I have a pair of Brocade switches with ISLs running between them. I'd like to know if it's possible to be alerted when one of the ISL ports goes from an E_PORT to anything else (particularly a U_PORT). I am about to write a /sh script on a management box that will run a portshow command every 15 minutes and email me if it doesn't see what I need it to, but there has to be an easier way. How do you monitor your ISL ports?
Use snmpwalk and monitor
