Preparing for VLAN Configuration
A little forethought and planning is essential to a good VLAN implementation. Before attempting
to configure a single switch for VLAN operation, consider the following:
How many VLANs will be required
What stations will belong to them
What ports are connected to those stations
What ports will be configured as GARP-aware ports
It may also be helpful to sketch out a diagram of your VLAN strategy. The examples provided in
Chapter 4 may be useful for a depiction of the planning process.
Access Local Management as described in your device user’s guide. Perform all required initial
setup operations. Navigate to the 802.1Q VLAN Configuration Menu screen to begin the VLAN
configuration process for the device.
3.3 802.1Q VLAN CONFIGURATION MENU SCREEN
When to Use
To select screens to assign switched network ports to VLANs, define new VLANs, and configure
port filtering according to a VLAN list or untagged frames. Network users can be logically
grouped into VLANs even if they span long physical distances over a vast, intricate physical
network. The VLAN Local Management menu items listed on the 802.1Q VLAN Configuration
Menu allow such VLANs to be configured on a network at the switched port of the device or
SmartSwitch chassis. Also, some or all of the ports on the switch can be configured as GVRP
ports, which enable frames received with a particular VLAN ID and protocol to be transmitted on
a limited number of ports. This keeps the traffic associated with a particular VLAN and protocol to
be isolated from the other parts of the network.
Before attempting the VLAN configuration, ensure that the device to be configured has been set
for 802.1Q SWITCHING mode. The mode selection is a Local Management operation that is
accessible through the General Configuration screen of the device.
CAUTION: The device resets when changing operational modes.
