In a port-based VLAN, a VLAN name is given to a group of one or more ports on the switch.
At boot-up, all ports are members of the port-based VLAN default. Before you can add any port to another port-based VLAN, you must remove it from the default VLAN, unless the new VLAN uses a protocol other than the default protocol any. An untagged port can be a member of only one port-based VLAN.
For the members of different IP VLANs to communicate, the traffic must be routed by the switch, even if the VLANs are physically part of the same I/O module. This means that each VLAN must be configured as a router interface with a unique IP address.
