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).


System Requirements

The following are the minimum system requirements:


Note

There is no change in the system requirements from the earlier releases.


  • Memory: 4GB DDR3 up to 16GB

  • Hard Drive: 200GB or higher (Optional). (The hard drive is only required for running services such as Cisco ISR-WAAS.)

  • Flash Storage: 4GB to 32GB


    Note

    There is no change in the flash storage size from the earlier releases. The flash storage size must be equal to the system memory size.


  • NIMs and SM-Xs: Modules (Optional)

  • NIM SSD (Optional)

Upgrading Field-Programmable Hardware Devices

The hardware-programmable firmware is upgraded when Cisco 4000 Series ISR contains an incompatible version of the hardware-programmable firmware. To do this upgrade, a hardware-programmable firmware package is released to customers.

Generally, an upgrade is necessary only when a system message indicates one of the field-programmable devices on the Cisco 4000 Series ISR needs an upgrade, or a Cisco technical support representative suggests an upgrade.

From Cisco IOS XE Release 3.10S onwards, you must upgrade the CPLD firmware to support the incompatible versions of the firmware on the Cisco 4000 Series ISR. For upgrade procedures, see the Upgrading Field-Programmable Hardware Devices for Cisco 4000 Series ISRs.

Table 2. New Software Features in Cisco IOS XE 17.7.1a

Feature

Description

Cisco ThousandEyes Enterprise Application Hosting

The Cisco ThousandEyes Enterprise Agent Application introduces the functionality to inherit the Domain Name Server (DNS) information from the device. With this enhancement, the DNS field in vManage ThousandEyes feature template is an optional parameter.

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.

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.

Support for NGE Cipher Suites

This feature supports the Next Generation Encryption (NGE) cipher suites for secure voice signaling and secure media. These cipher suites are applicable for both STCAPP analog phone and SCCP DSPFarm conferencing service. These cipher suites provide confidentiality, integrity, and authenticity to validate messages.

TLS Support on IOS-XE Dataplane

You can now configure Cisco 4000 Series Integrated Services Router to accept remote user access to enterprise networks. This remote access is provided through a Secure Socket Layer (SSL)-enabled SSL VPN gateway that permits remote users to establish a secure VPN tunnel.

Cisco Unified Border Element (CUBE) Features

CUBE: Secure Web Socket-based Media Forking on Cisco 4431, 4451-X, and 4461 Integrated Services Routers

From Cisco IOS XE Cupertino 17.7.1a, CUBE can use WebSockets to handle media forking with Cloud Speech Services on the Cisco 4431, 4451-X, and 4461 Integrated Services Routers platforms, apart from the existing support on Cisco Catalyst 8000V Edge platform.

CUBE: YANG Configuration Models

From Cisco IOS XE Cupertino 17.7.1a, YANG models are available to configure and manage CUBE.

Programmability Features

Converting IOS Commands to XML

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

YANG Model Version 1.1

Cisco IOS XE Cupertino 17.7.1a uses the YANG version 1.0; however, you can download the 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 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.

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).

Configure the Router for Web User Interface

This section explains how to configure the router to access Web User Interface. Web User Interface require the following basic configuration to connect to the router and manage it.

  • An HTTP or HTTPs server must be enabled with local authentication.

  • A local user account with privilege level 15 and accompanying password must be configured.

  • Vty line with protocol ssh/telnet must be enabled with local authentication. This is needed for interactive commands.

  • For more information on how to configure the router for Web User Interface, see Cisco 4000 Series ISRs Software Configuration Guide, Cisco IOS XE 17.
