I have an Juniper EX3400-24P switch at a site that runs 5 Infinias door controllers. And for some reason the door controllers will lose connectivity to the server. But the ports on the switch still show as being active. I have 62 doors on the same brand and type of switches at other locations and this is the only one that is having a problem and being that all 5 doors at this location is having an issue, it leads me to believe that the switch is the problem. I just don't know where to look. Any one have any ideas?
