New Software Features in Cisco IOS-XE Release 3.3.0SQ

This section describes the new software features supported in the Cisco IOS-XE Release 3.3.0SQ.

Video On Demand

RFGW10 allows users to select and watch video content on demand. Video on Demand (VoD) sessions are of unicast CBR SPTSs. Usually, the User-defined Mapping(table based mapping) or Session-based Signaling is used for VoD setup. VoD supports Trick Mode, which provides functionalities like fast forward, rewind, and pause for an MPEG bit stream.

For more information, see the Cisco RF Gateway 10 Software Configuration Guide at the URL:

http://www.cisco.com/en/US/docs/cable/rf_gateway/feature/guide/rfgw10_video.html

Switched Digital Video

Starting with Cisco IOS-XE Release 3.3.0SQ, RFGW10 supports Switched Digital Video (SDV) thereby effectively using the bandwidth. SDV sessions are typically Multicast SPTSs. The Session-based Signaling is required for the SDV sessions.

For more information, see the Cisco RF Gateway 10 Software Configuration Guide at the URL:

http://www.cisco.com/en/US/docs/cable/rf_gateway/feature/guide/rfgw10_video.html

Table based Video Session Mapping

Video session mapping is the mapping between the input sessions and the output sessions of the Cisco RFGW-10 UEQAM. An input session is identified by a destination IP address and an UDP port for the unicast session, and by a group and source IP address pair for a multicast session. An output session is identified by a QAM ID and a program number. The user-defined mapping is typically used in VoD or Digital Video Broadcast applications. You can specify the mapping using the CLI. This mapping can be used for both unicast and multicast sessions.

For more information, see the Cisco RF Gateway 10 Software Configuration Guide at the URL:

http://www.cisco.com/en/US/docs/cable/rf_gateway/feature/guide/rfgw10_video.html

Generic QAM Interface (GQI) Protocol

Effective with Cisco IOS-XE Release 3.3.0SQ, RFGW10 supports GQI Protocol version 2 (GQIv2). GQI is a protocol between RFGW and DNCS/USRM to setup video sessions dynamically.

For more information, see the Cisco RF Gateway 10 Software Configuration Guide at the URL:

http://www.cisco.com/en/US/docs/cable/rf_gateway/feature/guide/rfgw10_video.html

Edge Resource Management Interface (ERMI) Protocol

RFGW10 supports Cablelabs ERMI specification (CM-SP-ERMI-I03-081107). It supports Edge Resource Management Protocol (ERRP) & Real Time Streaming Protocol (RTSP).

For more information, see the Cisco RF Gateway 10 Software Configuration Guide at the URL:

http://www.cisco.com/en/US/docs/cable/rf_gateway/feature/guide/rfgw10_video.html

Cisco RF Gateway 10 GUI

Cisco RF Gateway 10 GUI is a web-based interface for configuring and managing the Cisco RFGW-10 Universal Edge Quadrature Amplitude Modulation (UEQAM) device. It is an embedded web application residing in the Cisco RFGW-10 UEQAM chassis. The GUI image (RFGW_GUI.tar) is embedded in the Cisco RFGW-10 IOS-XE image and is installed as part of the IOS-XE image installation. There are no configuration steps for installing this application.

For more information on this feature, see the Cisco RF Gateway 10 GUI document available at this URL:

http://www.cisco.com/en/US/docs/cable/rf_gateway/feature/guide/rfgw10_gui.html

Encryption of Video Sessions

Video sessions can be encrypted with the PowerKEY function.

PowerKEY is a conditional access system (CAS) that provides a range of services for protection of digital entertainment content, such as linear or broadcast service encryption, session-based encryption for video-on-demand or other on-demand services, and a pay-per-view purchase model including reservation mode and impulse mode.

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

http://www.cisco.com/en/US/docs/cable/rf_gateway/feature/guide/rfgw10_video.html

Fan Tray Failure Handling Enhancement

The failure of fan controllers is handled by the software in the following condition-action sets:

  • If less than 3 fans or fan controller fail, the failure is set as partial failure.
  • If more than 2 fans fail, the failure is set as critical error.

For partial failure, an error message is logged in syslog and the show environment and show facility-alarm status commands display the error messages. Errors are logged once in syslog; they are not displayed continuously.

For critical error, an error message is logged in syslog and the Supervisor card starts the four-minute shutdown timer. The Supervisor card shuts down all line cards and the second Supervisor card at the four-minute timeout. The active Supervisor card continues to be operational.


Caution To avoid hardware damage, power down the chassis immediately after the four-minute shutdown.

Load Balancing with QAM Partition

Effective with Cisco IOS-XE Release 3.3.0SQ, the term Load Balance Group (LBG) is used to identify QAM traffic that uses the mid-plane 10GE ports to forward traffic to the QAM carriers. LBGs must be used to reserve the bandwidth and set up video routes.

