Casa Systems C100G

The Casa Systems C100G connector uses SNMPv2 to monitor and control the Casa Systems C100G. This device is a CCAP, which means it combines the functions of a CMTS and edge QAM into a single platform.

About

The Casa Systems C100G is a chassis that has separate modules for downstream and upstream traffic, switching, etc.

Configuration

Connections

SNMPv2 main connection

This connector uses a Simple Network Management Protocol version 2 connection and requires the following input during element creation:

SNMP CONNECTION:

  • IP address/host: The polling IP of the device, e.g., 10.11.12.13.

SNMP Settings:

  • Port number: The port of the connected device, by default 161.
  • Get community string: The community string in order to read from the device. The default value is public.
  • Set community string: The community string in order to set to the device. The default value is private.

SNMPv2 spectrum analyzer connection (range 2.1.0.1)

To use the spectrum analyzer (range 2.1.0.1), configure a second SNMP connection using the same values as for the primary SNMP connection.

SNMPv2 connection (range 5.0.0.1)

When you use the custom version, you should set the timeout of the element to 10 seconds in order to avoid unnecessary timeouts.

If a restart of the element is necessary, stop the element and wait a few seconds before restarting it; there can be blockages in the equipment if it is not allowed to finish previously requested actions.

Usage (Range 1.0.0.x and 2.0.0.x)

General

This page displays general information about the device. This information is divided into several groups:

  • General Info: System information, such as the System Name, System Up Time, etc.
  • Cable Modems Info: Information about the cable modems managed by the device.
  • Upstream/Downstream Info: Capacity and bitrate upstream and downstream information.

Spectrum Settings

This page allows you to configure the spectrum analyzer interface.

Three options for tracing can be selected with the Measurement Trace Selection parameter:

  • Absolute: Based on physical type interface power values.
  • Relative: Based on logical type interface power values.
  • Disabled: Default option. Disables the data tracing process.

In combination with the sweep time, the Retrieval Time Control adjusts the time to acquire the data via SNMP using a second connection.

Below this, you can select an interface based on what is selected for the Trace Selection parameter.

Configuration

This section contains two pages: one for the upstream and one for the downstream channel configuration:

  • The Configuration -- Upstream Channels page displays the Configuration - Upstream Channels table. This table contains the configuration data for the different upstream channels of the Casa Systems C100G, for example the US Frequency, US Width, etc.
  • The Configuration -- Downstream Channels page is similar to the Configuration -- Upstream Channels page but displays the Configuration - Downstream Channels table. This table contains all configuration data for the downstream channels on the Casa Systems C100G.

Measurements

This section also contains a page for the downstream channels and one for the upstream channels:

  • The Measurements -- Upstream Channels page displays the Measurements - Upstream Channels table. This table contains the measurement information for the upstream channels. The table has an entry for each upstream channel. The US CM Total column will for example display how many cable modems use that particular interface.
  • The Measurements -- Downstream Channels page is very similar to the Measurements -- Upstream Channels page, but this page displays the Measurements - Downstream Channels table, which displays the downstream measurements.
  • The Measurements -- Ethernet and Configuration -- Ethernet page displays the Gigabit Interface Table. This table contains the Ethernet interfaces to monitor the traffic used.

Performance

This section has several tables distributed over different pages:

  • Performance: This page contains the Power and Fan Status Tables.
  • Temperature: This page shows the Temperature Status Table.
  • CPU Status: This page displays the CPU Status Table.
  • Memory Status: This page contains the Memory Status Table.

Extra

This section consists of several pages: Cable Modems, Service Flow, Ping Function and Flap List.

  • The Cable Modems page can be used to access information about the cable modems managed by the Casa Systems C100G. This page displays the CM Table and CM Registration Table. You can find more detailed information by clicking the CM CPE or CM Status Ext page buttons.

  • The Service Flow page displays the Service Flow Table. This table describes the set of DOCSIS-QOS Service Flows in the managed device.

  • The Offload US/DS Channels page can be used to offload the interface data to a semicolon-separated text file. The location and the interval to create these files can be specified on this page. This page also contains page buttons that can be used to access more detailed information about the interfaces, modules, etc. The Redetect Config button can be used to clear the upstream or downstream information from the different tables.

  • The Offload Topology page can be used to offload 6 topology files: CM.csv, CMTS.csv, DSSG.csv, FNCMTS.csv, SG.csv and USSG.csv. These topology files contain information about the Cable Modems (CM.csv), Fiber Nodes (FNCMTS.csv), Service Groups (SG.csv) and DS/US Service Groups (USSG.csv and DSSG.csv) managed by the Cable Systems C100G. When the button Get Topology is pressed, the 6 files are created and stored in a folder with the name of the CMTS, inside the directory specified in the parameter Local Location.

  • The Ping Function page can be used to ping devices. If Ping Query is Enabled and the IP addresses are filled in, the devices will be pinged and the status and RTT of the ping will be displayed. You can also provide a file containing the IP addresses of the devices you want to ping. In that case, the connector will ping the IP addresses in the provisioning file.

  • The Flap List page displays the Flap List Table. This table displays more information about some of the cable modems managed by the Cable Systems C100G. The Flap List Table displays for example the number of Flap Hits, Flap Misses, etc.

  • By default, the Flap List table is not polled by the connector, but polling can be enabled via the Flap List Control page. To access this page, click the Flap List Control page button. The Flap List Control subpage will also display extra information about the Flap List, like the Flap List Current Size and some Thresholds. You can also reset or clear the Flap List. If you only want the table polled once, click the Refresh Flap List button above the Flap List Table.
