The following commands were introduced or modified:

  • cable downstream onid
  • cable video reserved-pid
  • cable video multicast
  • cable video ip udp
  • cable video ip multicast
  • show cable video session

For more information, see the RFGW-10 Video document at the following URL:

http://www.cisco.com/c/en/us/td/docs/cable/rf_gateway/feature/guide/rfgw_scg/rfgw10_video.html

Spectral Inversion

By default UPX will send the inverted spectral signal to the output. Some STBs/Modems cannot process the inverted signals. Signals are inverted when QCF module converts 6 bit 64QAM constellation and 8 bit 256QAM constellation to 10 bit symmetric and power normalized QAM constellation. Effective with Cisco IOS-XE Release 3.4.0SQ, the QAM Constellation Spectral Inversion feature provides support for non-inverted modulated signals, on the Cisco RFGW-10 DS-384 line card.

To configure channel spectrum inversion (set inverted signal output) of QAM constellation, use the cable downstream spectral-inversion command.

For more information, see the cable downstream spectral-inversion command at:

Important Notes

The Cisco RF Gateway 10 Supervisor Engine 7-E uplink ports are not recommended for data or management traffic.
The Supervisor 7-E card has four uplink ports on its front panel. Only the top two ports are active in redundancy mode. However, in redundancy mode, packet loss occurs in the traffic paths between the uplink ports on the standby Supervisor card and the switch fabric on the active Supervisor card. There is no packet loss for uplink ports on active supervisors.
The uplink ports on the Cisco RFGW-10 DS-384 and the Cisco RFGW-10 DS-48 line cards are recommended for data and management traffic.

Cisco IOS-XE Release 3.4.1SQ

  • Effective with Cisco IOS-XE Release 3.4.1SQ, the reserved PID range is 256 - 8159.
  • Effective with Cisco IOS-XE Release 3.4.1SQ, the show cable depi-ctrl-sessions teardown details command is introduced to view the session failure reason and the time of failure for particular DEPI session.
  • Effective with Cisco IOS-XE Release 3.4.1SQ, the cable downstream 8MHz-overlap-start-freq frequency command is introduced to configure the starting frequency for the 8MHz overlap block for Annex A.

Cisco IOS-XE Release 3.4.0SQ

  • Effective with Cisco IOS-XE Release 3.4.0SQ, the onid keyword is removed from the cable downstream tsid command and replaced with the cable downstream onid command.
  • Effective from Cisco IOS-XE Release 3.4.0SQ, if Annex A is configured, then the Logical QAM groups must be configured contiguously, for example, lqam-group1, lqam-group2, lqam-group3, and so on.
  • Effective with Cisco IOS-XE Release 3.4.0SQ, while using the replicate-qam command, the keywords qam , Qam , qam-red , Qam-red should be explicitly typed. Typing q or Q and pressing Tab will not auto-complete it.
  • Effective with Cisco IOS-XE Release 3.4.0SQ, a replicate with DEPI remote learn should be removed from the QRG before defaulting it, if not it may lead to QRG corruption.
  • Effective with Cisco IOS-XE Release 3.4.0SQ, a PID should be filtered before scrambling a session, filtering of PID on the scrambled session can lead to unwarranted results.
  • Effective with Cisco IOS-XE Release 3.4.0SQ, bulk QRG removal is supported only through GUI. It takes about 3 seconds to complete the action with this option. While using this option the user should not simultaneously access the console to enter any commands. If the console is accessed simultaneously, the QRG removal in the standby supervisor card may be affected.
  • Effective with Cisco IOS-XE Release 3.4.0SQ, scrambling of MPTS remap sessions are not supported.

Open Caveats for Cisco IOS-XE Release 3.4.1SQ

W
Description

CSCur19521

Symptom: In a very rare occurrence, continuous tracebacks occur. The standby Supervisor card is continuously reset. the following traceback is observed:

%COMMON_FIB-2-IF_NUMBER_ILLEGAL: STANDBY:Attempt to create CEF interface for Qam7/1.44 with illegal if_number: 0
 

Condition: This occurs when the max carriers are removed and set. The Supervisor card is configured with 1:1 line card redundancy and all channels in the line card are configured with Video and DEPI mode. Automated script configures supervisor max-carriers by setting & unsetting it continously using cable downstream max-carriers on range of QAM interfaces thru interface range qam .

This behavior was never observed with manual operation with the above command. One of 20 attempts can get this scenerio with automated script. Repeat these steps atleast 16-17 times.
