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)

Software Features

Table 1. New Software Features in Release Cisco IOS XE Bengaluru 17.6.1a

Feature

Description

Asymmetric Lease for DHCPv6 Relay Prefix Delegation This feature allows you to manage or change the lease renewal. It provides options to force renewal of lease and also detects when the lease is nearing the expiry date.
CUBE: OPUS Codec Transcoding From Cisco IOS XE 17.6.1 onwards, CUBE can transcode Opus encoded media streams. Because Opus codecs perform very well over the Internet, this feature is particularly beneficial when routing calls between the PSTN and Cloud calling services.
Cisco ThousandEyes Eterprise Application Hosting 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.
ISR Serviceability: Consistent System-report This feature lets you configure system reports that can provide critical information on issues that cause software crashes.
L2VPN Traffic SteeringUsing SR-TE Preferred Path This feature allows you to configure an SR policy as the preferred path for a VPWS or VPLS pseudowire. VPWS or VPLS pseudowires between same PEs can be routed over different SR policies based on the requirements.
PPPoE Client over VLAN Interface The PPPoE Client over VLAN interface enhancement allows you to configure the PPPoE client to establish a PPPoE session over a VLAN interface.
Unified CME: Availability with Catalyst Edge 8300 Platforms From Cisco IOS XE 17.6.1 onwards, CME is supported on Cisco 8300 Catalyst Edge Series platforms.
Voice: Class of Restriction YANG Configuration Model

YANG models were developed for the following CLIs as part of the Class of Restriction configuration:

  • dial-peer voice <tag> pots/voip corlist

  • dial-peer voice vad

  • dial-peer cor custom name <string>

  • dial-peer cor list <string> member <string>

  • voice num-exp <string1> <string2>

  • voice register pool <string> [no] cor {incoming | outgoing} cor-list-name {cor-list-number starting-number [- ending-number] | default}

Zone-Based Firewall Reclassification The Zone-Based Firewall (ZBFW) Reclassification feature is an enhancement to the Zone-Based Firewall feature. With this enhancement, any changes you make to the policy configuration on an existing firewall session is immediately enforced.

Note

From Cisco IOS XE Bengaluru 17.6.x, configuring a weak crypto algorithm generates a warning message. However, you can ignore this warning because the working of crypto algorithms is not impacted. For more information on weak crypto algorithms, see Supported Standards.