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

http://www.cisco.com/en/US/docs/cable/rf_gateway/feature/guide/rfgw10_video.html

RF Spanning (QAM Replication)

The QAM Replication feature allows users to replicate a single QAM output from one port to another port on the same Cisco DS-384 line card from the Supervisor card. The replicated QAM output uses the downstream Switch Port Analyzer (SPAN) licensing policy that allows additional downstream outputs using RF Spanning. The RF spanning feature allows replication of existing downstream output to other ports on the same line card. A QAM Replication Group (QRG) contains information about a single source QAM and its corresponding replicated copy or copies. A QRG contains only one pilot and a minimum of one and maximum of seven replicate QAMs. Each group is numbered with an identifier and contains the slot, port and channel number for both the source QAM ( pilot-qam ) and the destination QAM or QAMs ( replicate-qam ).

The following commands were introduced or modified:

  • cable qam-replication group
  • pilot-qam
  • replicate-qam
  • show cable qam-replication-group

For more information on this feature, see the Configuring the Cisco RFGW-10 DS-384 Line Card document available at this URL:

http://www.cisco.com/en/US/docs/cable/rf_gateway/linecard/ds384/configuration/guide/b_ds384_scg.html

Software Licensing

Effective with Cisco IOS-XE Release 3.3.0SQ, the Cisco RF Gateway 10 supports the PowerKEY and RF SPAN licenses.

The PowerKEY license enables the you to delay investing in QAM encryption until the entire network is ready for deployment. The RF SPAN license is used for replicate QAM channels.

For more information, see the Software License Activation for Cisco RF Gateway 10 Line Cards document at this URL:

www.cisco.com/en/US/docs/cable/rf_gateway/license/rfgw_license.html

QAM Partitioning - Video

With the introduction of the Cisco RFGW-10 DS-384 line card (with 384 QAM channels), the capacity of a fully-loaded Cisco RF Gateway 10 (with 10 line cards) is now 3840 QAM channels and 160 Gbps throughput. To cater to the increased capacity, and to use the resources of the Cisco RF Gateway 10 optimally, the Cisco IOS-XE Release 3.3.0SQ introduces a new tool—QAM Partition (QP).

QAM partitioning allows servers running different control plane protocols like Edge Resource Management Interface (ERMI) or Generic QAM Interface (GQI) to share the resources of the Cisco RF Gateway 10.

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

http://www.cisco.com/en/US/docs/cable/rf_gateway/feature/guide/rfgw10_video.html

CISCO-ENTITY-REDUNDANCY-MIB

Effective with Cisco IOS-XE Release 3.3.1SQ, the Cisco RFGW-10 supports the CISCO-ENTITY-REDUNDANCY-MIB. The Cisco RFGW-10 supports this MIB for Cisco DS-384 and Cisco DS-48 line card redundancy.

New and Changed MIB Information in Cisco IOS-XE Release 3.3.0SQ

The following MIB was updated in Cisco IOS-XE Release 3.3.0SQ:

SCTE-HMS-MPEG-MIB

Effective with Cisco IOS-XE Release 3.3.0SQ, the SCTE-HMS-MPEG-MIB is used to query Video session information on the Cisco RFGW-10. Querying these tables displays Input & output video session information on the QAM interfaces and channels for the Cisco RFGW-10 DS-384 line card.

Important Notes

Cisco IOS-XE Release 3.3.0SQ

The Cisco RF Gateway 10 Supervisor Engine 7-E uplink ports are not recommended for data or management traffic in Supervisor Redundancy Mode.

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 DS-384 Line Card with P4080 CPU Revision 3

Effective with Cisco IOS-XE Release 3.3.1SQ, the Cisco RFGW-10 supports the new version of the Cisco DS-384 line card with P4080 CPU revision 3. The Version Identifier (VID) of the revised Cisco DS-384 line card is 2. Ensure that you run Cisco IOS-XE Release 3.3.1SQ or later releases on the Supervisor engine 7-E for using the Cisco DS-384 VID 2 line card (with P4080 CPU revision 3).


NoteIf the Supervisor engine 7-E is running a release earlier than Cisco IOS-XE Release 3.3.1SQ, the Cisco RFGW-10 DS-384 VID 2 line card (with P4080 CPU revision 3) does not downgrade and hence, does not work.


For more information on the Cisco DS-384 line card, see Cisco RF Gateway 10 DS-384 Line Card Hardware Installation Guide at this URL:

Cisco RF Gateway 10 Remote Provisioning Utility (RPU-10)

The Cisco IOS-XE Release 3.3.0SQ supports the Cisco RF Gateway 10 Remote Provisioning Utility (RPU-10). Cisco RPU-10 is a Windows-based tool to simplify the initial provisioning of multiple RF Gateway 10 units in an operator's system. The PID for ordering the Cisco RPU-10 application is RFGW-10-RPU. The Cisco RF Gateway 10 uses the Cisco RPU-10 version 1.0 for this release.

