Thresholds
22
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.
