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) models:

5G Sub-6 GHz PIM, model P-5GS6-R16-GL
LTE CAT 18 PIM, model P-LTEAP18-GL
LTE CAT 6 PIM, models P-LTEA-EA, P-LTEA-LA
LTE CAT 7 PIM, models P-LTEA7-NA, P-LTEA7-EAL, P-LTEA7-JP

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 17.9.1a

Table 6. New Software Features

Feature

Description

New mechanism to send data privacy related information

A new mechanism to send data privacy related information was introduced. This information is no longer included in a RUM report.

If data privacy is disabled (no license smart privacy{all|hostname|version} command in global configuration mode), data privacy related information is sent in a separate sync message or offline file.

Depending on the topology you have implemented, the product instance initiates the sending of this information in a separate message, or CSLU and SSM On-Prem initiates the retrieval of this information from the product instance, or this information is saved in an offline file. For more information, see license smart (global config).

Hostname support

Support for sending hostname information was introduced. If you configure a hostname on the product instance and disable the corresponding privacy setting (no license smart privacy hostname command in global configuration mode), hostname information is sent from the product instance, in a separate sync message or offline file.

Depending on the topology you have implemented, the hostname information is received by CSSM, CSLU, and SSM On-Prem. It is then displayed on the corresponding user interface. For more information, see license smart (global config).

With the introduction of this enhancement, the hostname limitation which existed from Cisco IOS XE Amsterdam 17.3.2 to Cisco IOS XE Cupertino 17.8.x – is removed. In these earlier releases, hostname information is not sent or displayed on various licensing utilities (CSSM, CSLU, and SSM On-Prem).

RUM Report Throttling

For all topologies where the product instance initiates communication, the minimum reporting frequency is throttled to one day. This means the product instance does not send more than one RUM report a day.

The affected topologies are: Connected Directly to CSSM, Connected to CSSM Through CSLU (product instance-initiated communication), CSLU Disconnected from CSSM (product instance-initiated communication), and SSM On-Prem Deployment (product instance-initiated communication).

This resolves the problem of too many RUM reports being generated and sent for certain licenses. It also resolves the memory-related issues and system slow-down that was caused by an excessive generation of RUM reports.

You can override the reporting frequency throttling, by entering the license smart sync command in privileged EXEC mode. This triggers an on-demand synchronization with CSSM or CSLU, or SSM On-Prem, to send and receive any pending data.

RUM report throttling also applies to the Cisco IOS XE Amsterdam 17.3.6 and later releases of the 17.3.x train, and Cisco IOS XE Bengaluru 17.6.4 and later releases of the 17.6.x train. From Cisco IOS XE Cupertino 17.9.1, RUM report throttling is applicable to all subsequent releases.

Virtual Routing and Forwarding (VRF) Support

On a product instance where VRF is supported, you can configure the license smart vrf vrf_string command and use a VRF to send licensing data to CSSM, or CSLU, or SSM On-Prem. For more information, see license smart (global config)

Note

When using a VRF, the supported transport types are smart and cslu only.

New and Changed Software Features in Cisco IOS XE 17.8.1a

Table 7. New Software Features
Feature	Description
Booster Performance license	The Booster Performance license enables unthrottled throughput (for unencrypted traffic). Without it, throughput for unencrypted traffic is restricted to 500 Mbps. To enable the license, enter the platform hardware throughput level boost command in global configuration mode.
Support for X.25 protocol on Cisco 1100 Terminal Services Gateway	The X.25 protocol is now supported on Cisco 1100 Terminal Services Gateway. X.25 is the ITU-T standard that defines connections maintained between Data Terminal Equipment (DTE) and Data Circuit-terminating Equipment (DCE) for remote terminal access and computer communications.

New and Changed Software Features in Cisco IOS XE 17.6.6a

New and Changed Software Features in Cisco IOS XE 17.6.5a

New and Changed Software Features in Cisco IOS XE 17.4.1

Table 8. New Software Features

Feature

Description

Smart Software Manager On-Prem (SSM On-Prem) Support for Smart Licensing Using Policy:

SSM On-Prem is an asset manager, which works in conjunction with CSSM. It enables you to administer products and licenses on your premises instead of having to directly connect to CSSM.

Here, a product instance is connected to SSM On-Prem, and SSM On-Prem becomes the single point of interface with CSSM. The product instance can be configured to pushthe required information to SSM On-Prem. Alternatively, SSM On-Prem can be set-up to pull the required information from a product instance at a configurable frequency. After usage information is available in SSM On-Prem, you must synchronize the same with CSSM, to ensure that the product instance count, license count and license usage information is the same on both, CSSM and SSM On‐Prem. Offline and online options are available for synchronization between CSSM and SSM On‐Prem.

Minimum Required SSM On-Prem Version: Version 8, Release 202102
Minimum Required Cisco IOS XE Version: Cisco IOS XE Amsterdam 17.3.3. (If a product was first introduced in a later release, that release becomes the minimum required IOS-XE version for the product.)

Support for Synchronous Serial NIMs

From Cisco IOS XE Bengaluru 17.4.1, the following Synchronous Serial NIMs are supported on Cisco 1100 Series Terminal Services Gateway:

Cisco 1-Port Serial WAN Network Interface Card (NIM-1T)
Cisco 2-Port Serial WAN Network Interface Card (NIM-2T)
Cisco 4-Port Serial WAN Network Interface Card (NIM-4T)

Support for Cisco T1/E1 NIM

This feature extends support for the following Cisco T1/E1 NIM modules in data mode:

NIM-1MFT-T1/E1
NIM-2MFT-T1/E1
NIM-4MFT-T1/E1
NIM-8MFT-T1/E1
NIM-1CE1T1-PRI
NIM-2CE1T1-PRI
NIM-8CE1T1-PRI

The Cisco T1/E1 NIM module does not support TDM subdivision and analog services.

Support for Smart Licensing

Cisco DNA Center supports Smart Licensing Using Policy functionality starting with Cisco DNA Center Release 2.2.2. The corresponding minimum required Cisco IOS XE Release for this platform is Cisco IOS XE Bengaluru 17.4.1.

Implement the “Connected to CSSM Through a Controller” topology to have Cisco DNA Center manage a product instance. When you do, the product instance records license usage, but it is the Cisco DNA Center that initiates communication with the product instance to retrieve and report usage to Cisco Smart Software Manager (CSSM), and returns the acknowledgement (RUM ACK).

In order to meet reporting requirements, Cisco DNA Center provides ad hoc or on-demand reporting, as well as scheduled reporting options.

Note

Cisco DNA Center also provides workflows for the installation and removal of the Smart Licensing Authorization Code (SLAC) for a product instance, if applicable.

On the Cisco DNA Center GUI, you can generate a SLAC only for HSECK9 licenses, and only for certain product instances. See the configuration guide for details.