Resolved Caveats for Cisco IOS-XE Release 3.3.1SQ

Caveat
Description

CSCuh36482

Symptom: A few existing session IDs may be missing for the following SNMP MPEG output tables:

mpegOutputProgTable

mpegOutputEsTable

Conditions: This occurs while running SNMP walk on the afore-mentioned MIB tables more than once.

Workaround: Use the following Cisco RFGW-10 show commands:

show cable video session all

show cable video session Output Statistics

CSCuh51230

Symptom: The SNMP query on mpegOutputTSNumPrograms MIB object does not show the correct count of all programs.

Condition: This occurs for MPTS streams.

Workaround: Use the show cable video session command for the particular MPTS session to know about the number of programs carried in MPTS stream.

CSCuh51954

Symptom: The standby Supervisor card resets continuously after a line-by-line synchronization error is displayed by the active Supervisor card.

Conditions: RFGW is configured with RF Spanning with Pilot and Replicate Channels. In this event, configuring ASI interface to monitor replicate QAM interface will trigger the error.

Workaround: There is no service impact. Use ASI interface for monitoring the non replicate QAM interfaces (pilot channels). Use the ASI interface during maintenance windows.

CSCuh57628

Symptom: While changing cable mode from clear to encrypt for all the carriers in the QAM (bulk change), multiple warning messages are displayed instead of showing single warning message.

Conditions: This issue occurs when you access the QAM page through GUI.

Workaround : There is no workaround.

CSCuh70103

Symptom: If a PowerKEY encrypted session fails due to "blob failure", some of the commands do not display the failed state of the session. Specifically, the show cable video session and show cable video session remote gqi command do not display any problem with the failed session. The show cable video gqi sessions does display the Current State as "Fail to Black".

Conditions: This occurs in the case of an encryption "blob failure" which should be extremely rare in the field. The blob failure indicates that Cisco RFGW-10 can not decode the encryption information sent in the session create from the DNCS. This implies that there must have been a problem in the encrypted key exchange or handling in the DNCS or Cisco RFGW-10.

Workaround: Use the show cable video gqi sessions command for encrypted sessions to ensure that they are encrypted.

CSCuh79811

Symptom: On a rare occasion, the standby Supervisor card resets after the redundancy reload shelf command is executed.

Conditions: This occurs when the following specific series of steps performed on Supervisor card:

1. Configure remote unicast sessions with Annex A.

2. Perform supervisor switch-overs.

3. When the redundancy reload shelf command is used at this juncture, the active Supervisor card switches over as standby.

Workaround: There is no service or functional impact. Reload the standby Supervisor card.

CSCuh86237

Symptom: Adding the line card to the line card redundancy group after inserting packets results in line card state progression failure and the secondary line card resets with following errors:

%LCRED-3-LC_STATE_PROG_FAILED: Redundant Line Card 11 (idx
Router#=11) state progression failure. Line card will be reset due to Platform Failure to download config to Linecard. (State: Active,Event: Cfg Dnld)
Defaulting the Qam interface having packets inserted results in errmsg
%RFGW-3-LINECARD_ERRMSG_ERR: SLOT 9:LC_ERRMSG_VIDEO_CAROUSEL_NOT_IN_QAM CHANGE_CRSL: CRSL 1, QAM 9
Inserting more than 1024 packets resutls in tracebacks
vscm_pi_session_incr_session_count -> total PI mpeg counts on slot 4 = 1029
 

Conditions: This occurs when inserting 48 packets ids and then adding the line card to an existing 1:N line card redundancy group. If the QAM channel is in shut state, with no frequency assigned , the show cable video packet all command output shows the Packet in ON State. Defaulting the QAM channel with packets inserted, results in the error messages. Inserting more than 1024 packets results in tracebacks.

Workaround: Configure line card redundancy group before inserting packets. Do not default the interface having packets inserted in them.

CSCuh95202

Symptom: Image verification fails for Cisco RFGW-10 IOS-XE images with the following message:

Digital signature verification failure
 

Conditions: This is observed when verify command is used on Cisco IOS-XE Release 3.2SQ images.

Caveat
Description

CSCuc56954

Symptom: On rare occasions, the following traceback and failure message observed on the Supervisor console:

"vscm_pi_stream_unique_id -> Unable to construct a unique id 203489281. Stream 1 on slot 3 carrier id 33 already exist"

Conditions: This occurs when the Supervisor card is configured for video remote mode on a few QAM channels and DNCS/USRM (Session Resource Manager) creates packet insertion sessions using GQI protocol. In this event, triggering the Supervisor card switchover will result in these tracebacks.

Workaround: This symptom will not exibit service or functional impact. Therefore, no workaround is required.

CSCue46589

Symptom: The UPX NACK message is displayed after 124 replicant groups configured on a port.

