For the test, I will configure on the Foxgate S6224-S4, S6224-S2, S6208, and so on.
Connect to the switch through the console or telnet and switch to the configuration mode:
Let’s create a group of isolated ports and add ports to it that do not need to see each other (in my case, clients are from 1 to 24):
isolate-port group users isolate-port group users switchport interface ethernet 1/1-24
The command is the same on all Foxgate switches, but port numbers may differ, for example on S6224-S2 I configured it like this:
isolate-port group users isolate-port group users switchport interface ethernet 0/0/1-24
After adding the ports to the group they will not see each other, but they will see the ports that are not in the group, I have the 25 port is the uplink on which the Internet comes, because it is not in the group, it sees all the ports, and the ports that the groups see him.
Let’s see the list of ports in the users group:
show isolate-port group users
Leave the configuration mode and save the settings:
