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.

Table 2. Software Features

Feature

Description

Segment Routing over IPv6 Dataplane

Segment Routing (SR) can currently be applied on Multiprotocol Label Switching (MPLS) dataplane. From Cisco IOS XE 17.12.1a, SR is supported over the IPv6 dataplane for the following protocols:-

  • Interior Gateway Protocol (IS-IS only)-

  • Border Gateway Protocol (BGP)

In addition, the following functionalities are available for Segment Routing over IPv6 dataplane:

  • Segment Routing Traffic Engineering Policies

  • Static Routes

  • Performance Management

  • Operations, Administration and Maintenance (OAM)

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)

IPv6 Unicast Support with DLEP

The IPv6 Unicast Support feature introduces support for IPv6 dataplane to RAR Dynamic Link Exchange Protocol.

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.

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.