%RFGW-3-LINECARD_ERRMSG_ERR: SLOT 3:BB_ERRMSG_DS_PHY_UPX_ERR:wr cmd NACK for seq_num=0xa92,addr=0x212003e0,cmddata=0xc803f07f.b7500139.000005e8.00000650 556e6d61.74636820.62657477.65656e20 34204455.43204368.69707300.00000000 00000000.00000000.00000000.00000000, 00000000.00000feb.00000000.00000000 00000000.00000000.00000000.00000000 00000000.00000000.00000000.00000000 00000000.00000000.00000000.00000000, err_code=34
 

Conditions: This issue occurs when RFGW is configured with RF Spanning. Port1 & port2 are configured for pilot channels with more than 124 replicant groups combined. Port3 is configured with these replicant groups from both the ports that is , port3 channels are replicates from port1 & port2 respectively in a way that port3 channels form more than 32 routing groups (each routing group supports 4 channels). Each replicant has less than 4 channels in port3 which allows more than 32 routing groups.

Workaround: Do not attempt to configure a port with replicates with more than 32 routing LQAM groups. This is not recommended or supported.

CSCue55630

Symptom: On rare occasions, the following error messages occur:

%RFGW-3-IPC_SEND_MESSAGE: IPC send message 1 to port RFGW: lc 5:image upgrade on linecard 5 failed for reason timeout
%RFGW-3-UNEXPECTED: Linecard in slot 5 could not be upgraded to MV_APP_00000011_20130212-00012920
 

Conditions: This occurs when a Supervisor card is rebooted with an updated image.

Workaround: To recover, wait until IPC communications resume with the linecard and then reset the linecard using the hw-module slot reset command. Alternatively, a manual image upgrade with the cable image-upgrade download background forced command (while in "service internal") could prevent the errors.

CSCuf16894

Symptom: On a very rare occasion, the following line card error occurs during line card switch-over.

%RFGW-3-LINECARD_ERRMSG - LC_ERRMSG_VIDEO_UNKNOWN_PROG_NUM Snoop
 

Conditions: This occurs when the Supervisor card is configured with more than 20000 video sessions created by both table based sessions and GQI/ERMI protocols and slot12 of the Cisco RFGW-10 DS-384 line card is backing up those sessions in 1:N redundancy mode. In this event, performing line card switchover triggers these errors .

Workaround: There is no service or functional impact and may be ignored.

CSCug48487

Symptom: The following UPX errors and traffic flow is affected on replicated channels on the Cisco RFGW-10:

%RFGW-3-LINECARD_ERRMSG_ERR: SLOT 3:BB_ERRMSG_DS_PHY_UPX_ERR:wr cmd NACK for seq_num=0x4a0,addr=0x21000010,cmddata=0xa007fc56.847001bd.0000053a.000004e7 556e6d61.74636820.62657477.65656e20 34204455.43204368.69707300.00000000 00000000.00000000.00000000.00000000, 00000000.00000feb.00000000.00000000 00000000.00000000.00000000.00000000 00000000.00000000.00000000.00000000 00000000.00000000.00000000.00000000, err_code=2
 

Conditions: This issue occurs on Cisco RFGW10 chassis configured with DEPI remote learn QAM channels and they are replicated on other QAM channel using RF Spanning mechanism.

Workaround: Before attempting to change CMTS configuration, remove the particular pilot channel from the replication group and reconfigure the pilot channel after the changes are made in CMTS.

CSCug70582

Symptom: In a very rare occurence, 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.

1. Config 192 powerkey encrypted channels, 143 remote depi channels in LC7 and config 1:1 LCRED (LC 7, LC12)

2. Remove max-carriers using the cmd interface range qam & no cable downstream max-carriers .

3. Set the Max-carriers using the command cable downstream max-carriers .

4. Tracebacks are thrown.

Workaround: Active Supervisor card gets into inconsistent mode with standby Supervisor card and it can be recovered by resetting the chassis. Configure cable downstream max-carriers command in maintenance window.

CSCug73308

Symptom: Used bandwitdh for packet insertion may not be displayed incorrectly in the output of show controllers qam downstream command.

Conditions: This occurs when the PI sessions are cleared using the clear cable video session all command or any modification are made to the packet inserted QAM channel configuration.

Workaround: There is no service impact and therefore, requires no workaround.

CSCuh00372

Symptom: The following error occurs on a new active Supervisor card:

“%RFGW-3-LINECARD_ERRMSG_ERR: SLOT 11:LC_ERRMSG_VIDEO_CAROUSEL_NOT_USED DELETE_CRSL: 62s".
 

Condition: This occurs when a Supervisor card is switched over using the hw-module module reset command.

Workaround: There is no service impact. Only errors are displayed.

CSCuh01054

Symptom: The following error is displayed on the Supervisor console "*May 19 13:14:27.307 IST: %RFGW-3-IPC_SEND_MESSAGE: IPC send message 2 to port RFGW: lc 14:tcc dti on linecard 14 failed for reason internal error".

Conditions: This occurs when the active Timing, Control and Communication (TCC) card is reset.

