Port isolation?

Dear community,


We have a Customer installed with DS-300B switches, HP servers with Qlogic HBAs and EMC² VNX storage.

Recently we had an issue there, where the whole fabric was impacted, slowing down quite a bit. We investigated and found out that an optical cable was faulty. The fabric went up normally after the cable change.


Here's my question :  is there a port isolation technique that can be activated in the DS-300B?

Generally speaking,  is there a way we prevent a simple faulty cable to bring the fabric down?


Thanks in advance for your help.

Re: Port isolation?



use port fencing - assuming MAPS - to disable the port on CRC as in this example.
