Advanced fabric diagnostic features that include:
— ISL port fencing - Any ISL that bounces (repeatedly attempts
to establish a connection) causes disruptive fabric rebuilds.
ISL fencing establishes a user-defined bounce threshold that
when reached, automatically blocks the disruptive E_Port.
— Digital SFP diagnostic support - This feature provides access
to diagnostic data generated by newer SFP optical
transceivers. The data includes temperature, transmit and
receive power, and supply voltage.
— Embedded port log - This log records all Fibre Channel traffic
sourced from or delivered to a switch's embedded port. Log
contents assist in fault diagnosis of SAN traffic problems.
— Embedded fabric log - This log records events associated
with the fabric controller, path selection, login server, and
name server. Log contents assist in fault diagnosis of fabric
problems.
