Areas

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.

Supported FRU areas depend on the type of Brocade switches. 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

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.

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.
