Fabric class areas
Table 4 lists Fabric Watch areas in the Fabric class and describes each area.
FRU class areas
Table 5 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.
Supported FRU areas depend on your particular HP switch model. The Slot and WWN areas are not
supported for the following switches:
Table 4 Fabric class sreas
Area Description
Domain ID Changes Monitors forcible domain ID changes. Forcible 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.
Fabric Logins Occurs when ports and devices initialize with the fabric.
Fabric
Reconfiguration
Tracks the number of reconfigurations of the fabric. Fabric
reconfiguration occurs when:
• Two fabrics with the same domain ID are connected.
• Two fabrics are joined.
• An E_Port has gone offline.
• A principal link has segmented from the fabric.
Loss of E_Port Tracks the number of times that an E_Port goes down. E_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 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 Digital Diagnostic SFP.
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.
