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.
