     Do any one know what cause the ISL failed, as another Brocade5000 did not have this issue.

Re: E-port invalid flow control mode in ELP

Try matching the speed, although I have just had a quick look. The flow control seems fine and its the speed and QOS which I think is causing this.

Also the long distance mode is different. set it to same.

portcfgspeed - turn this to auto neg on

portcfglongdistance - change mode to LD

portcfgqosdisable if reqd. I hate QOS.
