CISCO CMTS
The CISCO CMTS is an SNMP connector. It is used to poll data from the CMTS, which manages all data from a usually large number of connected CPEs.

Configuration
Connections
SNMP Main Connection
This connector uses a Simple Network Management Protocol (SNMP) 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.
Usage
General
This page contains all general device information, such as the Uptime, Name, Contact, etc. It also includes Cable Modems summary information and Upstream/Downstream capacity summary information.
In addition, you can normalize some parameters and enable automatic cleaning for the tables. However, note that this is not available from version 3.0.0.1 onwards, and should then be performed by template instead.
The page contains the following page buttons:
- Advanced: Used to manage the Capacity Factor.
- Power Supplies, Processors, Physical Info, Temperature, Fans: Display information related to each of these topics. From version 3.0.0.2 onwards, each of the polling tables can be enabled or disabled. By default, these tables are disabled. They can be managed on the Polling Control page.
Configuration - Upstream Channels
On this page, a table is displayed where you can configure the upstream channels of the CMTS. From version 3.0.0.2 onwards, this table does not display content by default. You can enable this functionality on the Polling Control page.
Configuration - Downstream Channels
On this page, a table is displayed where you can configure the downstream channels of the CMTS. From version 3.0.0.2 onwards, this table does not display content by default. You can enable this functionality on the Polling Control page.
Measurement - Upstream Channels
This page contains a table with the current values of the upstream channels of the CMTS. From version 3.0.0.2 onwards, this table does not display content by default. You can enable this functionality on the Polling Control page.
In addition, some alarm settings can be configured.
Measurement - Downstream Channels
This page contains a table with the current values of the downstream channels of the CMTS. From version 3.0.0.2 onwards, this table does not display content by default. You can enable this functionality on the Polling Control page.
In addition, some alarm settings can be configured.
Measurement - Gigabit Interface
This page contains a table with the current values of the Gigabit Interface of the CMTS. From version 3.0.0.2 onwards, this table does not display content by default. You can enable this functionality on the Polling Control page.
In addition, you can configure the Sliding Window Size.
Measurement - Wideband Interfaces
This page contains a table with the current values of the wideband interfaces of the CMTS. From version 3.0.0.2 onwards, this table does not display content by default. You can enable this functionality on the Polling Control page.
Measurement - MAC Layer
This page contains a table with the current values of the MAC Layer of the CMTS. From version 3.0.0.2 onwards, this table does not display content by default. You can enable this functionality on the Polling Control page.
CM Downstream
This page contains a summary of the CM-related information from the table Measurement - Downstream, containing only initialized records.
CM Upstream
This page contains a summary of the CM-related information from the table Measurement - Upstream, containing only initialized records.
Signal Quality
From version 3.0.0.2 onwards, detailed information related to signal quality is displayed on this page. However, SNMP polling is by default disabled. You can enable this functionality on the Polling Control page.
Flaplist
This page contains a table with the current values of the CPEs.
Interfaces
This page displays the interfaces contained in the CMTS, as well as page buttons that display additional information related to interfaces, i.e., Extended Information, Interface Errors, Interface Utilization, Cable Modems per Bounding Group and Cable Modems per MAC Domain.
From version 3.0.0.2 onwards, SNMP polling is not enabled by default. It can be managed on the Polling Control page. However, the Interface table is always enabled.
Offload
This page contains settings concerning the Offload of the CMTS.
CPE Manager InterOP
On this page, you can enable the functionality to establish interoperation with the Generic DOCSIS Cable Modem Collector. An element ID in the format DMAID/ElementID must be provided for this.
Topology
On this page, you can configure the export of CPE topology information to CSV files. This process creates a set of provisioning CSV files in the indicated directory and is executed by a process button.
The Topology Provisioning Schedule table allows you to configure automatic topology file generation by adding entries with the day and time when a topology file should be generated.
If you enable CM Differences Only, the cable modems relationship is only created when there are changes or differences between readings.
Ping Function
This page contains settings related to the Ping Function of the CMTS. You can also create a Provisioning File here.
Polling Control
On this page, you can manage SNMP polling and determine which table content is displayed. Most of the features of this connector are disabled by default, in order to reduce the load on the CMTS. When a configuration or measurement table is enabled, any polling tables and/or display tables that are required for its functionality will be enabled.
Bitrate calculation mode can be calculated using the values indicated by the utilization table, based on the available capacity configured in the interface. Alternatively, the regular method of octets calculation can be used.
Interface capacity can be set for full bandwidth value or without the known size of header data in order to interpret saturation values for downstream type interfaces. This configuration can be managed on this page.
Finally, you can also force an update of the device interfaces on this page.
Detailed Interface Info page
On this page, the interface info is displayed.
Click XMPL RPC to retrieve data that is not available on the CISCO device itself, e.g., to retrieve the IF Speed from a server. The data will be retrieved via calls to a customized platform.
Via Measurement Configuration, you can configure a more detailed Interface.
More detailed information about the incoming and outgoing information can be found on the Detailed Information Info - Rx and Detailed Information Info - Tx pages.
