Chapter 9: AT-MUX Multiple VLAN Protocol
160
To adjust the properties of a VLAN connection, you must use the
corresponding tagged VLAN connection icon. Since each VLAN is
considered a separate connection, you can adjust the properties
individually.
This is illustrated in Figure 92 on page 161. The figure shows the Network
Connections window with three LAN connections, one for the adapter and
two others for tagged VLANs. The figure shows the properties windows for
the network adapter card and the first VLAN connection. Note that the
Properties window for the card’s connection has only the AT-MUX protocol
selected and all others deselected, while the reverse is true for the
Properties window of the tagged VLAN connection.
Each VLAN must be assigned a unique IP address. All of the addresses of
the VLANs of a network adapter card must belong to the same subnet.
Consequently, the network portion of the IP addresses must be the same
for all the addresses and they must all share the same subnet mask. For
instructions on how to set the IP configuration, refer to “Configuring the IP
Address, Subnet Mask, and Gateway Address” on page 92.
Planning is essential to using the AT-MUX protocol. This should include
determining the VIDs of the VLANs you want to add to the card. You
should also select IP addresses and a subnet mask. Of course, you can
activate DHCP client on the VLAN connections and have a BOOTP or
DHCP server assign the IP addresses and subnet mask automatically.
Creating a table similar to the following can help in implementing the
feature.
