Information About Video Notifications

The Cisco cBR-8 router sends SNMP trap notifications about video related events.

Overview of Video Notifications

The Cisco cBR-8 router sends SNMP trap notifications for the following events:

  • When connection is lost or when connection is re-established between Cisco Edge QAM Manager (CEM) application and Cisco cBR-8 router.

  • When connection is lost or when connection is re-established between D6 Discovery Protocol servers and Cisco cBR-8 router.

  • When connection is lost or when connection is re-established between Cisco cBR-8 router and the GQI Edge Resource Manager.

  • When connection is established between CEM and Cisco cBR-8 router for 180 seconds, but Cisco cBR-8 router does not receive ECM templates from the CEM. Cisco cBR-8 router also sends a notification when it receives ECM templates from CEM.

  • When QAM bandwidth exceeds the specified maximum bandwidth of the QAM channel. Cisco cBR-8 router also sends a notification when the QAM bandwidth returns to within the specified bandwidth.

  • When two or more PIDs have the same number in a QAM channel.

  • When two or more programs have the same number in a QAM channel.

  • When connection is lost or when connection is re-established between the DVB ECMG server and Cisco cBR-8 router.

  • Loss of connection or reconnection between the DVB EIS client and the Cisco cBR-8 router.

  • When the input stream from the primary source for a video session is lost, and the backup source is now in the active state. If the ingress video stream packet has CC (Continuity Counter) errors as per the CC threshold and report-interval configuration.

  • When no traffic is seen within the OFF-timeout period for a video session, and the session gets moved to an OFF state and stays OFF for 30sec. If the ingress video stream does not have the PMT table.


Note

All cable video traps sent out are conform to the SCTE-HMS-ALAMRS-MIB standard (ANSI/SCTE 38-2 2011).

How to Configure Video Notifications


Note

To know more about the commands referenced in this module, see the Cisco IOS Master Command List.

Configuring SNMP Notification Host

To configure remote SNMP notification host on the Cisco cBR-8, follow the steps below: 

Router> enable
Router# configure terminal
Router(config)# snmp-server host ip-address [version {1 | 2c | 3 [auth | noauth | priv]}] community-string [udp-port port-number]

UDP port 162 is the default port to receive SNMP notifications.

Configuring SNMP Notification Message Queue Length

To configure SNMP message queue length, follow the steps below:

Router> enable
Router# configure terminal
Router(config)# snmp-server queue-length <1-5000>

The recommended message queue length is 5000.

Configuring Video Notification

To enable all video notifications, follow the steps below:

Router> enable
Router# configure terminal
Router(config)# snmp-server enable traps video-cable

To enable one or more specific video notifications, follow the steps below:

Router> enable
Router# configure terminal
Router(config)# snmp-server enable traps video-cable [video_notification]

Configuration Examples for Video Notifications

Example 1: Configuring Remote SNMP Notification Host

Router> enable
Router# configure terminal
Router(config)# snmp-server host 10.143.25.185 version 2c public udp-port 1602

Example 2: Configuring SNMP Notification Message Queue Length 

Router> enable
Router# configure terminal
Router(config)# snmp-server queue-length 5000

Example 3: Enable Specific Video Notifications 

Router> enable
Router# configure terminal
Router(config)# snmp-server enable traps video-cable cemconn pmeecm qamovr

Example 4: Disable Specific Video Notifications 

Router> enable
Router# configure terminal
Router(config)# no snmp-server enable traps video-cable cemconn pmeecm qamovr

Example 5: Enable input-stream-failure error reporting with report-interval

Router> enable
Router# configure terminal
Router(config)# cable video
Router(config-video)# report-stream-error input-stream-failure report-interval 25

Example 6: Enable Continuity Counter error reporting on the chassis level with CC threshold and report-interval

Router> enable
Router# configure terminal
Router(config)# cable video
Router(config-video)# report-stream-error cc-error report-interval 15 threshold 10

Configuring CC-ERROR Reporting

Use the report-stream-error cc-error command under cable video to enable CC-ERROR reporting on the chassis level. The CC_ERROR monitor is disabled by default, you can enable the CC-ERROR monitor using the following commands.

  • report-stream-error cc-error report-interval interval : Event report interval in minutes. The default value is 10 mins.

  • report-stream-error cc-error syslog enable : Syslog notification for Error events.

  • report-stream-error cc-error threshold cc-error-count : Threshold value to report the event. The default value is 5.

Enabling CC-ERROR Monitoring

The cc errors are only monitored if this command is configured:

Router(config)#cable video
 Router(config-video)#report-stream-error cc-error

Once this command is configured, cc-error set/clear messages are sent using the IPC message. If the command is not configured, it does not send any IPC message.

Enabling CC-ERROR Syslog

CC-ERROR messages are sent to syslog only if this command is configured:

Router(config)#cable video
Router(config-video)#report-stream-error cc-error syslog enable

  • If the stream has a continuous cc-error, then only one message for the corresponding stream is sent. Here is a sample snippet of the message: 

    ...
Jun 19 18:05:11.776 IST: %VSESS-3-STREAM_ERROR: R0/0: led: 1 Slot: 3 CC_ERROR:SET:3:6: 
Reported on source 175.2.2.2:232.2.1.1:0
...

  • The CC_ERROR CLEAR message is sent after the stream recovers from CC_ERROR. Here is a sample snippet of the message:

    ...
Jun 19 18:05:16.765 IST: %VSESS-3-STREAM_ERROR: R0/0: led: 1 Slot: 3 CC_ERROR:CLEAR:3:0: 
Reported on source 192.2.2.2:232.2.1.1:0
...

Threshold Control

Configure the threshold value using the following command.

Router(config)#cable video
Router(config-video)#report-stream-error cc-error threshold cc-error-count

The default threshold value is 5. The valid range is 1 to 65535.

For example, when the threshold value is configured as 10, then if the CC_ERROR count value is greater than 10 then it sends the cc_error SET message.

Report-interval Control

Configure the report-interval value using the following command.

Router(config)#cable video
Router(config-video)#report-stream-error cc-error report-interval minutes

The default report interval value is 10. The valid range is 1 to 65535.

For example, when the report-interval value is configured as 45 and CC_ERROR is set and the clear message hits multiple times then

  • all set/clear messages are not sent.

  • only one set/clear is sent, and the number of set/clear messages are calculated. Here is a sample snippet of the message:

    Jun 19 18:05:11.776 IST: %VSESS-3-STREAM_ERROR: R0/0: led: 1 Slot: 3 CC_ERROR:SET:3:6: 
Reported on source 175.2.2.2:232.2.1.1:0

Jun 19 18:05:16.765 IST: %VSESS-3-STREAM_ERROR: R0/0: led: 1 Slot: 3 CC_ERROR:CLEAR:3:0: 
Reported on source 175.2.2.2:232.2.1.1:0

  • After 45 minutes, only one info message is sent, that shows how many times set/clear CC_ERROR has occurred during the 45-minutes interval. Here is a sample snippet of the message: 

    Jun 19 18:50:11.809 IST: %VSESS-3-STREAM_ERROR: R0/0: led: 1 Slot: 3 CC_ERROR:INFO:3:0: 56 
events occurred during last report interval(45 min) for source 175.2.2.2:232.2.1.1:0
