Feature

Description

Support for broadband features and functionalities with DNA Network Advantage Tier 3 license

From Cisco IOS XE 17.9.3a release, the following functionalities and features are supported on C8500-12X and C8500-12X4QC platforms with DNA Network Advantage Tier 3 license:

  • Layer 2 Tunnel Protocol Network Server (LNS)

  • Broadband Network Gateway (BNG)

  • Layer 2 Access Concentrator (LAC)

  • Intelligent Services Gateway (ISG)

  • Intelligent Wireless Access Gateway (iWAG)

  • PPP and IP sessions

New and Changed Software Features in Cisco IOS XE 17.9.2a

There are no new software features in this release.

New and Changed Software Features in Cisco IOS XE 17.9.1a

Table 2. Software Features

Feature

Description

Disabling USB Ports

You can now use the platform usb disable command to disable the USB ports on Cisco Catalyst 8500 Edge Series platforms.

Increase ACE Scale Limit Per OGACL

This feature provides an increase in the ACE (Access Control Engine) scale limit per ACL and OGACL(Object Group Access Control List) as the current implementation of CACE (Common Adaptive Classification Engine) has a total limit of only 64K entries. The scale for this feature is 1D and the scale information for OGACL is 3000 ACE entries per OGACL, 2400 OGs and 100 networks per OG.

Logging Destination IP Address and Port Details

The ip nat settings log-destination command is introduced in Carrier Grade Network Address Translation (CGN) mode to include the destination IP address and the destination port details in the add and delete HSL records.

IPsec Dual Stack Support on Non Cisco Devices

This feature provides the capabilities to carry both IPv4 and IPv6 traffic using a single IPsec Security Association (SA) that is tunnelled over IPv4. From IOS XE release 17.9.1a onwards, Cisco supports specific subnets in the access control list when the ingress end of the tunnel interface is configured with a third party IPsec client. With the introduction of the SVTI single security association dual stack feature, you can now manage the business-to-business services and other IOT business efficiently.

Support for Unicast-to-Multicast Destination Reflection

This feature introduces support for configuration of unicast-to-multicast destination reflection to facilitate unicast-to-multicast destination translation and unicast-to-multicast destination splitting. It also provides the capability for users to translate externally received unicast destination addresses to multicast addresses.

MACsec Extended Packet Numbering (XPN) Support

This enhancement introduces support for extending the packet number (PN) for MACsec frames from 32-bit to 64-bit. The 64-bit extended packet number (XPN) eliminates the need for frequent SAK(Security Association Key) rekey due to exhaustion of the 32-bit PN that may occur in high-capacity links.

Support for BGP additional paths with label-unicast unique mode

This enhancement introduces support for configuring BGP additional paths when label-unicast unique mode is configured.

Smart Licensing Using Policy Features

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.

Note: When using a VRF, the supported transport types are smartand cslu only.)

For more information, see license smart (global config)

Feature Navigator

You can use Cisco Feature Navigator (CFN) to find information about the features, platform, and software image support on Cisco Catalyst 8500 Series Edge Platforms. To access Cisco Feature Navigator, go to https://cfnng.cisco.com/ An account on cisco.com is not required.
