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:

  • Cisco Smart Software Manager (CSSM),

  • Cisco Smart License Utility (CSLU), and

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


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 17.12.2

This release provides a fix for CSCwh87343: Cisco IOS XE Software Web UI Privilege Escalation Vulnerability. For more information, see the Security Advisory: cisco-sa-iosxe-webui-privesc-j22SaA4z.

Table 1. New Software Features

Feature

Description

Cisco Managed Cellular Activation (eSIM)

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) model:

  • 5G Sub-6 GHz PIM, model P-5GS6-R16-GL

Note

 

In this context, eSIM refers to a removable SIM pre-installed by Cisco. In other contexts, eSIM can refer to a non-removable SIM embedded in a cellular-enabled device.

New and Changed Software Features in Cisco IOS XE 17.12.1a

Table 2. New Software Features

Feature

Description

Managing the SD-Routing Devices Using Cisco SD-WAN Manager

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.

Profile Clean-up on LTE Modems Using Factory Reset Button

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.

Quantum-Safe Encryption Using Post-Quantum Preshared Keys

This enhancement introduces support for Quantum-Safe Encryption using Post-Quantum Preshared Keys for the following platforms:

  • Cisco 1000 Series Integrated Services Routers

  • Cisco Catalyst 8500 Series Edge Platforms

Support for Automatic Log Deletion

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:

  • Security Group Tag (SGT) or Destination Group Tag (DGT) Policies

  • Unidirectional IPv4 SGT Exchange Protocol (SXP) connections

  • Bidirectional IPv4 SXP connections

  • IPv4 SGT Bindings

  • IPv6 SGT Bindings

  • Security Group Access Control Entries (SG ACEs)

Cube Features

CUBE/LGW: Cover Buffer Enhancements for VoIP Trace

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.


Cisco ISR1000 ROMmon Compatibility Matrix

The following table lists the ROMmon releases supported in Cisco IOS XE 16.x.x releases and Cisco IOS XE 17.x.x releases.


Note


To identify the manufacturing date, use the show license udi command. For example:

Router#show license udi 
UDI: PID:C1131-8PLTEPWB,SN:FGLxxxxLCQ6

The xxxx in the command output represents the manufacturing date.

  • If the manufacturing date is greater than or equal to 0x2535, the manufactured ROMmon version is 17.6(1r) or higher.

  • If the manufacturing date is less than 0x2535, the ROMmon will be automatically upgraded to 17.5(1r) or above when the Cisco IOS XE 17.9.x release is installed.

  • The minimal or recommended ROMmon version for devices using Cisco IOS XE 17.5 or later is 17.5(1r) or later.



Note


To upgrade to Cisco IOS XE Dublin 17.12.x, follow these steps:

  1. If you are on a device that is running software version between Cisco IOS XE 16.x to Cisco IOS XE 17.4.x, upgrade to any IOS XE image between Cisco IOS XE 17.5.x to Cisco IOS XE 17.10.x.

  2. After performing step a, upgrade to Cisco IOS XE 17.12.x.

  3. For devices that are running on software version Cisco IOS XE 17.5.x or later, you can upgrade to Cisco IOS XE 17.12.x directly.
