status policy
3
•
Marginal
One or more components are triggering a Warning alarm.
•
Down
One or more contributors have failed.
Status events are integrated into Brocade Web Tools and Fabric Manager so that if the overall
status of your switch is
Healthy
, the switch color is green. If the overall switch status is
Marginal
,
then the switch color is yellow. Finally, if the overall switch status is
Down
, the switch color is red.
The overall status is calculated based on the most severe status of all contributors.
NOTE
Policy parameters with a value of zero are not considered when calculating the switch status.
See the
Web Tools Administrator’s Guide
for more details about configuring status events using
Web Tools.
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
.
TABLE 15
Switch status policy monitor health 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 intellgent 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).
Blade
Faulty blades (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.
