Areas
While classes represent large groupings of information, areas represent the information that
Product Name monitors. For example, switch temperature, one of the values tracked by Fabric
Watch, is an area within the class Environment.
The tables in this section describe all of the areas monitored by Fabric Watch, organized by their
associated classes.
Environment class areas
Table 2 lists and describes the Product Name areas in the Environment class.
NOTE
The fans in the Brocade 200E do not return RPM values, so there is no fan class area for it.
Fabric class areas
Table 3 lists Product Name areas in the Fabric class and describes each area.
TABLE 2 Environment class areas
Area Description
Fan Refers to the speed of the fans inside the switch, in revolutions per minute. It is important that
the fans spin quickly enough to keep the ambient temperature from rising to levels at which
switch damage might occur.
Power Supply Monitors whether power supplies within the switch are on, off, present, absent, or faulty.
Product Name monitors power supplies to be sure that power is always available to a switch.
Temperature Refers to the ambient temperature inside the switch, in degrees Celsius. Temperature sensors
monitor the switch in case the temperature rises to levels at which damage to the switch might
occur.
TABLE 3 Fabric class areas
Area Description
Domain ID Changes Monitors forced domain ID changes. Forced 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 or VE_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 or VE_Port goes down. E_Ports and VE_Ports
go down each time you remove a cable or an SFP (where there are SFP failures or
transient errors).
