I’m using a CSS326-24G-2S+ with SwOS 2.16 and i’m not seeing any port enumerated under the host tab. I’m getting mac addreses, vlan but no ports are listed ?
The port listed is the port name - not the port number. Do you by chance have no name listed on the “Link” page?
Here is one of my CSS326 switches with SwOS 2.16

Ah mannn a feel so stupid, thanks !
Don’t feel stupid. It actually would make sense to use the port number if there is no name. I put names on every port because it helps me remember stuff. Also useful on the VLANs page where the name will show up when you rest the cursor over a checkbox. Helps avoid clicking the wrong box.
