Search for a CM by entering the MAC address. This initiates a SNMP request to the device and results in navigation tabs populated with CM data. The data is a one-time snapshot of the device. If you want a new real-time snapshot, click Refresh.

NOTE: If you enter a MAC address of a modem that doesn't support DOCSIS 3.1, only the Overview, SC-QAM, and Historical tabs will appear.

    • CM CPE IPs Learned — List of physical (MAC) addresses of customer premise equipment, such as MTA, which has been connected to cable modem since its last reboot. Cable modem itself may have more than one MAC address which may show up in this list.
  • CPE Interfaces — Available interfaces for CPEs to connect to. Describes the type of interface (ETHERNET/USB/etc) and the status (up/down/inactive/etc).
  • Configuration
    • CM IP Address (v4) — Current IPv4 address of the cable modem as assigned by the DHCP server.
    • CM IP Address (v6) — Current IPv6 address of the cable modem as assigned by the DHCP server.
    • CMTS Name — IP address of the CMTS.
    • CM Sys Description — Lists cable modem software and hardware versions, manufacturer, and related information.
    • CMTS Sys Description — Lists CMTS software and hardware versions, manufacturer, and related information.
    • Fiber Node — Specifies the Fiber Node ID, or location. For example, Lowell.
    • Hierarchy Path — Specifies where in the Hierarchy a modem is located.
      NOTE: Fiber Node ID and Hierarchy Path are provided by customers during ingest, and are not detected automatically by the system, such as the CMTS Name.
    • CM Config File — The name of the configuration file that was used to configure this cable modem during the provisioning process.
    • CM QoS Version — Current version of DOCSIS used to register on this CMTS. Valid values for this metric are DOCSIS 1.0 or DOCSIS 1.1.
  • Status
    • CM Status — The registration status of the cable modem on the CMTS. Only the value 'operational' represents a fully functional cable modem. Other values indicate that registration is still in progress.
    • In Home — The In-Home feature identifies potential issues with a specific cable modem rather than the HFC plant. For example, a loose connector or damaged cable might affect only one modem or service location. The likelihood that a particular cable modem is having In-Home issues is calculated and appears as a percentage value (or score) If the configured threshold is crossed, the icon turns orange.
    • Highest Threshold Crossing — The highest overall alarm severity, which is measured by scanning across a cable modem, all KPIs, and all frequencies, excluding Partial Channel. Partial Channel values are not included in the highest threshold crossing calculation. Analyze also includes OFDM/A threshold data.
    • Partial Service Count — A summary of partial service counts classified by channel type. The colored icon indicates the following:
      • Green — no channels in partial service
      • Yellow — only SC-QAM channels in partial service
      • Red — OFDM/A channels in partial service (includes both SC-QAM and OFDM/A)
    • CM Uptime — The amount of time elapsed since the cable modem's last reboot.
    • CMTS Uptime — The amount of time elapsed since the CMTS was last rebooted.
    • Time Since Last Update to CM Status — The amount of time elapsed since the cable modem status last changed.
    • CM MAC Interface Downstream Bitrate Kbps — The current rate of downstream traffic at the modem.
    • CMTS QoS Downstream Bitrate — The total modem downstream service flow traffic rate, after payload header suppression, as reported by the CMTS.
    • CM MAC Interface Upstream Bitrate Kbps — The current rate of upstream traffic at the modem.
    • CMTS QoS Upstream Bitrate Kbps — The total modem upstream service flow traffic rate, after payload header suppression, as reported by the CMTS.
    • CM Number of Invalid MAPS — Number of corrupt or otherwise invalid messages describing allocation of upstream bandwidth. This is a condition that afflicts mainly older modems.
    • CM Number of Downstream Sync Losses — The number of sync losses in the downstream indicates how often the CM has lost the synchronization with the signal sent from the CMTS. This value can increase in case of downstream plant problems but should be stable during normal operations. If the value increases, check the Downstream RX power and Downstream SNR.
    • CM Latency (ms) — The response time for a ping operation to a cable modem. Click Refresh to start another ping operation.
    • CMTS Latency (ms) — The response time for a ping operation to a CMTS. Click Refresh to start another ping operation.
    • CMTS CPU Utilization (%) — Utilization of a CMTS CPU. The definition varies depending on the CMTS vendor. This can be the utilization of the CPU that performs primary routing functions, or it might be an average of the utilizations for all the CMTS CPUs. For some CMTS vendors, high CPU utilization adversely affects the performance of cable-modem data forwarding. This is a threshold value and is displayed in different colors that represent the severity.

      Data for this status item is also available on the Historical tab. By its nature, modem- and channel-based interactions do not apply to graphs of this item.

  • Service Configuration — Returns CM configuration settings, which are set during the installation and configuration process and are stored in the config file.
    • CM Downstream Max Kbps — The maximum rate of data transfer from the CMTS to the cable modem (downstream) in kilobits per second (Kbps). A higher number indicates that the user is consuming more data.
    • CM Upstream Max Kbps — The maximum rate of data transfer in kilobits per second (Kbps) from the cable modem to the CMTS (upstream). A higher number denotes a greater usage of data by the subscriber.
    • CM Downstream Priority — Downstream traffic priority assigned to the service level. Higher numbers indicate higher priority. This priority must only be used to differentiate service flows with identical Quality of Service (QoS) parameter sets.
    • CM Upstream Priority — Upstream traffic priority assigned to the service level. Higher numbers indicate higher priority. This priority must only be used to differentiate service flows with identical Quality of Service (QoS) parameter sets.
  • Flap Information — Flap is a term applied to a cable modem intermittently going on and offline. If a cable modem shows data in the flap table, it has been registered by the CMTS because of a frequent number of flaps. Flaps can happen because of HFC network issues or because of problems with the cable modem itself.
    • Time of Last Flap — The time of the most recent recorded cable modem flap.
    • Last Modem State — The previous state of the modem before its current state. The state values returned are the CMTS vendor-specific extended modem state values, where supported.
    • Total — Total number of flaps for this cable modem. This is a running counter maintained by the CMTS and incremented each time a modem flaps.
    • Reinitializations — The number of times that a cable modem registers more frequently than expected. When a CM initially ranges, reboots, and initially ranges again within a specified insertion time, this counter is incremented.
    • Periodic Ranging Hit/Miss — The percentage of the cable modem's periodic station maintenance message that the CMTS does not receive (misses) out of the number of times the CMTS receives (hits) the periodic station maintenance messages. A high Miss/Hit Ratio may indicate problems with the network such as an intermittent upstream (cable modem - to - CMTS) signal, or bursts of undesired noise on the network. A low or zero Miss/Hit Ratio indicates the CMTS is receiving ranging attempts from the cable modem, or cable modem-to-CMTS communication is satisfactory or better.
    • Power Adjustments — The number of times this cable modem was requested to make an excessive transmit power level adjustment to accommodate the CMTS receive power requirements. The threshold for what constitutes excessive power level adjustments is configured in the CMTS.
    • CRC Errors — Count of data packets with Cyclic Redundancy Check errors, which indicate corruption of the information in the packet.

      The Analyze application supports display of error codes. For example, if you see --? next to a metric, you can hover your mouse over the question mark and an error message will display.

      If a metric cannot be determined, the field should display N/A. If a metric is OK or there is no Status field, the value of the metric is displayed.

NOTE: See Analyze modem view - Restricted Access for information on what data is redacted when restricted access is applied to a user.
