Thresholds

Thresholds
You can create thresholds, which you can then assign to available objects in the tree. Port Fencing
threshold types include the following:
•
•
•
•
•
•
•
•
NOTE
You can create up to 16 thresholds for M-EOS devices.
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.
NOTE
The C3 Discard Frames threshold cannot be applied to an E port.
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:
