NBAR Support on the EVC Service Instance

To classify the data packets, enable NBAR FIA-trace data for NBAR on the EFP interface. Quality of service (QoS) takes action on the output interface based on the NBAR traffic classification result..

EVPN Over MPLS with Distributed Anycast Gateways

Distributed anycast gateway (DAG) is a default gateway addressing mechanism in a BGP EVPN fabric. This feature enables the use of same gateway IP and MAC address across all the devices in an EVPN over MPLS network. This ensures that every device functions as the default gateway for the workloads directly connected to it. Additionally, it also, facilitates flexible workload placement, host mobility, and optimal traffic forwarding across the BGP EVPN fabric.

Configure Performance Measurement

This feature enables hardware timestamping. The Performance Measurement (PM) for link delay uses the light version of Two-Way Active Measurement Protocol (TWAMP) over IP and UDP.

Link Aggregation Group compatibility with Service Group

QOS policy is now extended on L2VPN, L3VPN and service-group together on port-channel interface.

Show commands for troubleshooting

The following command are added for troubleshooting CPU and memory usage:

• show processes cpu

• show processes memory

• show avc sd-service info summary

• show avc sd-service info detailed | inc DCS

• show processes cpu

• show processes memory

• show version

Micro BFD Support with LACP

Micro-BFD, which is supported for the physical member-links within a port-channel is now configured to receive BFD events and to create BFD sessions per member-link. The member-links can now receive BFD events after you enable Micro-BFD for the port-channel member-links.

You can use the Web UI to configure Smart Licensing on Cisco ASR 1000 platforms. For more information, see Web UI Online Help.

Configuring the Same Global Address for Static NAT and PAT

You can now configure the same global address within static NAT and static PAT. This configuration is supported only on outside static NAT.

The BGP large communities support a routing policy to control the distribution of routing information. The BGP large communities attribute provides the capability of tagging routes and modifying BGP routing policy on the device. BGP large communities can be appended or removed selectively on the large community attribute as the route travels from device to device.

Static Network Address Translation (NAT) allows the user to configure one-to-one translations of the inside local addresses to the outside global addresses. A new keyword stateless is introduced for Cisco IOS XE static NAT configuration and it applies only to static NAT command. When the static mapping is set to stateless, no sessions will be created for that traffic flow.

Hunt Stop for Server Groups

Server groups allow you to create simpler configurations by specifying a list of destination SIP servers for a single dial peer. When a call matches a dial peer that is configured with a server group, the destination is selected from the list of candidates based on a configured policy. If it is not possible to complete that call, the next candidate is selected. Alternatively, you can also choose to stop hunting through the group if a specified response code is received. If the call cannot be placed to any of the servers in the group, or hunting is stopped, call processing continues to the next preferred dial-peer.

VoIP Trace Serviceability Framework

VoIP Trace is a Cisco Unified Border Element (CUBE) serviceability framework, which provides a binary trace facility for persistently monitoring and troubleshooting SIP call issues. The VoIP Trace framework records both successful and failed calls. All call trace data is stored in system memory. In addition, data for calls with IEC errors is written to the logging buffer.

Smart Licensing using Policy reports license usage periodically based on an account policy, rather than requesting licenses based on past usage as in previous releases. Evaluation mode and license reservation are not supported. Frequent license requests used to go out from a device to CSSM in earlier versions. In the changed scenario, minimum reporting license usage is 8 hours. Now all the devices within a network follow the uniform approach of reporting their license usage to Smart Agent. The Smart Agent in turn creates a Resource Utilization Monitoring (RUM) report and dispatches to CSSM based on the Smart Agent reporting policy.

When establishing a call, CUBE allocates several RTP ports that are based on the media that are negotiated for the session. Some ports remain assigned even after the call ends. In the current behavior, show voip rtp statscommand displays only the ports allocated from the global table, even if the ports are allocated from all the three tables (Global port, media IP address-based, and media VRF-based). Now this command is enhanced to display the ports allocated from all the three tables. The command also displays the hung ports and allows you to release those ports. Releasing the hung ports increases the efficiency of the routers as more ports are available to receive calls.
