1 Fabric Watch components TABLE 3 Fabric class areas (Continued) Area Description Loss of E_Port Tracks the number of times that an E_Port or VE_Port goes down. E_Ports and VE_Ports go down each time you remove a cable or an SFP (where there are SFP failures or transient errors). Segmentation Changes Tracks the cumulative number of segmentation changes. Segmentation changes occur due to: • 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. Zoning 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 Product Name 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 Slot Power Supply Fan WWN State of a slot has changed. State of a power supply has changed. State of a fan has changed. State of a WWN card has changed. Supported FRU areas depend on the type of Brocade switches. For nonmodular switches such as the Brocade 3250, 3850, 3900, 4100, 4900, 5000, 7500m and 7600, the slot and WWN areas are not supported. 6 Fabric Watch Administrator's Guide 53-0000438-01
