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,

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.
SDM templates are supported only by the Metro Aggregation Services license.
Note

Router.

Auto-IP

The Auto-IP feature addresses the problem of manually reconfiguring nodes during insertion, deletion,
and movement of nodes within an auto-IP ring. The auto-IP feature automatically provides IP addresses
to the node interfaces inserted into an auto-IP ring.
For more information, see Auto-IP.

BFD Debug Enhancement

The Bidirectional Forwarding Detection (BFD) Debug Enhancement feature enhances the BFD debug
messages and the show command output and enables logs and history for critical BFD events. This
feature helps network engineers and operators to easily identify any issues with BFD sessions or events.
The following commands were introduced for this feature: monitor event-trace bfd, monitor event-trace
bfd event, monitor event-trace bfd packet, and show monitor event-trace bfd.
