About Cisco 1000 Series Integrated Services Routers
The Cisco 1000 Series Integrated Services Routers (also referred to as router in this document) are powerful fixed branch routers based on the Cisco IOS XE operating system. They are multi-core routers with separate core for data plane and control plane. There are two primary models with 8 LAN ports and 4 LAN ports. Features such as Smart Licensing, VDSL2 and ADSL2/2+, 802.11ac with Wave 2, 4G LTE-Advanced and 3G/4G LTE and LTEA Omnidirectional Dipole Antenna (LTE-ANTM-SMA-D) are supported on the router.
 Note |
Cisco IOS XE 17.16.1a is the first release for Cisco 1000 Series Integrated Services Routers in the Cisco IOS XE 17.16.x release series. |
Note |
Starting with Cisco IOS XE Amsterdam 17.3.2 release, 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:

Product Field Notice
Cisco publishes Field Notices to notify customers and partners about significant issues in Cisco products that typically require an upgrade, workaround or other user action. For more information, see https://www.cisco.com/c/en/us/support/web/field-notice-overview.html.
We recommend that you review the field notices to determine whether your software or hardware platforms are affected. You can access the field notices from https://www.cisco.com/c/en/us/support/web/tsd-products-field-notice-summary.html#%7Etab-product-categories.
New and Changed Hardware and Software Features
New and Changed Software Features in Cisco IOS XE 17.16.1a
|
Feature |
Description |
||
|---|---|---|---|
|
Asymmetric Carrier Delay allows you to configure separate delay times for link-up and link-down event notification on physical interfaces. From Cisco IOS XE 17.16.1a, asymmetric carrier delay is supported on Cisco 1000 Series Integrated Services Routers. |
|||
|
Cisco ThousandEyes is a network intelligence platform that enables you to monitor the network traffic paths across internal, external, and internet networks in real time, and helps to analyze the network performance. From Cisco IOS XE 17.16.1a, Cisco ThousandEyes application is supported on Cisco 1000 Series Integrated Services Routers. |
|||
|
From Cisco IOS XE 17.16.1a, you can configure source interfaces for High-Speed Logging (HSL) and SysLog for security logging in Cisco SD-WAN Manager. You can also enable HSL for your firewall messages, to allow a firewall to log records with minimum impact to packet processing. |
|||
|
Disablement of Weak SSH Algorithms |
From Cisco IOS XE 17.16.1a, the ssh-rsa algorithm is disabled by default on port 22 to improve security. |
||
|
From Cisco IOS XE 17.16.1a, the output for the show cellular 0/x/0 connection command includes the following parameters:
|
|||
|
From Cisco IOS XE 17.16.1a onwards, you can retrieve events sent to the IOS process in the binary trace using the show logging process IOS module nhrp command, without enabling DMVPN event tracing. |
|||
|
In Cisco IOS XE 17.16.1a, you can now monitor TCP and RTP traffic on DMVPN tunnels for IKEv2 traffic using Application Response Time (ART) monitor and Media monitor respectively. This functionality is only supported on DMVPN tunnels with IKEv2 encryption. |
|||
| If you have configured crypto VPN solutions such as DMVPN, FlexVPN or Layer 3 VPNs on SD-Routing devices, you can use Cisco Catalyst SD-WAN Manager to visualize the VPN solution deployed in the network and observe the functioning of the devices using various states, stats, charts, and events. Having high visibility into the network can help identify errors in real time therefore reducing the network down time. | |||
| When Cisco IOS-XE autonomous devices transition to Cisco SD-Routing mode, the Unified Threat Defense (UTD) Container Migration feature ensures that existing container functionalities are preserved. From Cisco IOS XE 17.16.1a you can detect, upgrade, and manage UTD Security Virtual Images through Cisco Catalyst SD-WAN Manager. For devices without pre-existing containers, you can also install and manage UTD images using policy groups. | |||
|
From Cisco IOS XE 17.16.1a, Cisco Catalyst SD-WAN Manager enables site-to-site speed tests to measure bandwidth between devices over DMVPN tunnels. These tests check upload speed from the source device to the destination, and measure download speed from destination to the source device. |
|||
|
From Cisco IOS XE 17.16.1a onwards, you can use HTTP-based authentication for EST Client Support, using the enrollment http username [http_username] password [http_password] command. |
|||
|
From Cisco IOS XE 17.16.1a release, the Dying Gasp feature enables you to configure the organization code field value in the OAMPDU frame. |
|||
|
From Cisco IOS XE 17.16.1a, slice-type and slice-differentiator options are introduced for cellular profiles in 5G standalone networks. |
|||
| Cisco Unified Border Element (CUBE) | |||
|
Secure Communications Interoperability Protocol (SCIP) support in CUBE |
From Cisco IOS XE 17.16.1a onwards, support for Secure Communication Interoperability Protocol (SCIP) voice and video codec is available, that ensures secure traffic sessions between the endpoints. Preview Feature Disclaimer The Secure Communications Interoperability Protocol (SCIP) feature in Cisco IOS XE 17.16.1a release is available in 'preview’ mode as it includes limited functionality or incomplete software dependencies. Cisco reserves the right to disable preview features at any time without notice. Cisco Technical Support provides reasonable effort support for features in preview mode. There is no Service Level Objective (SLO) in response times for features in preview mode; response times may be slow. |
||
Note |
From Cisco IOS XE Release 17.9.1a, guestshell is removed from the IOS XE software image. As a result, Zero Touch Provisioning (ZTP) python script is no longer supported on Cisco 1000 Series Integrated Services Routers. If you need to use guestshell, then download it from https://developer.cisco.com/docs/iox/#!iox-resource-downloads/downloads. For more information, see Guestshell installation procedure. |
