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 17.15.1a is the first release for Cisco 1000 Series Integrated Services Routers in the Cisco IOS XE 17.15.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:

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 17.15.1a
|
Feature |
Description |
||
|---|---|---|---|
|
Enhanced NAT Management |
From Cisco IOS XE 17.15.1a, the Enhanced NAT Management feature enables network operators to safeguard system performance by limiting NAT translations based on CPU usage with the ip nat translation max-entries cpu command. This feature also enables streamlining NAT synchronization in redundant systems using the ip nat settings redundancy optimized-data-sync command. | ||
|
The File Transfer using HTTP or HTTPs feature allows you to copy files from a remote server to your local device, using the copy command. From Cisco IOS XE 17.15.1a, you must provide the absolute file path when you execute the copy command, to transfer the file. |
|||
|
From Cisco IOS XE 17.15.1a, network administrators can monitor SD-Routing device alarms on Cisco Catalyst SD-WAN Manager. This feature enables SD-Routing devices to record and store various alarms generated by control components and routers. For more information, see Cisco SD-Routing Command Reference Guide. |
|||
|
Network-Wide Path Insights on Software Defined (SD) - Routing Devices |
Network-Wide Path Insights (NWPI) is a tool that allows network administrators to monitor Cisco SD-Routing deployment, identify network and application issues, and optimize the network. |
||
|
Configure Multiple WAN Interfaces on Cisco SD-Routing Devices Using a Custom VRF |
You can now create a custom VRF that hosts one or more WAN interfaces. You can extend this functionality to create multiple custom VRFs with each VRF hosting multiple WAN interfaces. These WAN interfaces now function as transport interfaces to establish control connections to the Cisco Catalyst SD-WAN Manager. Having multiple WAN interfaces ensures that there is resiliency in control connections and routing of transport traffic. |
||
|
Enabling Flow Level Flexible NetFlow Support for SD-Routing Devices |
The Flow-level Flexible NetFlow (FNF) feature allows you to monitor the NetFlow traffic and view all the flow-level FNF data that is captured including application-level statistics. |
||
|
This feature explains how to seamlessly upgrade and onboard an existing Cisco Routing device into the Cisco SD-WAN infrastructure. |
|||
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. |
