3 Areas TABLE 3 Area Fabric class areas (Continued) Description Segmentation changes Tracks the cumulative number of segmentation changes. Segmentation changes occur because of one of the following: • Zone conflicts. • Incompatible link parameters. During E_Port and VE_Port initialization, ports exchange link parameters, and incompatible parameters result in segmentation. This is a rare event. • Domain conflicts. • Segmentation of the principal link between two switches. SFP state changes Indicates whether the state of the SFP is normal or faulty, on or off. A faulty or off state means that you must reinsert, turn on, or replace the SFP. Fabric Watch monitors only the digital diagnostic SFP. Note: SFPs connected to GbE ports are not monitored. Zone changes Tracks the number of zone changes. Because zoning is a security provision, frequent zone changes might indicate a security breach or weakness. Zone change messages occur whenever there is a change in zone configurations. FRU class areas Table 4 lists Fabric Watch areas in the FRU class and describes each area. Possible states for all FRU-class areas are absent, faulty, inserted, on, off, ready, and up. TABLE 4 FRU class areas Area Indicates Fan Power Supply Slot WWN State of a fan has changed. State of a power supply has changed. State of a slot has changed. State of a WWN card has changed. Supported FRU areas depend on the type of Brocade switch. For the following switches, the slot and WWN areas are not supported: • Brocade 300, 4012, 4016, 4018, 4020, 4024, 4100, 4900, 5000, 5100, and 5300 switches • 7500, 7500E, 7600, and 7600E extension switches • Brocade DCX and DXC-4S Data Center Backbone • Brocade Encryption Switch 14 Fabric Watch Administrator's Guide 53-1001342-01
