1.5.6 VLAN Function
Virtual LANs (VLANs) can be viewed as a group of devices on different physical LAN segments which
can communicate with each other as if they were all on the same physical LAN segment. It can create a
network that is independent of physical location and group users into logical workgroups. The benefits are:
_ Confine broadcast traffic and Increased performance
_ Improved manageability
_ Network tuning and simplification of software configurations
_ Physical topology independence
_ Increased security options
The switch supports port-based, 802.1Q (Tag-based) and protocol-based VLAN. In the default
configuration, VLAN function is disabled.
1.5.6.1 Port-based VLAN
Up to 26 VLAN groups can be created. Each group has its own port members. The member ports are
selected among the physical ports on the switch. Packets can go among only members in the same VLAN
group.
Required configurations:
_ Maintain (Create/delete/modify) VLAN groups
_ Manage the port members of each VLAN group
Note:
1. The ports which are not belonging to any group are treated as belonging to another single VLAN.
2. A trunk group is treated as a physical port.
3. VLAN-tagging is ignored in port-based VLAN mode.
