As you said, when capturing the packets on the AC, you can view the ARP packets from the POS machines to the POS server, but no reply packets are observed.

Do these ARP request packets send to the POS server, but the server doesn't reply to the request, or are the packets just discarded by the AC?

In the first case, please check the configuration on the POS server.

In the second case, please check the AC configuration.
