BIG-IP Link Controller
Overview: Web hosting multiple customers using an external switch
You can use the BIG-IP system to provide hosting services, including application delivery, for multiple customers.
To host multiple web customers, you can incorporate an external switch into the configurations. In this illustration, the BIG-IP system has an interface (5.1) assigned to three VLANs on a network. The three VLANs are vlanA, vlanB, and vlanB. Interface 5.1 processes traffic for all three VLANs. Note that each VLAN contains two servers, and serves a specific customer.

Creating a VLAN with a tagged interface
- On the Main tab, click The VLAN List screen opens. .
- Click Create. The New VLAN screen opens.
- In the Name field, type a unique name for the VLAN.
- In the Tag field, type a numeric tag, from 1-4094, for the VLAN, or leave the field blank if you want the BIG-IP system to automatically assign a VLAN tag. The VLAN tag identifies the traffic from hosts in the associated VLAN.
- For the Interfaces setting, click an interface number or trunk name from the Available list, and use the Move button to add the selected interface or trunk to the Tagged list. Repeat this step as necessary. You can use the same interface for other VLANs later, if you always assign the interface as a tagged interface.
- If you want the system to verify that the return route to an initial packet is the same VLAN from which the packet originated, select the Source Check check box.
- In the MTU field, retain the default number of bytes (1500).
- From the Configuration list, select Advanced.
- If you want to base redundant-system failover on VLAN-related events, select the Fail-safe box.
- From the Auto Last Hop list, select a value.
- From the CMP Hash list, select a value.
- To enable the DAG Round Robin setting, select the check box.
- Click Finished. The screen refreshes, and displays the new VLAN from the list.

For the Priority Group Activation setting, specify how
to handle priority groups:
- Select Disabled to disable priority groups. This is the default option.
- Select Less than, and in the Available Members field type the minimum number of members that must remain available in each priority group in order for traffic to remain confined to that group.
Using the New Members setting, add each resource that
you want to include in the pool:

- Type a port number in the Service Port field, or select a service name from the list.
- To specify a priority group, type a priority number in the Priority Group Activation field.
- Click Add.
- Click Finished.
Creating a virtual server for HTTP traffic
- On the Main tab, click The Virtual Server List screen opens. .
- Click the Create button. The New Virtual Server screen opens.
- In the Name field, type a unique name for the virtual server.
- For the Destination setting, in the Address field, type the IP address you want to use for the virtual server. The IP address you type must be available and not in the loopback network.
