The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

A router operating in layer 2 transparent mode (also called local switching) bridges two interfaces, transparently forwarding packets directly from one interface to the other. The device does not provide typical router functionality; it is sometimes referred to as operating as a “bump in the wire.”
For more information, see Layer 2 Local Switching.
AVC supports Layer 2 transparent mode scenarios, providing full AVC functionality.

For detailed information, see the configuration guide for your device.
In the following example, an AVC performance monitor is configured on a device operating in Layer 2 transparent mode. The monitor operates on the bridged traffic.
Layer 2 transparent mode (local switching) can be used to bypass a router by bridging two interfaces in the network, diverting traffic through a device operating with Cisco AVC. This enables isolation and testing of AVC functionality in the network to evaluate before wider deployment.
Layer 2 transparent mode (local switching) can be used to configure a router to act as a dedicated AVC device, used without routing. A router, such as the comparatively low-cost Cisco ASR1002-X, can serve as the platform for the standalone AVC-enabled device.
When operating AVC on a device in Layer 2 transparent mode, the following limitations apply:
