Feature Support

Cisco IOS XE software is packaged in feature sets that consist of software images that support specific platforms. The feature sets available for a specific platform depend on which Cisco IOS XE software images are included in a release. Each feature set contains a specific set of Cisco IOS XE features.


Caution

Cisco IOS XE images with strong encryption (including, but not limited to 168-bit [3DES] data encryption feature sets) are subject to U.S. government export controls and have limited distribution. Strong encryption images to be installed outside the United States are likely to require an export license. Customer orders may be denied or subject to delay because of U.S. government regulations. When applicable, the purchaser or user must obtain local import and use authorizations for all encryption strengths. Please contact your sales representative or distributor for more information, or send an e-mail to export@cisco.com.

New and Changed Information

The following sections list the new hardware and software features supported on the Cisco cBR Series Converged Broadband Routers in this release:

New Hardware Features in Cisco IOS XE Everest 16.5.1

Cisco CCAP RF Line Card for Remote-PHY

The Cisco CCAP RF line card with no downstream and upstream PHY modules is connected with the Cisco 1.2GHz GS7000 SHO Node (Cisco GS7000 node). The PID of the line card is CBR-CCAP-LC-40G-R.

New Software Features in Cisco IOS XE Everest 16.5.1

MAC Filtering

This feature enables/disables MAC address filter on the backhaul interface. It supports 32 unicast filter entries per interface.

For more information, see the Cisco cBR Series Converged Broadband Routers Security and Cable Monitoring Configuration Guide.

DualCrypt Encryption Mode Support

This feature enables SRM to configure PowerKey and DVB CAS sessions on the same line card of the Cisco cBR-8 Converged Broadband Router.

For more information, see the Cisco cBR Converged Broadband Routers Video Features guide.

Fail-to-Clear

This feature enables the operator to control the configured DVB-encrypted sessions to function without encryption for a configured duration, when encryption for a session fails in Cisco cBR-8.

For more information, see the Cisco cBR Converged Broadband Routers Video Features guide.

OFDM Channel Power Profile

This feature helps in adjusting the power-level of 6 MHz bands in a DOCSIS 3.1 downstream OFDM channel.

For more information, see the Cisco cBR Converged Broadband Routers Layer 2 and DOCSIS 3.1 Configuration Guide.

Segment Routing

This feature allows you to enable segment routing mode on Cisco Converged Broadband Router, as an option for IPv6 address configurations under the sub mode.

For more information, see the Cisco cBR Series Converged Broadband Routers Layer 3 Configuration Guide for Cisco IOS XE Everest 16.5.1 guide.
