Using the Setup Utility

BIG-IP® Reference Guide 2-7

Note

For best results, choose the auto setting. In some cases, devices configured

for the auto media are incompatible, and the proper duplex setting will not

be negotiated. In these cases you may need to set the media settings to the

same speed and duplex on this device and the corresponding switch or host.

Check your switch or hub documentation for this information.

The configuration utility lists only the network interface devices that it

detects during system boot. If the utility lists only one interface device, the

network adapter may have come loose during shipping. Check the LED

indicators on the network adapters to ensure that they are working and are

connected.

Configuring VLANs and IP addresses

You can create a new VLAN or use the default internal and external VLANs

to create the BIG-IP configuration.

Determine whether you want to have security turned on for a VLAN, or off

for the VLAN. Then, type the IP address settings for the VLAN. The IP

address settings include:

• Security settings

• IP address, netmask, and broadcast

• Floating self IP address, netmask, and broadcast

We recommend that you set the floating self IP address as the default route

for target devices, such as servers. The floating self IP address is owned by

the active unit in an active/standby configuration.

Note

The IP address of the external VLAN is not the IP address of your site or

sites. The IP addresses of the sites themselves are specified by the virtual IP

addresses associated with each virtual server you configure.

Assigning interfaces to VLANs

After you configure the VLANs you want to use on the BIG-IP, you can

assign interfaces to the VLANs. If you use the default internal and external

VLANs, we recommend that you assign at least one interface to the external

VLAN, and at least one interface to the internal VLAN. The external VLAN

is the one on which the BIG-IP receives connection requests. The internal

VLAN is typically the one that is connected to the network of servers,

firewalls, or other equipment that the BIG-IP load balances.
