2. Define the VLANs.
In this configuration, set up two VLANs: One for the outside world (the ports connected to the
upstream switches, toward the routers) and one for the inside (the ports connected to the down-
stream switches, toward the servers).
Repeat this command for the second VLAN.
n
VLAN 1 - IF 5—physical ports connected to upstream switches.
n
VLAN 2 - IFs 1,2,3,4—physical ports connected to downstream switches.
3. Disable Spanning Tree.
4. Enable IP forwarding.
IP forwarding is enabled by default. Make sure IP forwarding is enabled if the virtual server IP
addresses and real server IP addresses are on different subnets, or if the switch is connected to
different subnets and those subnets need to communicate through the switch. If you are in
doubt as to whether or not to enable IP forwarding, enable it. In this example, the virtual server
IP addresses and real server IP addresses are on different subnets, so enable this feature using
the following command:
>> Main# /cfg/vlan < VLAN number > (Select VLAN 1)
>> vlan 1 # add < port number > (Add a port to the VLAN membership)
>> vlan 1 # ena (Enable VLAN 1)
>> Main# /cfg/stp 1 (Select the STP Group number)
>> Main# /cfg/stp/off (Disable STP)
>> Main# /cfg/stp/apply (Make your changes active)
>> Main# /cfg/ip/frwd/on (Enable IP forwarding)
