2.4 VLAN
VLAN function provides the capability of creating virtual LAN groups for network group
management, security and performance considerations. The main purpose of setting VLAN is to
limit the traffic only flow within the port members which belong to the same VLAN group. The
traffic including broadcast packets in a VLAN group will be isolated from different groups.
This system supports both port-based VLAN and IEEE 802.1Q (tag-based) VLAN. Port-based
VLAN provides the VLAN function only for local switch. Tag-based VLAN is capable of working
with other switches to achieve the VLAN function by tagged traffic.
Just click the VLAN menu item, the VLAN Configuration page is displayed shown as blow. This
page provides the current VLAN type and the place to do advanced VLAN configuration if the
Configure button is available.
Three options of VLAN type are provided:
„
Disable – to disable VLAN function. All existing VLAN groups will be removed. PVID for all
ports will be reset.
„ Port-based VLAN – to enable port-based VLAN. All existing tag-based VLAN group will be
removed. PVID for all ports will be reset.
„ IEEE 802.1Q VLAN – to enable tag-based VLAN. All existing port-based VLAN groups will
be removed.
The VLAN type can be either port-based or tag-based. That is, both the port-based VLAN and
802.1Q VLAN can’t co-exist at the same time.
The Configure button will be enabled to click for advanced VLAN configuration only when the
current VLAN type is activated to port-based or tag-based VLAN; otherwise, this button will be
disabled.
