Brocade Fabric Watch Administrators Guide (Supporting Fabric OS v7.3.0) - Manual (Page 95)

• Flash — Flash thresholds monitor flash memory.
• Marginal Ports — Ports that move into the marginal state for reasons such as insufficient buffer
credits.
• Port Persistence Time — Fabric Watch waits for the port persistence time duration before it declares
the port to be in the MARGINAL state when it crosses the high threshold.
• Faulty Ports — Ports that are faulty because of hardware faults, such as invalid SFPs.
• Missing SFPs — Monitors the number of ports without SFPs.
• Error Ports — Ports that are disabled because of segmentation, an authentication failure, port
fencing, or bottleneck detection.
The policy you defined determines the output in the Switch Status Policy Report. Refer to Fabric Watch
Reports on page 107 for more details about the Switch Status Policy Report.
FRU monitoring
Supported FRU areas depend on the type of Brocade switch. For the following switches, the slot and
WWN areas are not supported:
• Brocade 300, 5100, and 5300 switches
• Brocade DCX and DCX-4S Data Center Backbone
• Brocade Encryption Switch
FRU class areas
The table below lists Fabric Watch areas in the FRU class and describes each area. Possible states for
all FRU-class areas are: absent or removed, faulty, inserted, on, off, ready, or up. You configure the
FRU class using the fwFruCfg command.
FRU class areas TABLE 29
Area Description
Fan State of a fan has changed.
Power supply State of a power supply has changed.
Slot State of a slot has changed.
WWN State of a WWN card has changed.
SFP State of the SFP has changed.
Configuring FRUs
The configuration of field-replaceable units (FRUs) is an exception to the procedures described
elsewhere in this document. FRUs are monitored using state values, as opposed to the quantitative
values used to monitor the rest of the fabric. As a result of the qualitative nature of this monitoring, the
concept of thresholds does not apply.
