Port-based:

Fig. 3-17

Port-based VLAN is defined by port. Any packet coming in or outgoing
from any one port of a port-based VLAN will be accepted. No filtering
criterion applies in port-based VLAN. The only criterion is the physical
port you connect to. For example, for a port-based VLAN named
PVLAN-1 contains port members Port 1&2&3&4. If you are on the port
1, you can communicate with port 2&3&4. If you are on the port 5, then
you cannot talk to them. Each port-based VLAN you built up must be
assigned a group name. This switch can support up to maximal 24 port-
based VLAN groups.

Tag-based:

Tag-based VLAN identifies its member by VID. This is quite different
from port-based VLAN. If there are any more rules in ingress filtering list
or egress filtering list, the packet will be screened with more filtering
criteria to determine if it can be forwarded. The switch supports
supplement of 802.1q. For more details, please see the section VLAN
in Chapter 3.

Each tag-based VLAN you built up must be assigned VLAN name and
VLAN ID. Valid VLAN ID is 1-4094. User can create total up to 4094
Tag VLAN groups.