Workaround: There is no service impact. Do not attempt to reset an active TCC card.

CSCuh22323

Symptom: In a rare occurence, the following message is observed on the Supervisor console:

%RFGW-3-UNEXPECTED: Unable to switchover to TCC on slot 14
 

Conditions: This occurs during bootup after the chassis is power-cycled.

Workaround: This symptom does not exhibit any service or functional impact and may be ignored.

CSCuh36482

Symptom: A few existing session IDs may be missing for the following SNMP MPEG output tables:

mpegOutputProgTable

mpegOutputEsTable

Conditions: This occurs while running SNMP walk on the afore-mentioned MIB tables more than once.

Workaround: Use the following RFGW-10 show commands:

show cable video session all

show cable video session Output Statistics

CSCuh37962

Symptom: In some instances, the following interactive warning message will be seen:

"WARNING:: Associated sessions and RF Profile of this QAM will be deleted. Proceed y/n ?[confirm]"
 

When configuring manually the user can answer y and proceed with no problems. However, the need for an interactive y/n answer can prevent automated provisioning tools from being able to load configurations.

Conditions: This occurs after defaulting all QAMs on a QAM port. Supervisor is configured with 1:1 LC redundancy mode with following sequence of steps executed on RFGW.

1. Configure few encrypted channels

2. Please perform 1:1 LCRED ( LC 7, 12)

3. Please reload Supervisor

4. Remove LCRED configuration

5. Remove max-carriers and assign new max-carrier

6. Try again to configure encrypted channels to hit this warning

Workaround: Manually configure the affected QAMs and answer “yes” when prompted. To use an automated provisioning tool, reload the RFGW10 shelf to clear the remaining sessions.

CSCuh38422

Symptom: In a very rare occurence, reconfiguration of the replicate channels in replcation group fails after the pilot channel is set to default.

Conditions: RFGW10 chassis configured with DEPI remote learn QAM channels and they are replicated to other QAM channel using RF Spanning mechanism. Set the remote learn mode as the default pilot channel set and try to add the pilot channel with remote learn mode configured in the same replication group

Workaround: Do not attempt to default the pilot channel while the remote learn mode is set. Remove the the pilot channel from replication group before attempting to default the pilot channel.

CSCuh48438

Symptom: The DS384 line card fails to boot. The following UPX error messages is displayed:

%RFGW-0-LINECARD_ERRMSG_EMERG: SLOT 3:LC_ERRMSG_FAILOVER_TRIGGER UPX Hi priority event (SET): module:1 idx:773 desc:UPX RF Power Level out of spec, type 11, data 0x8001b305
 
%RFGW-3-LINECARD_FAILURE: Linecard in slot 3 is reporting a Fpga Failure (0x0001)
 
%C4K_CHASSIS-2-LINECARDDS384MAJOREVENT: Slot 3, source 1 detects UPX TCC Soft Failure, sequence: 89 (0x8B593B05)
 
%RFGW-0-LINECARD_ERRMSG_EMERG: SLOT 3:LC_ERRMSG_FAILOVER_TRIGGER UPX Hi priority event (SET): module:1 idx:765 desc:UPX RF Power Level out of spec, type 11, data 0x8002b2fd
 

Conditions: This occurs when the pilot QAM is in shut state, followed by a line card reset or chassis reload.

Workaround: Shut the replicate QAM before attempting to shutdown the pilot QAM. To recover from this issue, unshut the pilot QAM and reset the DS384 card.

CSCuh51230

Symptom: The SNMP query on mpegOutputTSNumPrograms MIB object does not show the correct count of all programs.

Condition: This occurs for MPTS streams.

Workaround: Use the show cable video session command for the particular MPTS session to know about the number of programs carried in MPTS stream.

CSCuh51954

Symptom: The standby Supervisor card resets continuously after a line-by-line synchronization error is displayed by the active Supervisor card.

Conditions: RFGW is configured with RF Spanning with Pilot and Replicate Channels. In this event, configuring ASI interface to monitor replicate QAM interface will trigger the error.

Workaround: There is no service impact. Use ASI interface for monitoring the non replicate QAM interfaces (pilot channels). Use the ASI interface during maintenance windows.

CSCuh60698

Symptom: Consumed SPAN license are released after removing the replication group for the "force shut" channels.

Conditions: This issue occurs while removing the QAM replication group (QRG) of the channels that are shut forcefully. It is observed when the following sequence of commands are executed:

1. Configure Replication group.

2. Downgrade the license.

3. Remove replication group of force shut channels.

Workaround: Upgrade the license.

CSCuh70103

Symptom: If a PowerKEY encrypted session fails due to "blob failure", some of the commands do not display the failed state of the session. Specifically, the show cable video session and show cable video session remote gqi command do not display any problem with the failed session. The show cable video gqi sessions does display the Current State as "Fail to Black".

