Thresholds

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).

Security threshold

NOTE

This threshold is only available for M-EOS devices.

Use this type of threshold to block a port when one of the following security violations occur:

• Authentication–the switch has repeatedly become unavailable due to authentication events.

• Fabric Binding–the switch has repeatedly become unavailable due to fabric binding events.

• Switch Binding–the switch has repeatedly become unavailable due to switch binding events.

Switch Binding is enabled through a product’s Element Manager.

• Port Binding–the switch has repeatedly become unavailable due to port binding events.

• ISL Security–(Generic Security Error) the switch on the other side of the ISL has detected a

specific security violation, but is only able to indicate that a generic security violation has

occurred or a security configuration mismatch was detected.

• N_port Connection Not Allowed–the switch has repeatedly become unavailable due to N_port

connection not allowed events.
