Access Circuit Redundancy
Access Circuit Redundancy (ACR) enables local switching for circuit emulation (CEM) interfaces by
creating a virtual CEM-ACR interface. All configuration changes made on the virtual CEM-ACR
interface are applied automatically on both the Working and Protect interfaces.
For more information see, Configuring Access Circuit Redundancy on the Cisco ASR 903 Router .
Access Switch Device Manager Template
The Switch Device Manager (SDM) templates are used to optimize system resources in the router to
support specific features, depending on how the router is used in the network. The SDM templates
allocate Ternary Content Addressable Memory (TCAM) resources to support different features.
Note
SDM templates are supported only by the Metro Aggregation Services license.

Router.
