Fabric monitoring guidelines and default settings
The Fabric class groups areas of potential problems arising between devices, including interswitch
link (ISL) details, zoning, and traffic. A Fabric class alarm alerts you to problems or potential
problems with interconnectivity.
Fabric class areas
Table 3 lists Product Name areas in the Fabric class and describes each area. Configure the Fabric
class using the thConfig command.
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 Activates when ports and devices initialize with the fabric.
Fabric reconfigure 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 goes offline.
• A principal link segments from the fabric.
E_Port downs 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).
