Fabric Watch Components 1 FRU Class Areas Table 1-4 lists Fabric Watch areas in the FRU class and describes each area. Possible states for all FRUclass areas are absent, faulty, inserted, on, off, ready, and up. Table 1-4 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 SilkWorm 3250, 3850, 3900, 4100, 4900, and 7500, the slot and WWN areas are not supported. Performance Monitor Class Areas Table 1-5 lists Fabric Watch areas in the Performance Monitor class and describes each area. Table 1-5 Performance Monitor Class Areas Area Indicates Customer Define Relies on performance monitor telnet commands. For more information on this area, see the Fabric OS Command Reference. Invalid Cyclic Redundancy Checks (CRC) Errors have been detected in the Fibre Channel frame. Invalid CRC messages occur when the number of CRC errors in Fibre Channel frames for specific source ID (S_ID) and destination ID (D_ID) pairs change. These messages can also be caused by dirty or aging equipment and temperature fluctuations. Receive Performance The percentage of word frames traveling from the configured S_ID to the D_ID exceeds the configured thresholds. Transmit Performance The percentage of word frames traveling from the configured D_ID to the S_ID; user configuration triggers these messages, so you can use the Transmit Performance area to tune your network. Port Class Areas Table 1-6 lists and describes the Fabric Watch areas in the port class. Note Fabric Watch monitors and reports the status of physical and virtual FC ports. Physical GbE ports and ISCSI ports are not monitored and are not included in the Port Class area. Fabric Watch Administrator's Guide 1-7 Publication Number: 53-1000243-01

Invalid Cyclic
Redundancy Checks
(CRC)
Errors have been detected in the Fibre Channel frame. Invalid CRC messages
occur when the number of CRC errors in Fibre Channel frames for specific
source ID (S_ID) and destination ID (D_ID) pairs change. These messages
can also be caused by dirty or aging equipment and temperature fluctuations.
Receive Performance
The percentage of word frames traveling from the configured S_ID to the
D_ID exceeds the configured thresholds.
Transmit Performance
The percentage of word frames traveling from the configured D_ID to the
S_ID; user configuration triggers these messages, so you can use the Transmit
Performance area to tune your network.
Note
Fabric Watch monitors and reports the status of physical and virtual FC ports. Physical GbE ports and
ISCSI ports are not monitored and are not included in the Port Class area.
