Citrix ADC

Enable access to services when down

You can enable access to a service when it is disabled or in a DOWN state by configuring the Citrix ADC appliance to use Layer 2 mode to bridge the packets sent to the service. Normally, when requests are forwarded to services that are DOWN, the request packets are dropped. When you enable theAccess Downsetting, however, these request packets are sent directly to the load balanced servers.

For more information about Layer 2 and Layer 3 modes, seeIP Addressing.

For the appliance to bridge packets sent to the DOWN services, enable Layer 2 mode with the accessDown parameter.
