I created 3 sub-interface (VLANS) in my internal(LAN) port. And i want to group it. Unfortunately when i click Ok, nothings happen. And there was an exclamation "One or more members are associated with an interface (VLAN-140). Only addresses that are not associated with an interface, or are associated with VLAN-140 can be added."
Please see attached screenshots.
i don't understand why i can't create this group. Please help me. Thank you!
