Thresholds

Invalid CRCs threshold

NOTE

This threshold is only available for Fabric OS devices.

Use this type of threshold to block a port when an Invalid CRCs violation meets the Fabric OS switch

threshold.

Invalid words threshold

NOTE

This threshold is only available for Fabric OS devices.

Use this type of threshold to block a port when an Invalid Words violation meets the Fabric OS

switch threshold.

Link threshold

Use this type of threshold to block a port when a Link Level (Hot I/O) error meets the threshold. A

Link Level (Hot I/O) occurs when an active loop port repeatedly receives a loop initialization

primitive sequence error or an active non-loop port repeatedly receives a line repeater, offline

sequence, or not operational sequence error.

Link Reset threshold

NOTE

This threshold is only available for Fabric OS devices.

Use this type of threshold to block a port when the link timeout errors meet the threshold.

Protocol error threshold

Use Protocol Error thresholds to block a port when one of the following protocol errors meet the

threshold:

• ISL Bouncing–ISL has repeatedly become unavailable due to link down events.

• ISL Segmentation (M-EOS only)–ISL has repeatedly become segmented.

• ISL Protocol Mismatch–ISL has been repeatedly put into the Invalid Attachment state due to a

protocol error.

State Change 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 state change violation type meets the Fabric OS

switch threshold.

For 4 Gbps Router, Extension Switches and Blades only, when you apply this threshold on an E Port,

the threshold is also applied to the VE Ports (internally by Fabric OS).
