Chapter 3 General Configuration and Monitoring 58 78-4025112-01 Rev H0 Output Monitoring The Output Monitoring page provides information related to how transport streams on the input are bound to QAM resources on the output. The Details button under the Input parameter provides additional information on the input stream associated with a particular output session. See the following screen. Parameters The following table describes the Output parameters. Parameter Description Session ID The ID of the output session. Type Refers to Session Type (SPTS, MPTS, Plant or Data). RFGW QAM Channel Output QAM channel for a particular session ID. SRM QAM Channel The channel identification for the SRM. Output Bitrate Output bitrate of a session. Status Describes session status. Unbound: The session is not active. Bound: The session is active and bound to QAM resources on the output. Bad input: The input stream associated with this stream is invalid. GbE Port The GbE port of the input stream associated with an output session. Destination IP Address Destination IP address of the stream. For multicast streams, it is the multicast address. UDP Port UDP port of the input stream associated with a session. Output Refers to output program number, PMT PID, and PCR PID for a session. Input Provides details on the input stream associated with an output session.
Monitoring the RF Gateway 1 78-4025112-01 Rev H0 59 Session Refresh The RFGW-1 generates an input pid conflict alarm (Alarms/Events section) if any ES or the PMT pid in an MPTS is the same as a pid already in use in the same MPTS. Recall that it is the users responsibility to ensure that the pids in an MPTS are unique. To clear the pid conflict alarm it is necessary to not only resolve the input pid conflict at the source e.g. the DCM but also to refresh the associated sessions as seen in the following screen shots. Recall that the pid conflict is to be resolved before refreshing the session. Once input PID conflict is detected, the services that are involved in the conflict will not be routed to the output. Session Refresh Procedure Find out the IP address of the MPTS with the conflict: Verify that the MPTS displays the input pid conflict by viewing the input monitor page: Hunt for the output session with the pid conflict by searching through the output monitor detail pages:
Chapter 3 General Configuration and Monitoring 60 78-4025112-01 Rev H0 Click the Display Session button at the bottom of the output monitor details page to display the sessions that are to be refreshed. Click the Session Refresh button at the bottom of the output monitor details page to clear the pid conflict alarm and to activate the stream. Recall that refreshing all sessions will cause a brief interruption in service of the associated output carrier. A dialog box will appear shortly after clicking the Refresh All Sessions button:
Monitoring the RF Gateway 1 78-4025112-01 Rev H0 61 Once the PID conflict is resolved at the headend device, then after refreshing the session, the PID conflict alarm will be cleared. The state in the Input Monitor page will also change to Active only after the session refresh is completed. Even if the input PID conflict is resolved, but the session refresh button is not clicked, then state in Input monitor page will remain as Input PID conflict Data Monitoring The Data Monitoring page provides information related to how data streams on the input are bound to QAM resources on the input. The following illustration shows the Data Monitoring screen. Parameters The following table explains the Data parameters. Parameter Description Output Channel The output channel for a data stream. Type Type of data stream (DOCSIS MPT with UDP, DOCSIS MPT without UDP, DOCSIS PSP with UDP, DOCSIS PSP without UDP, MPEG, DATA). GbE Input GbE input associated with the data stream. Output Bitrate Bitrate of the data stream. Destination IP Destination IP of the data stream. UDP/DEPI Destination UDP or DEPI session ID for the data stream. Status Status of the data stream (Stream Active, Stream Inactive).
Chapter 3 General Configuration and Monitoring 62 78-4025112-01 Rev H0 Parameter Description Synch State Describes whether the data flow is a primary flow containing DOCSIS synch messages or a non-primary flow that does not contain sync messages. Synch Counter The number of sync messages received in a primary flow. DTI Monitoring DTI Monitoring provides monitoring of status and statistical information on the DOCSIS Timing Interface. The following parameters are available. Active Port Client Status DTI Port Status (for each port) DTI Statistics The following screen shows DTI monitoring. For more information on DTI statistics, refer to Basic M-CMTS Data Specific Operation (on page 113).
Monitoring the RF Gateway 1 78-4025112-01 Rev H0 63 Resource Utilization CPU and memory utilization are displayed for the operator in real time for monitoring. SNMP Configuration SNMP configuration is done on the GUI using the System/SNMP & Traps page. There are two configurations as shown in the examples below. The first configuration is for software versions prior to 2.01.09. Refer to the screen below. In this configuration, three community strings can be set. The Read string is the get community string. The Write string is the set community string and the Trap string is the trap community string. In this configuration, all traps are SNMPv1. Up to 5 traps can be enabled/disabled.
Chapter 3 General Configuration and Monitoring 64 78-4025112-01 Rev H0 The second configuration is for software versions 2.01.09 and later. Refer to the screen below. In this configuration, the Read string is the get community string. The Write string is the set community string. Traps can set to disabled SNMPv1 or SNMPv2 for each receiver. Each trap receiver can have its own trap community string.
Fault Management of the RF Gateway 1 78-4025112-01 Rev H0 65 Fault Management of the RF Gateway 1 The RF Gateway 1 supports automatic detection and user notification of changes in the system. Changes may be classified as either Events or Alarms. Alarms carry a state while events are important instances that occur in time and are reported. For example, Link Lost and Link OK are two well-defined states and are associated with an alarm. Events Startup, Configuration Backup, and Second Power Supply Inserted do not have a state but are important events reported by the system. System Alarms System Alarms are conditions with state that occur on the system that the user may want to be aware of. The RF Gateway 1 provides user notification of changes in alarm state. These notifications can be via SNMP traps, system log or the front panel fault LED. System alarms can not be masked or filtered and will always be indicated on the system. The default alarms supported by the system are defined in the alarm configuration area of the database. The default alarm configuration parameters include items such as alarm label, severity, mask, threshold, and enabled notifications. These parameters are defaults and are not configurable through the web interface. While active, the system maintains additional information on each of the alarms such as alarm originator, state, instance, and other descriptive details including triggering threshold, actual value, and units. Alarms have two possible state values, Alarm and Clear. Each alarm has two possible severity levels, Critical or Major. The supported alarms are described in the following table. Name Severity Description Power On Self Test Critical A failure during power on self test has been detected. GbE Port Link Critical A GbE port has changed state. UDP Traffic Major Complete loss of UDP traffic has been detected. Fan Failure Major One of the four chassis fans RPM is measuring below threshold. FPGA Temperature Major A FPGA board temperature has exceeded the threshold. Power Supply Shutdown Critical A power supply has indicated an imminent shutdown. DTI Port Link Critical A DTI port has changed state. Power Supply Voltage Critical One or more power supply voltages is performing outside of the acceptable threshold. Continuity Count Error Critical MPEG continuity counts have been detected on one or more elementary streams.
