Note


For more information on the features and specifications of Cisco ASR 1000 Series Routers, refer to the Cisco ASR 1000 Series Routers datasheet.

For information on the End-of-Life and End-of-Sale Announcements for Cisco ASR 1000 Series routers, refer to the ASR 1000 Series End-of-Life and End-of-Sale Notices.



Note


The Cisco IOS XE 17.3 release is the last release in which subpackage upgrade is supported for the following platforms:

  • ASR 1004

  • ASR 1002-X

  • ASR 1001-X

  • ASR 1001-HX

  • ASR 1002-HX

The subpackage upgrade for these platforms will not be supported from Cisco IOS XE 17.4 release. These hardware platforms continue to support software redundancy.



Note


Some YANG models are not fully compliant with all the IETF guidelines. The errors and warnings shown while executing pyang with -–lint flag is currently deemed to be non-critical as they do not impact the semantic of the models or prevent the models from being used as part of the toolchains. To determine the issues with the models, run the check-models.sh script with --lint flag enabled.

It is recommended to ignore LEAFREF_IDENTIFIER_NOT_FOUND and STRICT_XPATH_FUNCTIONS errors types when running pyang for validation as they are non-critical errors and do not impact the YANG model functionality



Note


When you upgrade from one IOS XE release to another, you may see %Invalid IPV6 address error in the console log file. To rectify this error, enter global configuration mode, and re-enter the missing IPv6 alias commands and save the configuration. The commands will be persistent on subsequent reloads.



Note


Starting with Cisco IOS XE 17.3.x, with the introduction of Smart Licensing Using Policy, even if you configure a hostname for a product instance or device, only the Unique Device Identifier (UDI) is displayed. This change in the display can be observed in all licensing utilities and user interfaces where the hostname was displayed in earlier releases. It does not affect any licensing functionality. There is no workaround for this limitation.

The licensing utilities and user interfaces that are affected by this limitation include only the following:

  • Cisco Smart Software Manager (CSSM),

  • Cisco Smart License Utility (CSLU), and

  • Smart Software Manager On-Prem (SSM On-Prem).


New and Enhanced Software Features for Cisco IOS XE Amsterdam 17.3


Note


The Cisco IOS XE Amsterdam 17.3.1a is the first release for Cisco ASR 1000 Series Aggregation Services Routers in the Cisco IOS XE Amsterdam 17.3.1 release series.


Table 1. New Software Features in Cisco ASR 1000 Series Release Cisco IOS XE 17.3.x

Feature

Description

Support for IP Multicast over UDL functionality for PIM

The unicast and multicast routing protocols forward data on interfaces from which they have received routing control information using a bidirectional link. However, some network links are unidirectional, where the physical send-only interface is on the upstream router and the physical receive-only interface is on the downstream router. To control routing information in these unidirectional environments, use the IP multicast over UDL functionality.

Support for openconfig-lldp 0.2.1

This release supports version openconfig-lldp 0.2.1 of LLDP protocol. No additional configuration is required.

Improved out for show ip nat pool command

The output of the show ip nat pool command is improved to display extra details.

Improved output for show diagnostic command

The output of the show diagnostic command now includes details of the serial number of the card in the slot.

Partial Configuration on CPE

This feature introduces limited support for following multicast modules in native operational YANG models:
  • PIM

  • MROUTE

  • MFIB

Show platform software cef ipv4 feature-all command

This command displays CEF information from the following commands without having to run each command individually :
  • show ip route <network> <network mask>

  • show ip cef <network> <network mask> internal

  • show adjacency <adj_id> internal

  • show platform software ip rp active cef prefix <network>/<mask_length> detail

  • show platform software adjacency rp active index <platform_adj_id>

  • show platform software ip fp active cef prefix <network>/<mask_length> detail

  • show platform software adjacency fp active index <platform_adj_id>

  • show platform hardware qfp active feature cef-mpls adjacency handle <cpp_handle_id>

BGP EVPN Route Reflector for Route Types L2 Tenant Routed Multicast (L2 TRM) relies on new route types in the EVPN overlay to achieve the IGMP/MLD proxy functionality using the BGP route reflector with the following route types:
  • Selective Multicast Ethernet Tag Route (+6)

  • EVPN Multicast Join Synch Route (+7)

  • Multicast Leave Synch Route (+8)

Policy-Based Routing support to categorise Office365 traffic for Direct Internet Access

To identify and differentiate Office 365 network traffic, Microsoft provides a web service to publish Office 365 endpoints and services. The Cisco Software-Defined AVC (SD-AVC) and Cisco Network-Based Application Recognition (NBAR) use this web service to improve first packet classification of Office 365 traffic to categorize it as as either “optimize or “non-optimize."

Show packet tracer command

The output of the show platform packet-trace command now includes additional trace information for packets either originated from IOSd or destined to IOSd or other BinOS processes.

New cipher suites for IP ssh Client and Server Algorithm:

To configure the HMAC algorithm of HMAC-SHA2-256-ETM@openssh.com or HMAC-SHA2-512-ETM@openssh.com as a cryptographic algorithm for IP SSH client. These cipher suites can be used with the ip ssh client algorithm mac and ip ssh server algorithm mac commands.

Advertisement of Loopback Prefix SIDs of a Border Router in Multiple ISIS Domains

A border router can advertise loopback interface prefixes and the associated prefix Segment Identifiers (SIDs) in multiple ISIS domains. With such an advertisement, the routers in each associated domain can communicate with the border router using the same prefixes and prefix SIDs.

