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 17.11.1a is the first release for Cisco 1000 Series Integrated Services Routers in the Cisco IOS XE Dublin 17.11.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

Table 1. New Software Features

Feature

Description

Deprecation of Weak Ciphers

The minimum Rivest, Shamir, and Adleman (RSA) key pair size must be 2048 bits. The compliance shield on the device must be disabled using the crypto engine compliance shield disable command to use the weak RSA key.

Enabling the RSRP and RSRQ Parameters for Link Recovery on LTE Modems

This feature enables the RSRP (Reference Signal Received Power) and RSRQ (Reference Signal Received Quality) parameters that detect any network issues or malfunctions as part of the link-recovery feature on LTE modems.

To enable these parameters, the user can configure the lte modem link-recovery rsrp onset-threshold command for RSRP and lte modem link-recovery rsrq onset-threshold command for RSRQ.

Flex Support on Layer 2 and Layer 3 Ports

This feature enables the flex Layer 2 and Layer 3 capability in the Layer 2 switch ports of the Cisco 1000 Series Integrated Services Routers (ISRs). This allows to add more Layer 3 WAN ports on the device by configuring the last two Layer 2 switch ports to Layer 3 WAN ports using the no switchport command.

For more information, see Cisco IOS Interface and Hardware Component Command Reference.

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.

Redirecting Deprecated LISP Commands to Revised Versions

The following LISP commands have been revised:

Cube Features

Unified SRST: Concurrent use of Webex Calling Survivability Gateway and Unified SRST

From Cisco IOS XE Dublin 17.11.1a onwards, concurrent use of Cisco Webex Calling Survivability Gateway and Unified SRST is supported on the same router.

Smart Licensing Using Policy Features

Snapshots for Product Activation Key (PAK) licenses

Starting with Cisco IOS XE Dublin 17.11.1a, the PAK-managing library is discontinued and the provision to take a snapshot is no longer available. Software images from Cisco IOS XE Dublin 17.11.1a onwards rely only on the snapshotted information about PAK licenses. For more information, see: Snapshots for PAK Licenses.

If you have a PAK license without a snapshot, and you want to upgrade to Cisco IOS XE Dublin 17.11.1a or a later release, you will have to upgrade twice. First upgrade to one of the releases where the system can take a snapshot of the PAK license and complete DLC, and then again upgrade to the required, later release.


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 17.11.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 17.11.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 17.11.x directly.
