Retain the VLAN identifier for VLAN transparency

You can configure a load balancing virtual server to retain the client’s VLAN identifier in packets that are to be forwarded to servers. The virtual server must be a wildcard virtual server of type ANY, and must be functioning in MAC mode.

To configure a load balancing virtual server to retain the client VLAN ID by using the CLI

At the command prompt, type the following command to configure a load balancing virtual server to retain the client VLAN ID and verify the configuration:

set lb vserver <name> -m MAC -macmodeRetainvlan ENABLED

show lb vserver <name>

Note

For a service that is bound to a virtual server on which -m MAC option is enabled, you must bind a non-user monitor.

To configure a load balancing virtual server to retain the client VLAN ID by using the GUI

  1. Navigate to Traffic Management > Load Balancing > Virtual Servers, and open a virtual server.
  2. In Advanced Settings, select Traffic Settings, and select Retain VLAN ID.