BGP Best External Path with MPLS VPN Inter-AS Options B and C

In autonomous Systems, you can configure border routers in MPLS VPN Inter-AS Option B and Inter-AS Option C deployments to compute the best external paths to PE nodes. The primary border router advertises best external paths to internal BGP (iBGP) peers as back-up paths so that if a link in a best path fails, traffic flows along the best external path.

Enable debug information for Multicast: The following debug commands are introduced to enable the debugging information for Multicast via ConfD/NetConf:
  • debug platform condition feature multicast controlplane level

  • debug platform condition interface gigabitEthernet 0/0/1.2 ipv4 access-list mcast

  • debug platform condition feature multicast dataplane v4mcast submode

  • debug platform condition feature multicast dataplane v6mcast submode

Table 2. New and Enhanced Features for Cisco Unified Border Element (CUBE)

Feature

Description

Support for Cisco ASR-1006

The Cisco CUBE is supported on Cisco ASR 1006-X with RP3 and ESP 100.

Support for 100 VRFs

The current support limit is 54 VRF instances on a CUBE box. This requires customers to purchase additional hardware to meet requirements. For deployments such as HCS support greater number of tenants per box, the limit of VRF instances is improved to 100 VRFs. This feature is also introduced on CUBE enterprise.

Dial Peer Binding with Live Traffic

The Live Bind feature allows you to either change or add binding on a dial-peer that does not have any active calls, while other dial-peers with the same binding has active calls.

Media Proxy Multi-forking using SIPREC

The SIPREC-based CUBE Media Proxy solution supports forking to multiple recorders.

OPUS Codec Negotiation

Support is introduced for OPUS audio codec with CUBE.

TLS Server Name Indication (SNI) - RFC6066

Support is introduced for Server Name Indication (SNI). SNI is a TLS extension that allows a TLS client to indicate the name of the server that it is trying to connect during the initial TLS handshake process.

Consumption of INVITE with Replaces

Currently, CUBE has a known limitation in handling re-INVITE with replace headers. With this feature, this limitation is addressed with CUBE consuming the INVITE with Replaces header and bridging the call dialogs appropriately. This feature enhancement is essential for interoperability of CUBE with Microsoft Teams.

New and Enhanced Software Features for Cisco IOS XE Amsterdam 17.3.2

Table 3. New Software Features in Cisco ASR 1000 Series Release Cisco IOS XE 17.3.2

Feature

Description

Smart Licensing Using Policy

An enhanced version of Smart Licensing, with the overarching objective of providing a licensing solution that does not interrupt the operations of your network, rather, one that enables a compliance relationship to account for the hardware and software licenses you purchase and use.

With this licensing model, you do not have to complete any licensing-specific operations, such as registering or generating keys before you start using the software and the licenses that are tied to it. Only export-controlled and enforced licenses require Cisco authorization before use. License usage is recorded on your device with timestamps and the required workflows can be completed at a later date.

Multiple options are available for license usage reporting – this depends on the topology you implement. You can use the Cisco Smart Licensing Utility (CSLU) Windows application, or report usage information directly to CSSM. A provision for offline reporting for air-gapped networks, where you download usage information and upload to CSSM, is also available

For a more detailed overview on Cisco Licensing, go to https://cisco.com/go/licensingguide.

Cisco DNA Support for Smart Licensing Using Policy

Cisco DNA Center supports Smart Licensing Using Policy functionality starting with Cisco DNA Center Release 2.2.2. The corresponding minimum required Cisco IOS XE Release for this platform is 17.3.2.

Implement the “Connected to CSSM Through a Controller” topology to have Cisco DNA Center manage a product instance. When you do, the product instance records license usage, but it is the Cisco DNA Center that initiates communication with the product instance to retrieve and report usage to Cisco Smart Software Manager (CSSM) and returns the acknowledgement (RUM ACK).

In order to meet reporting requirements, Cisco DNA Center provides ad hoc or on-demand reporting, as well as scheduled reporting options. Cisco DNA Center also provides workflows for the installation and removal of the Smart Licensing Authorization Code (SLAC) for a product instance, if applicable.

Note

 
On the Cisco DNA Center GUI, you can generate a SLAC only for HSECK9 licenses, and only for certain product instances. See the configuration guide for details.

New and Enhanced Software Features for Cisco IOS XE Amsterdam 17.3.3

Table 4. New Software Features in Cisco ASR 1000 Series Release Cisco IOS XE Amsterdam 17.3.3

Feature

Description

Smart Software Manager On-Prem (SSM On-Prem) Support for Smart Licensing Using Policy

SSM On-Prem is an asset manager, which works in conjunction with CSSM. It enables you to administer products and licenses on your premises instead of having to directly connect to CSSM. Here, a product instance is connected to SSM On-Prem, and SSM On-Prem becomes the single point of interface with CSSM. The product instance can be configured to push the required information to SSM On-Prem. Alternatively, SSM On-Prem can be set-up to pull the required information from a product instance at a configurable frequency. After usage information is available in SSM On-Prem, you must synchronize the same with CSSM, to ensure that the product instance count, license count and license usage information is the same on both, CSSM and SSM On‐Prem. Offline and online options are available for synchronization between CSSM and SSM On‐Prem.

Minimum Required SSM On-Prem Version: Version 8, Release 202102

Minimum Required Cisco IOS XE Version: Cisco IOS XE Amsterdam 17.3.3
