Hi,
I have an HP 1920 with 24 ports. There is an up stream firewall/router connected to port 24 and endpoints connected to ports 1, 17, 21 and 23. This is confirmed in the Device > Interface Stastics web page.
However, when I view the Network > ARP Management web page, I see a MAC address for 1 endpoint connected to Port 1. All other Mac addresses (there are 7) seemingly connected to Port 24.
I appreciate there are more MAC addresses than physically connected ports, as some of the enpoints are running VM's. However, I don't understand why ARP is showing them all connected to Port 24 - the firewall.
How is this?
Thanks in advance.
