1 port OC-48/STM-16 or 4 port OC-12/OC-3 / STM-1/STM-4 + 12 port T1/E1 + 4 port T3/E3 CEM Interface Module

Unframed Framing Support on E1 and Channel STM links

In this release, a new framing mode unframed is supported for the 1 port OC-48/STM-16 or 4 port OC-12/OC-3 / STM-1/STM-4 + 12 port T1/E1 + 4 port T3/E3 CEM Interface Module. With the unframed mode, you can create serial interface under the SDH VC12 mode.

Carrier Ethernet

CFM Sessions Hardware Offload

This feature enables for effective CPU utilization by offloading the one second CCM interval sessions on the hardware.

Cisco ASR 920 Series Aggregation Services Router

SNMP Dying Gasp Enhancement

This feature enables FPGA based effective space utilization between Ethernet OAM and SNMP. Use the platform-oam-snmp-dg-enable command on Cisco router to configure this feature.

IP SLAs

TWAMP Light

This feature enables you to configure a TWAMP Light session using the ip sla responder twamp-light test-session command.

MPLS Layer 2 VPNs

EVPN Integrated Routing and Bridging (L2 and L3 Anycast Gateway) and Data Center Interconnect or Border Leaf (Single Homing)

This feature allows the devices to forward both layer 2 or bridged and layer 3 or routed traffic providing optimum unicast and multicast forwarding for both intra-subnets and inter-subnets within and across data centers. Data Center Interconnects (DCI) products are targeted at the Edge or Border Leaf (BL) of data center environments, joining data centers to each other in a point-to-point or point-to-multipoint fashion, or at times extending the connectivity to internet gateways or peering points.

On-Change Notifications for L2VPN Pseudowire

This feature allows you to subscribe on-change Network Configuration Protocol (NETCONF) notifications for L2VPN pseudowire. You can generate an alert from a device when the pseudowire status changes.

QoS: Policing and Shaping

IP Address Range-Based Filtering Support for CoPP ACL

The CoPP ACL Template feature supports Ingress on In-band Management Loopback interface and Ingress on Data plane interface to block traffic using MPLS. CoPP ACL supports Source IP based filtering.

Segment Routing

SR-PM Delay Deduction (Loopback Mode)

This feature improves the SR-PM detection time as the PM probes are not punted on the remote nodes. Also, it does not a require a third-party support for interoperability.

SR-TE PM: Liveness of SR Policy Endpoint

• End-to-end liveness is verified before activating the candidate path in the forwarding table.

• End-to-end liveness failure can trigger re-optimization to another path by deactivating the current path.

Segment Routing Flexible Algorithm with OSPF

This feature allows you to configure Segment Routing Flexible Algorithm with OSPF. Flexible Algorithm with OSPF supports metric minimization and avoidance, multi-plane, delay metric with rounding, and ODN with auto-steering.

Segment Routing Policy Counters

This feature enables statistic counters to be displayed when traffic passes over the SR-TE tunnel.

You can use the command show segment-routing traffic-eng policy name policy name to view the counters.

Upgrading the Software on the Cisco ASR 920 Series Routers

Secondary ROMMON Version Auto Upgrade

After primary ROMMON version is auto upgraded, secondary ROMMON version auto upgrade process takes place. The secondary ROMMON upgrade is only completed during the next planned manual reload of the router.
