Work mode of port
In using VLAN, each port of switch can work in different mode. There are 2 kinds of work mode for this
series of switch: ACCESS mode and TRUNK mode.
Definition of VLAN functions are as follows:
PVID: Port Vlan ID.
TAG: VLAN Tag.
VLAN item: VID and its members
Access mode:
Exchange port under Access mode usually belongs to a VLAN as the port connecting PC.;
After Access port of switch receives Ethernet frames, it adds VLAN Tag based on port’s PVID, (if Ethernet
frames with VLAN Tag, then cover it); it depends on VLAN item whether adding VLAN Tag when Ethernet
frames send out from Access port.
Trunk mode:
Exchange port under Trunk mode can belong to several VLAN. It can send and receive several VLAN data
message. It is usually used on uplink port between switches.
After Trunk port of switch receives Ethernet frames, it needs to judge whether this Ethernet frames takes
with VLAN Tag. If so, then don’t change the VLAN Tag. If not, then add VLAN Tag of this port and transfer. It
depends on VLAN item whether frames takes with VLAN Tag when it send out from Trunk port.

VLAN Operating Method
Enter into VLAN configuration interface, according to configuration purpose, firstly select port type.
There are 2 kinds including Access and Trunk. Then set up PVID, finally add VID and its members based on
PVID. In VLAN items, the members include Unmodified, Untagged, Tagged and “---” optional.
Unmodified: refers to this port is VLAN member, the frames cannot be modified when sending out;
UnTagged: refers to this port is VLAN member, the frames are without Tag when sending out;
Tagged: refers to this port is VLAN member, the frames need to add Tag when sending out;
“---” : refers to this port is not VLAN member;
Steps for creating VLAN are as follows:
1. Enter into VLAN configuration interface, firstly select port type, Access or Trunk;
2. Enter default PVID of this port in [PVID] textbox ;
3. Enter appointed VLAN into [VID] textbox;
4. Set up members’ type of each port, like Unmodified, Untagged, Tagged
5. Click [Add
]
button, add VLAN items into list and click
[
Apply
]
and reboot the device at last. Creating new
VLAN is finished.
Steps for modifying VLAN are as follows:
This can re-configure existing VLAN including modifying member’s type and quantity of the port. Steps
are as follows:
1. Enter into VLAN configuration interface, firstly select VLAN items which need to modify in VLAN
item list, like VLAN 1;
2. Member’s type of VLAN1 shows in current VLAN item setting and set up member’s type of the port
according to the steps for creating new VLAN.
3. Click
[

]
button, select [OK] when reminds whether overwrite it as shown in Figure6.4.1. Add new
VLAN items into list and click[Apply] and reboot the device at last. Modifying VLAN finishes.
