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 Dublin 17.12.1a is the first release for Cisco 1000 Series Integrated Services Routers in the Cisco IOS XE Dublin 17.12.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:

|---|---|---|---|---|---|
|
The Managed Cellular Activation solution provides a programmable subscriber identity module (SIM), called an eSIM, a physical SIM card that you can configure with a cellular service plan of your choice. When ordering a pluggable interface module (PIM) to provide cellular connectivity for your router, choose a PIM model with a preinstalled eSIM. The Managed Cellular Activation solution comes with a “bootstrap” cellular plan to provide internet connectivity with a limited amount of data intended only for Day 0 onboarding of the device to your cellular plan. For information about configuring Cisco SD-WAN Manager with the details of your cellular plan in preparation for onboarding the device, see the Cisco Managed Cellular Activation Configuration Guide. Prepare the configuration in Cisco SD-WAN Manager before powering on and onboarding the device, to avoid running out of the limited data in the bootstrap cellular plan. Added Cisco Managed Cellular Activation (eSIM) support for the following Pluggable Interface Module (PIM) models:

New and Changed Software Features in Cisco IOS XE 17.12.1a
|
Feature |
Description |
||
|---|---|---|---|
|
This feature allows you to perform management operations for SD-Routing devices using Cisco Catalyst SD-WAN Manager. You can use a single network manage system (Cisco Catalyst SD-WAN Manager) to monitor all the SD-Routing devices and therefore help in simplifying solution deployments. |
|||
|
To clean the cellular modem completely, users can press the physical factory-reset button on the device, which enables the inbuilt lte cellular-profile-cleanup command to erase the configuration setup and profiles. This command is disabled by default, but can be enabled only when the factory-reset button is pressed. |
|||
|
This enhancement introduces support for Quantum-Safe Encryption using Post-Quantum Preshared Keys for the following platforms:
|
|||
|
This feature allows you to delete the entries from the logging buffer. You can configure the local syslog retention period after which the entries are purged from the device automatically. To enable this feature, use the logging purge-log buffer days command. |
|||
|
TrustSec and Software-Defined Access Scale Measurement |
With this feature, the scale numbers for TrustSec and Software-Defined Access (SDA) are measured for the following:
|
||
|
Cube Features |
|||
|
From Cisco IOS XE Dublin 17.12.1a onwards, VoIP Trace for SIP messages displays cause code in the cover buffer. |
|||
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. |
