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.
  • Set community string: The community string in order to set to the device. The default value is private.

Usage

General

This page provides an overview of the most important parameters of the device, divided in two sections.

The System Information section contains the following parameters:

  • Model Number
  • Hardware Revision: The modem hardware revision, in the format is "xx.y", where xx indicates the main (bottom) card, and y indicates the top (modem) card.
  • Software Revision
  • Serial Number
  • System Up Time: The time that the device has been operating.

The Device Overall Status section contains the following parameters:

  • Unit Alarm: Modem unit faults.
  • Tx Traffic Alarm: Modem TX traffic faults.
  • Rx Traffic Alarm: Modem RX traffic faults.
  • Offline Unit Status: Provides access to the fault status information of the offline modem. This is the only way to interrogate the status of an offline modem at the distant end of a link.
  • Unit Test Mode: Allows you to select the type of unit test mode.
  • EDMAC Framing Mode
  • Temperature: The internal temperature of the modem.
  • Toggle Polling Speed: Allows you to toggle between Normal Polling and Fast Polling of the parameters of the device.

Admin - Access / SNMP

On this page, you can configure the host's IP addresses, as required to enable communication with the CDM-625 web server interface and to set administration information for the CDM-625 Simple Network Management Protocol (SNMP) feature.

These options are only available when the device is working in Local mode (see "Config - Utilities" section below).

  • Host Access List:

    • Access List: Allows you to grant access via HTTP and SNMP to a defined list of client machines.
    • Access List Overview: Allows you to define which remote clients can connect when Access List is Enabled. Each entry allows you to specify an IP Address and a Subnet Mask to define a unique class of machines that are allowed access.

  • SNMP:

    • Trap IP 1 / Trap IP 2: Allow you to assign up to two SNMP trap IP addresses.
    • Trap Version: Allows you to set the trap version to SNMPv1 or SNMPv2 using the drop-down list.
    • Trap Community String: Allows you to assign the SNMP trap community string. The community string must consist of a minimum of 0 to a maximum of 20 alphanumeric characters.

Admin - FAST

The CDM-625 has a number of optional features that can be activated after the unit's purchase. Fully Accessible System Topology (FAST) Access Codes are register-specific, unique authorization codes that can be purchased from Comtech EF Data.

  • Equipment ID: This read-only section displays the operational status for a number of FAST-enabled features.
  • Hardware: The list displays the installed and presently operational FAST-enabled features as well as the non-installed FAST-enabled features that are available for purchase and activation from Comtech EF Data.

Config - Modem

Use this page to configure modem operating (Tx/Rx) parameters:

  • Tx/Rx Interfaces and Framing: The Tx/Rx Interface Types and Framing Modes have higher priority over the other parameters. They should be configured before other parameters are set.
  • Tx/Rx operating parameters: Remaining parameters for configuration.
  • Carrier-in-Carrier (CnC) parameters: Click the CnC page button to access CnC configurable parameters.
  • ACM parameters: Click the ACM page button to access ACM configurable parameters.

Config - LAN - IP

Use this page to configure LAN IP-related parameters. Some options are only available when the device is working in Local mode (see "Config - Utilities" section below).

The Network Configuration section consists of the following parameters:

  • IP Gateway: The IP address of the default gateway. Applicable only if Working Mode is set to Managed Switch.
  • Traffic/Mgmt IP Address (and subnet mask): Can be used to configure the modem's IP addresses.
  • MAC Address: The MAC address of the Ethernet port. This parameter is read-only and cannot be changed.
  • MAC Learning: Applicable only if Working Mode is set to Managed Switch. Use the drop-down menu to set MAC Learning to On or Off.
  • WAN Buffer Length: Enter a value between 20 ms and 400 ms, in 20 ms increments.
  • L2 QoS (Layer 2 QoS): Use the drop-down menu to set this feature to Off, VLAN Only, Port Only, or VLAN & Port.

  • Dedicated Management Port: This feature is available if Working Modes is set to Managed Switch, but it is unavailable when VLAN Mode is Enabled or when the optional IP Packet Processor is Enabled. Use the drop-down menu to select Port 1, Port 2, Port 3 or Port 4 as the dedicated management port. If Port 1 (2, 3, 4) - Local Only is selected, management is restricted to LAN only. Note that when the optional IP Packet Processor is Enabled, the drop-down menu displays Disabled. When VLAN Mode is Enabled, the drop-down menu displays all previously described options, but it will not be possible to select any of them.
  • 2048 Ethernet Frame Size: This feature is only supported on modems with hardware revision 2.X or higher. Set this feature to Disabled or Enabled.
  • Working Mode: Use the drop-down menu to select one of the following working modes: Managed Switch, Router Point-to-Point, Router Multipoint Hub or Router Multipoint Remote.

In the Per Port Configuration Table, you can set parameters for each port (Port 1 to Port 4):

  • Port Speed: Use the drop-down menu to select the speed for each selected port: Auto, 100 Full-Duplex, 100 Half-Duplex, 10 Full-Duplex or 10 Half-Duplex.

  • Native Mode: Set Native Mode for the port to Disabled or Enabled.
  • PVID: When Native Mode is Enabled, a PVID (Native VLAN ID) may be assigned to the selected port using a value range of 0001-4095.
  • Priority: Use the drop-down menu to set the operational priority of the selected port, in the order of preference (from 1 to 4).
  • Actual Negotiated Port Speed: This is the status of the current actual operating speed and duplex. If the port is not connected, "Link Down" is displayed.

VLAN Mode: This mode is supported if Working Mode is set to Managed Switch, with or without the optional IP Packet Processor enabled. The VLAN Mode section contains the following parameters:

  • VLAN Mode: Set the mode to Disabled or Enabled.
  • Management VLAN ID: A management VLAN ID can be assigned to the selected port using a value range of 0001-4095.

Below this, you can find the VLAN Table, which contains the following parameters:

  • VLAN ID: This parameter is read-only and reflects the ID value assigned in de PVID column of the Per Port Configuration Table (i.e., any ID has a value range of 0001-4095).
  • Port 1 through Port 4: Use the drop-down menu to set the port to Untagged, Tagged or Filtered.
  • VLAN Row Status: You can use the button to Delete the VLAN ID.
  • Create VLAN: Allows you to create a new VLAN ID.
