These parameters are displayed on the VLAN Mode Configuration page:

Port-based - 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.
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.

Segment A - The ―Segment A‖ mode is a special function for LAN
Segmentation (Converter Mode) application, it is working under
VLAN function. When the segment mode enabled, there are max.
up to 12 LAN segments on the switch and fixed two ports for each
LAN segment and each LAN segment will be isolated. The fixed
segment ports mapping as below:
