If the above conditions are seen, it is recommended that the customer replace the SFPs and cables on the ISL in question.
When the port is disabled as an ISL, it does not change the configuration; they are not set to "no" by the software.
In order to recover from this condition, the user must remove the following commands on the ISL in question:
no fabric isl enable
no fabric trunk enable
fabric isl enable
fabric trunk enable
Simply replacing the bad media will not recover the ISL; the ISLconfigs must be toggled.