Conditions: This occurs in the case of an encryption "blob failure" which should be extremely rare in the field. The blob failure indicates that RFGW-10 can not decode the encryption information sent in the session create from the DNCS. This implies that there must have been a problem in the encrypted key exchange or handling in the DNCS or RFGW-10..

Workaround: Use the show cable video gqi sessions command for encrypted sessions to ensure that they are encrypted.

CSCuh74327

Symptom: A traceback is observed after the line card switchover.

%RFGW-3-UNEXPECTED: STANDBY:Db rx failed with reason 116 for VSCM SOURCE DB; db sync = DYNAMIC_SYNC, db op = DB_ADD, db key = [175.10.2.2, 235.0.1.11] observed while adding a backup source to a label after LCSO
 

Conditions: Supervisor card has table-based mutlicast sessions using multicast label. This issue occurs after you switch over a line card and add a backup source to the existing label.

Workaround: There is no service impact. Reload the standby Supervisor card for better operation.

CSCuh78899

Symptom: The following error with traceack occurs:

%RFGW-3-BULK_DNLD: Depi Session ID 1074069872 on Qam5/3.4 failed for Module
 

Conditions: This occurs when Supervisor has DEPI sessions created on DS48 line card and the DS48 line card is replaced with a DS-384 line card.

Workaround: This symptom doesn't exhibit operational impact. Remove the configuration of DS48 line card before replacing it with the DS384 line card to avoid this error.

CSCuh79353

Symptom: The following error is observed:

%RFGW_CSL-1-LIC_DB_GET_REC_FAIL: Slot:8 license DB record doesn't exist! Retry after bootup
 

Conditions: This occurs after the Supervisor card is switched over for the second time consecutively, right after the standby Supervisor card boots up and is in hot standby state on a large scale test bed..

Workaround: Wait for 5 to 10 seconds after the standby Supervisor card boots up, to ensure that the database is synced rom the active to the standby Supervisor card before switching over the Supervisor card again. The Supervisor card must be switched over again to recover from this error.

CSCuh79783

Symptom: The standby Supervisor card is out of synchronisation and the Supervisor card switches over causing the errors along with traceback.

vscm_source_map_id_get -> Unable to locate source [46.1.42.5, 0, 239.1.1.49, 5245] from database
vscm_source_link_map -> Unable to locate source from database
 

Condirions: This occurs while the RFGW-10 is churning the sessions in the background, and the following steps are executed:

  • Line card is switched over from line card 3 to line card 11 using redundancy commands.
  • The supervisor cards are switched over many times after line card 3 is in hot standby mode.
  • After eight Supervisor card switch-overs, the line card 11 is switched back to line card 3.

Workaround: Before any Supervisor switch-overs, reset the standby Supervisor card to enable it to set a fresh database checkpoint from the active Supervisor card.

CSCuh79811

Symptom: On a rare occasion, the standby Supervisor card resets after the redundancy reload shelf command is executed.

Conditions: This occurs when the following specific series of steps performed on Supervisor card:

1. Configure remote unicast sessions with Annex A.

2. Perform supervisor switch-overs.

3. When the redundancy reload shelf command is used at this juncture, the active Supervisor card switches over as standby.

Workaround: There is no service or functional impact. Reload the standby Supervisor card.

CSCuh80593

Symptoms: Bulk synchronization fails. PRC errors are seen on active Supervisor card and the standby Supervisor card resets before going into RPR mode. The PRC error is as follows:

Config Sync: Bulk-sync failure due to Servicing Incompatibility. Please check full list of mismatched commands via:
show redundancy config-sync failures mcl
interface Qam9/1.1
! <submode> "subinterface"
- cable downstream interleaver-depth I128-J1
! </submode> "subinterface"
interface Qam9/1.2
! <submode> "subinterface"
- cable downstream interleaver-depth I128-J1
 

Conditions: This occurs when the rf-profile is changed from Annex-B to Annex-A and the Supervisor card is switched over.

Workaround: Reset the standby Supervisor card after trying to change the rf-profile.

CSCuh82418

Symptom: In a very very rare occasion, the following error and traceback occurs on the standby Supervisor card:

%SYS-3-INVMEMINT: Invalid memory action (free) at interrupt level
 

Conditions: This occurs when the RFGW-10 chassis is reloaded using the redundancy reload shelf command.

Workaround: This symptom does not exhibit any service/operations impact observed and may be ignored. Traceback is seen while resetting the standby Supervisor card as part of chassis reload. As standby Supervisor is resetting on its own, no issues occur in operation.

CSCuh85162

Symptoms: Traceback observed on active Supervisor card.

vscm_session_update_lc_session_id -> Missing a create checkpoint from active SUP for session 276567536
vscm_session_set_matching_lc_session_id -> Unable to get lc session id 5377 from free list on slot 6 carrier_id 133 for session 411374849
 

Conditions: This occurs on the standby Supervisor card when the chassis is fully loaded, the line cards are switched over several times, followed by a Supervisor card switch over, with high churn rate for both VOD and SDV in the background.

