Thresholds

NOTE

Fabric OS devices are allowed only 2 defined thresholds (one default and one custom) foe each

threshold type and only one of these thresholds can be active on the device.

During the dynamic operation of a Fabric, any port could be any type. For example, a technician

could disconnect a port from a switch and reconnect that port to a storage port, or the port could

change from an E_port to an F_port. Therefore, when calculating the Affected Ports value the

Management application does not look for the current port type, but looks at the policy priority level

in relation to the other policies currently assigned to this switch.

When there are two or more policies on a switch, the total number of Affected Ports may be more

than the total number of ports on the switch (the same port may adopt different policies depending

on changes in the port’s port type).

For default threshold values for Fabric OS devices, refer to Chapter 7 of the Fabric Watch

Administrator's Guide.

C3 Discard Frames threshold

NOTE

This threshold is only available for Fabric OS devices running 6.3 or later.

Use this type of threshold to block a port when a C3 Discard Frames violation meets the Fabric OS

switch threshold. This threshold is only supported on the following devices:

• 40-port, 8 Gbps FC Switch

• 80-port, 8 Gbps FC Switch

• 8 Gbps 12-port Embedded Switch

• 8 Gbps 24-port Embedded Switch

• 8 Gbps 16-port Embedded Switch

• 8 Gbps 24-port Embedded Switch

• 8 Gbps 16-FC-ports, 10 GbE 8-Ethernet Port Switch

• 384-port Backbone Chassis

• 192-port Backbone Chassis

• 8 Gbps Encryption Switch

• Encryption Blade

• FC 8 GB 16-port Blade

• FC 8 GB 32-port Blade

• FC 8 GB 48-port Blade
