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).


New and Changed Software Features

Table 1. Software Features

Feature

Description

Download AnyConnect Profiles with IPSec IKEv2 VPN

This feature allows you to configure Internet Protocol Security (IPSec)-Internet Key Exchange (IKEv2) VPN to download AnyConnect profiles over SSL, for IOS-XE headends.
MACsec Fallback Key Support This feature introduces a fallback mechanism to re-establish the MKA session when it fails because of primary Pre-Shared Key (PSK) mismatch. This fallback mechanism can be configured by using the mka pre-shared-key key-chain command.
Support for Thousand Eyes Application on Routing Platforms Cisco ThousandEyes application is a cloud-ready, enterprise network-monitoring tool that provides an end-to-end view across networks and services. This tool helps in analyzing the network performance and provides insights into the Internet and enterprise networks.

Aggregate Throughput Throttling

For throughput levels greater than 250 Mbps and Tier 2 and higher tiers, when you configure the bidirectional throughput value on the device, aggregate throughput throttling is effective. This means that traffic is throttled in an aggregate manner irrespective of the distribution of the traffic in the upstream and downstream direction.

The bidirectional throughput is represented in the license PID (For example, DNA-C-500M-E-3Y and DNA-C-T2-E-3Y). The aggregate throughput is double the bidirectional throughput.

For more information, see Licenses and Licensing Models.

Programmability Feature

YANG Model Version 1.1