Workaround: Reset the standby Supervisor card before the Supervisor card switch over, to prevent sessions deletion when standby Supervisor card becomes active.

CSCuh86237

Symptom: Adding the line card to the lcred group after inserting packets results in line card state progression failure and the secondary line card resets with following errors:

%LCRED-3-LC_STATE_PROG_FAILED: Redundant Line Card 11 (idx
Router#=11) state progression failure. Line card will be reset due to Platform Failure to download config to Linecard. (State: Active,Event: Cfg Dnld)
Defaulting the Qam interface having packets inserted results in errmsg
%RFGW-3-LINECARD_ERRMSG_ERR: SLOT 9:LC_ERRMSG_VIDEO_CAROUSEL_NOT_IN_QAM CHANGE_CRSL: CRSL 1, QAM 9
Inserting more than 1024 packets resutls in tracebacks
vscm_pi_session_incr_session_count -> total PI mpeg counts on slot 4 = 1029
 

Conditions: This occurs when inserting 48 packets ids and then adding the line card to an existing 1:N lcred group. If the QAM channel is in shut state, with no frequency assigned , the show cable video packet all command output shows the Packet in ON State. Defaulting the QAM channel with packets inserted, results in the error messages. Inserting more than 1024 packets results in tracebacks.

Workaround: Configure LCRED group before inserting packets. Do not default the interface having packets inserted in them.

CSCuh87092

Symptom: DS_Span License and DS_License shows zero consumed license.

Conditions: This occurs when the following steps are executed:

1. DS384 primary card is reset which makes the secondary line card to become active.

2. After about 3 1/2 minutes, reset the secondary line card in the redundancy group (double-fault scenario). This issue doesn't happen if the secondary is reset earlier during the primary restart.

3. After primary finishes going operational, the consumed licenses are incorrect (listed as zero).

Workaround: Following a linecard switchover from the primary line card, wait for it to become operational before resetting the secondary linecard. To recover: Wait until the peer is fully operational and do an additional linecard switchover to recover. The recovery should be done before an SSO switchover takes place to prevent affecting service. This is not normally service-affecting unless an SSO switchover is done before doing the workaround recovery.

CSCuh87115

Symptom: NULL output when the show depi tunnel verbose command is used.

Conditions: This occurs on the Supervisor card which has DEPI remote learn mode configured.

Workaround: Re-issue the same command to see the correct output.

CSCuh90967

Symptom: On a rare occasion, the active supervisor resets on its own due to RTSP process crash and triggers supervisor switchover.

Conditions: This occurs on a Supervisor card which has ERMI sessions in a 1:N LCRED system where back to back line card switch-overs (from LC3 to LC11 and LC11 to LC3) cause supervisor reset. This might happen in Large scale setup.

Workaround: Provide enough time between back to back line card switchovers to avoid the Supervisor card reset.

CSCuh91236

Symptom: Video session on pilot QAM cannot be configured using video GUI.

Conditions: This occurs while configuring video session under pilot QAM channel in video local session page (RF Spanning enabled). IThe following error message is displayed:

Remove the pilot qam from QRG before making a change
 

Workaround: Configure the session first and then add QRG before attempting this configuration on GUI. After encountering this scenerio, configure the session on CLI.

CSCuh92775

Symptom: On a rare occasion, the following error occurs on a Supervisor card console:

%SCHED-3-THRASHING: Process thrashing on watched queue 'Helper [1] Event Queue'. -Process= "RFGW GQI Helper 1", ipl= 2, pid= 143
 

Conditions: This occurs on the Supervisor which has GQI sessions created and deleted one after the other repeatedly

Workaround: There is no service or functional impact. Therefore, no workaround is required.

CSCuh94947

Symptom: On a very very rare occasion, an RFGW-10, which has huge number of Video & DEPI sessions configured, a Supervisor switchover occurs. Aline card crashes and leads to a line card switchover. When standby line card takes over, some DEPI sessions stay in IDLE state.

Conditions: This occurs RFGW10 chassis fully loaded with ten line cards configured in 9:1 linecard Redundancy mode and performing the following actions on it. Multiple Supervisor SSOs with SDV & VOD session creations/deletions happening continuously.

Workaround: Two or more SSOs of the Supervisor cards might recover the lost DEPI sessions.

CSCuh95185

Symptoms: Supervisor card experiences following config sync failure and followed by reset on its own:

Config Sync: Starting lines from PRC file:
interface Asi3/13
! <submode> "interface"
- cable monitor rf-port 5 channel 2 after-core-enc
! </submode> "interface"
 

Conditions: This occurs when the ASI interface is configured with the LCRED, to monitor QAM RF channel, and the Supervisor card is switched over.

Workaround: Remove the configuration from ASI, switch over the Supervisor card and reconfigure LCRED on the newly active Supervisor card. Preferrably ASI interface should be used only for debugging for the maintenance window.

