8 Switch monitoring Switch status policy planning Fabric Watch monitors the health of the switch under various classes. Table 28 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 FOS Command Reference Manual 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 suppy combination, we recommend you change the default Fabric Watch default setting of 0 to 2 power supplies (PS), which forces the overall switch status to a MARGINAL state. Brocade DCX 8510-8 default policy The default Fabric Watch policy for the Brocade DCX 8510-8 with total power consumption of more than 2000w does not properly reflect the switch status on the power supply. Fabric Watch users must manually update their default configuration for the minimum number of power supplies to three if they have installed more than 256 ports in an 8510-8 chassis. NOTE 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. Brocade 6505 default policy The default Fabric Watch policy for the Brocade 6505 is one power supply in the left bay with an optional configuration of two power supplies in both the left and right bay. The default configuration for the Brocade 6505 is a 2 (DOWN) and 0 (MARGINAL), corresponding to a one power supply configuration. If converting to a two power supply configuration, use the switchstatusPolicySet command to manually change the configuration to 2,1 for the power supply and Fan FRU units. If converting back to a one power supply configuration, use the switchstatusPolicySet command to manually change the power supply and Fan FRU units to 1,0.
