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 Software Features in Cisco IOS XE Everest 16.6.2

There are no new software features in Cisco IOS XE Everest 16.6.2.

New Software Features in Cisco IOS XE Everest 16.6.1

BFS QAM Configuration

The BFS provides a mechanism for a standardized downloading of applications, games, images, and other data formats required by the applications. The BFS QAM enables the router to transfer the broadcast data from an EC to the target platform such as a set-top unit.

Expanded GQI Protocol Support

Cisco cBR-8 routers support the Generic QAM Interface (GQI) version 1, version 1 Extension, and version 2. The GQI v1 Extension provides a more neutral distribution path to non-cisco SRM products. This version supports type-2 commands, three announce messages, and offers a filtering mechanism to alleviate flooding the SRM with events. GQIv1 extension also supports more than 255 QAM carriers on each LED.

Remote PHY DOCSIS 3.1 OFDM Channel Configuration

Cisco cBR routers support DS OFDM channels in an R-PHY system. The OFDM-channel-support includes one OFDM channel for each Remote PHY device (RPD) with a channel bandwidth up to 192 MHz and the modulation up to 4096 QAM.

Capped License Enforcement

The capped license enforcement feature allows you to set a limit to the number of licenses for each licensed feature on Cisco cBR-8.

Dynamic Multicast Replication Session

When users enable IPTV service on the Cisco cBR routers, to enhance the performance, the Cisco cBR routers support caching of dynamic multicast sessions, provide faster multicast forwarding, and provides faster and efficient IP Communicator messages.

Remote PHY PowerKey VOD

The line cards in R-PHY mode on Cisco cBR-8 supports session-based PowerKey VOD. PowerKEY VOD allows the operator to provide secure, encrypted video streams to a particular subscriber over the RF plant.

DOCSIS 3.1 Upstream

This feature supports DOCSIS 3.1 upstream on Cisco cBR-8 router. It includes the support for OFDMA channel, OFDMA channel bonding, upstream profile selection, upstream path selection, and so on.

DOCSIS 3.1 Downstream Resiliency for OFDM Channel

This feature supports the DOCSIS 3.1 downstream resiliency for OFDM channel. When the cable modem reports RF channel failure, downstream resiliency will take corresponding actions.

D3.1: Multiple OFDM channels per port: 16 per LC

This allows the profile override to be specified for a particular downstream OFDM channel. Thus with 2 OFDM downstream channels on a single CM, each channel can have a unique profile override.

New Software Features in Cisco IOS XE Everest 16.6.2

There are no new software features in Cisco IOS XE Everest 16.6.2.

Modified Software Features in Cisco IOS XE Everest 16.6.1

Lawful Intercept

The maximum value of cTap2MediationTimeout is updated to 260640 minutes.

Cisco Remote PHY Out-of-Band

Cisco RPD 2.1 system supports OOB 55-2. The OOB 55-2 system has a scheduled TDMA upstream, which is intolerant to packet network latency.

Modified Software Features in Cisco IOS XE Everest 16.6.2

There are no modified software features in Cisco IOS XE Everest 16.6.2.