CSCuh96460

Symptoms: On a very rare occasion, the following errors and tracebacks are observed:

“%SCHED-7-WATCH: Attempt to monitor uninitialized watched boolean (address 0). -Process= "GalRedMsgProc", ipl= 0, pid= 71
%SCHED-3-STILLWATCHING: Process still watching boolean Wait for get_system_version_resp -Process= "GalRedMsgProc", ipl= 0, pid= 71”
 

Conditions: This occurs when the RFGW-10 chassis is fully loaded and configured with 9:1 line card redundancy and multiple SSO events of Supervisor cards.

Workaround: There is no service or functional impact. Therefore, no workaround is required.

CSCuh96476

Symptoms: The following errors and tracebacks are observed:

“SYS-3-CPUHOG: Task is running for (2100)msecs, more than (2000)msecs (8/8),process = RF Slave Main Thread”
 

Conditions: This occurs when the chassis is fully loaded with 10 LCs and huge number of DEPI and Video sessions., and multiple SSO events of Supervisor cards.

Workaround: There is no service or functional impact.

CSCuh96667

Symptom: On very very rare conditions, some video sessions continue to be displayed as ‘active’ even while the input bitrate drops to zero, through show cable video session command.

Conditions: This is observed on RFGW-10 chassis when it is configured with unicast video sessions. When the unicast streaming is stopped manually, the input bit rate gradually drops to zero.

Workaround: This is only a display error and there is no service impact.

CSCuh96957

Symptoms: In a very rare scenerio, the following errors and tracebacks are observed:

“%RFGW-3-UNEXPECTED: STANDBY:Db rx failed with reason 117 for Data Session DB; db sync = DYNAMIC_SYNC, db op = DB_UPDATE, db key = Session ID : 1074594565”
 

Conditions: This occurs on fully loaded RFGW10 Chassis and 9:1 LC Redundancy with huge number of Video and DEPI configured and when multiple SSO events of Supervisor cards occur.

Workaround: There is no service impact. Therefore, no workaround is required.

CSCuh98507

Symptoms: DS_License count increases even when lesser number of DS channels are consumed.

Conditions: This occurs on RFGW0 with replication channels confiigured with Downstream QAM channels and when the following sequence of events occur on the chassis.

1. Linecard switches over from line card 3 to line card 11

2. Remove all replication channels by deleting replication groups

3. Switch ove the Supervisor card

4. Revert back to line card 3.

At this point, we see that line card 3 has more licences consumed, upto 384 though we configured fewer QAM channels..

Workaround: Switch over the line card using r edundancy linecard-group switchover from the <slot>.

CSCuh99000

Symptoms: On a very rare occasion, some of the STBs show no video for a brief period of time, since one of line cards might have reset due to bb_video process crash and should have triggered line card switchover (if line card redundancy is configured)

Conditions: This occurs on a RFGW10 chassis which has GQI & ERMI sessions and performing back-to-back Supervisor card switchovers while running SDV channel change stress test.

Workaround: Wait until Video is available on QAM output with no line card redundancy. Ensure that line card redundancy is configured.

CSCuh99434

Symptom: Random DEPI data plane sessions are lost after a RFGW SSO switch over when running the Cisco IOS Release 12.2(33) SCH.

Conditions: The problem only occurs when running the Cisco IOS Release 12.2(33) SCH, and you have Control Plane DEPI configured.

Workaround: Toggle the DEPI ingress interface to DOWN and then UP, to force renegotiation of the data plane sessions.

Preforming an SSO switchover on the RFGW may trigger the issue again.

Additional Information:

Toggling the DEPI ingress interface to recover the sessions will cause all the modems on the sessions, running through that interface, to fall offline briefly.

CSCui01526

Symptom: Correct depi-tunnel destination IP address using GUI is not correctly assigned.

Conditions: This occurs when using GUI for configuring DEPI tunnel destination IP.

Workaround: Configure DEPI tunnel destination IP through CLI.

CSCui01581

Symptom: Firmware/Serial number may not be shown in SNMP

walk

Conditions: This occurs when running SNMP walk for ISO MIB.

Workaround: Use relevant show command.

CSCui04646

Symptom: Some of encrypted sessions are displayed as Encrypt/No even though the sessions are actually encrypted.

Conditions: This occurs when using GUI to view the GQI sessions configured in the chassis.

Workaround: Use the show cable video sess remote gqi all command for viewing correct information.

CSCui15834

Symptom: The following error message is displayed:

%RFGW-3-LINECARD_ERRMSG_ERR: SLOT 12:LC_ERRMSG_IPC_SEND_FAILED bb_depi RPC MSG_TYPE_MB_QUERY_DEPI_SESSION_STATE reply - error timeout
 

Conditions: This occurs after line card high availability activation twice and SSO per iteration, and requires more than 5 iterations to encounter this error.

Workaround: There is no service or operational impact. All the depi and video sessions are active and modems remain online. Therefore, no workaround is required.
