CT314 Low Power LANforge-FIRE Traffic Generator


The CT314 is a low-power and affordable applicance with a single 10/100 Ethernet port and one Broadcome 802.11b/g/n Wireless interface. It is targeted at users who wish to have an inexpensive appliance that can be left at remote sites for network monitoring and lower speed testing. The maximum throughput is about 90Mbps bi-directional wired. Wireless throughput is steady at 38Mbps and can peak at 48Mpbs. The CT314 is based on the Raspberry PI B version 3 platform, running the Ubuntu Server OS. While it is capable of displaying a Linux desktop and LANforge GUI, the CT314 omits these items to save resources in the default install. The CT314 has no moving parts and is about the size of a deck of cards. It has HDMI, USB Keyboard, and Mouse interfaces for easy console/desktop access to the system. VoIP support is priced separately. Please communicate your preferences to your sales representative. No additional hardware or software is required, but you need a separate PC to run the LANforge GUI for easy management of the LANforge system.

Quick Start Guide

  1. Connect Ethernet port to network under test. This will also be the management network. If connecting directly to a PC, an Ethernet cross-over cable should be used. Or, connect HDMI, Keyboard, and Mouse to the chassis and manage it locally.
  2. Connect power plug to a standard US or European AC power source. Also, a micro-usb cable connected to a PC is normally enough to power the CT314.
  3. If managing remotely, install the LANforge-GUI on a separate management PC or Laptop. Windows and Linux GUIs are supported: Select the correct one from the CDROM or Candela Technologies Download page and install it.
  4. The CT314 should now boot. If DHCP is enabled on the Management network, the CT314 will automatically acquire an IP address. If DHCP is not available, the IP address will be set to 192.168.1.101 by the LANforge scripts.
  5. Start the LANforge-GUI on the management PC, and click the 'Discover' button. It should find the CT314 appliance and add the IP address to the drop-down box in the Connect widget. Press 'Connect' and you will be connected to the CT314.
  6. The CT314 is normally used in resource-only mode. In that case, the user will need to ssh or console into the system and configure the realm, resource-id, and perhaps a few other options using the /home/lanforge/lfconfig script. The GUI should not normally be connected to a resource machine, but should instead be connected to the manager machine.
  7. The CT314 has three pins available for serial console. Serial console cable is not included. Learn about connecting via serial cable.
