Using Fabric Watch Table 6 lists Fabric Watch areas in the fabric class and provides a description of each area. Table 6: Fabric-Class Areas Area E_Port downs fabric reconfigure domain ID changes segmentation changes zone changes fabric logins SFP state changes Description Tracks the number of times that an E_Port goes down. E_Ports go down each time you remove a cable or SFP. SFP failures also cause E_Ports to go down. E_Port downs may also be caused by transient errors. Indicates reconfigurations of the fabric. The following occurrences can cause a fabric reconfiguration: ■ Two fabrics with the same domain ID have connected to one another. ■ Two fabrics have joined. ■ An E_Port has gone offline. ■ A principal link has segmented from the fabric. Indicates a Domain ID change. Domain ID changes occur when there is a conflict of domain IDs in a single fabric and the principal switch has to assign another domain ID to a switch. Tracks the cumulative number of segmentation changes. Segmentation changes may occur due to ■ Zone conflicts. ■ Incompatible link parameters. During E_Port initialization, ports exchange link parameters. Incompatible parameters result in segmentation. This incompatibility rarely occurs. ■ Domain conflicts. ■ Segmentation of the principal link between two switches. Tracks number of zone changes. Keeps the user appraised on how frequently they change zones. Because zoning is a security provision, frequent zone changes probably mean a security breach or weakness. Zone change messages occur whenever there is a change in zone configurations. Fabric login messages occur when ports/devices initialize with the fabric. Indicates whether the state of the SFP is normal or faulty, on or off. A faulty or off state indicates that you must re-insert, turn on, or replace the SFP.
