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 Cupertino 17.7.1a is the first release for Cisco 1000 Series Integrated Services Routers in the Cisco IOS XE Cupertino 17.7.x release series.



Note

Starting with Cisco IOS XE Amsterdam 17.3.2, 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).


New and Changed Hardware and Software Features

New and Changed Hardware Features

There are no new or enhanced features introduced in this release.

New and Changed Software Features

Table 1. New Software Features

Feature

Description

Marking Packets Sent Via ATM Interface With COS(BITP) Value

This feature introduces the set cos 3 command using which, you can configure the router to mark the packets with a cos (bitp) value. The marked packets are indicators of priority for the user and based on the priority level, bandwidth will be allocated.

Multicast - mcast group calculation

The show ip multicast overlay-mapping command displays an underlay group address from the overlay group address which is used to troubleshoot or configure the network. The output includes the underlay group address that is within the configured SSM (Source Specific Multicast) address range.

Flexible NetFlow Support on BD-VIF

This feature introduces Flexible NetFlow (FNF) support on Bridge Domain Virtual IP Interfaces (BD-VIF). Flexible Netflow provides improved optimization and performance, enhanced security, and increased flexibility and scalability to the network. You can configure FNF on a BD-VIF using the ip flow monitor command.

Storm Control Support for Cisco 1000 Integrated Services Routers

This feature prevents LAN ports from being disrupted by a unicast, broadcast, or multicast traffic storm on physical interfaces. It allows user to define the threshold rate of the traffic storm and choose the action that would be taken in storm.

YANG Configuration Models for CUBE

From Cisco IOS XE Cupertino 17.7.1a, YANG models are available to configure and manage CUBE as part of the Cisco SD-WAN solution.

YANG Model Version 1.1

Cisco IOS XE Cupertino 17.7.1a uses the YANG version 1.0; however, you can download the Cisco IOS XE YANG models in yang version 1.1 from GitHub at https://github.com/YangModels/yang/tree/master/vendor/cisco/xe folder. For inquiries related to the migrate_yang_version.py script or the Cisco IOS XE YANG version 1.1 migration process, send an email to xe-yang-migration@cisco.com.

ZTP Configuration through YANG

ZTP is enabled through YANG models when NETCONF is enabled.

Programmability Features

Converting IOS Commands to XML

This feature helps to automatically translate IOS commands into relevant NETCONF-XML or RESTCONF/JSON request messages.

Smart Licensing Using Policy Features

Ability to save authorization code request and return in a file and simpler upload in the CSSM Web UI

If your product instance is in an air-gapped network, you can now save an SLAC request in a file on the product instance. The SLAC request file must be uploaded to the CSSM Web UI. You can then download the file containing the SLAC code and install it on the product instance. You can also upload a return request file in a similar manner.

With this new method you do not have to gather and enter the required details on the CSSM Web UI to generate an SLAC. You also do not have to locate the product instance in the CSSM Web UI to return an authorization code.

In the CSSM Web UI, you must upload the SLAC request or return file in the same way as you upload a RUM report. In the required Smart Account, navigate to ReportsUsage Data Files.

See: No Connectivity to CSSM and No CSLU, Workflow for Topology: No Connectivity to CSSM and No CSLU, Saving a SLAC Request on the Product Instance, Removing and Returning an Authorization Code, Uploading Data or Requests to CSSM and Downloading a File.

Account information included in the ACK and show command outputs

A RUM acknowledgement (ACK) includes the Smart Account and Virtual Account that was reported to, in CSSM. You can then display account information using various show commands. The account information that is displayed is always as per the latest available ACK on the product instance. See: show license summary, show license status, show license tech.

CSLU support for Linux

CSLU can now be deployed on a machine (laptop or desktop) running Linux.

See: CSLU, Workflow for Topology: Connected to CSSM Through CSLU, Workflow for Topology: CSLU Disconnected from CSSM

Factory-installed trust code

For new hardware and software orders, a trust code is now installed at the time of manufacturing.

Note 

You cannot use a factory-installed trust code to communicate with CSSM.

See: Overview, Trust Code.

RUM Report optimization and availability of statistics

RUM report generation and related processes have been optimized. This includes a reduction in the time it takes to process RUM reports, better memory and disk space utilization, and visibility into the RUM reports on the product instance (how many there are, the processing state each one is in, if there are errors in any of them, and so on).

See: RUM Report and Report Acknowledgement, Upgrades, Downgrades, show license rum, show license all, show license tech.

Support for trust code in additional topologies

A trust code is automatically obtained in topologies where the product instance initiates the sending of data to Cisco Smart License Utility (CSLU)and in topologies where the product instance is in an air-gapped network.

See: Trust Code, Connected to CSSM Through CSLU, Tasks for Product Instance-Initiated Communication, CSLU Disconnected from CSSM, Tasks for Product Instance-Initiated Communication, No Connectivity to CSSM and No CSLU, Workflow for Topology: No Connectivity to CSSM and No CSLU

Support to collect software version in a RUM report

If version privacy is disabled (no license smart privacy version global configuration command), the Cisco IOS-XE software version running on the product instance and the Smart Agent version information is included in the RUM report.

See: license smart (global config)

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 recommended ROMmon version is 17.6(1r).

  • If the manufacturing date is less than 0x2535, you can upgrade to the recommended ROMmon version 17.5(1r) or later.

  • The minimal or recommended ROMmon version for devices using Cisco IOS XE 17.5 to 17.7 is 17.5(1r) or later.
