I've set up 7 RFID readers on our network. They are generating more traffic than normal as I am polling them one a second to grab any RFID tags they may have read.
All of a sudden, after 15 hours or so, all readers stopped working with a "socket" issue.
All readers have a static IP address and operate on the same subnet as the reset of the network.
I though that maybe our firewall detected this extra activity and, perhaps, shut down the ports. I reached out to our firewall people and they said that this wouldn't be a firewall issue as this is all internal traffic.
I changed the IP address of one of the readers and it started working again. Changed it back and it quit.
The firewall people stated "This would be more so pointing to the switch than the firewall as all local broadcast traffic takes place on the switch and would't be touching the firewall. You may check in to broadcast storm or some kind of switch setting that would be dropping the traffic. You may even consider peeling this system out on to its own network / interface and decrease the size of the broadcast domain to help improve performance. Hope this helps steer you in the right direction."
The switch shows "Ingress Control Mode", under Storm Control, as Disabled.
Any thoughts here?
