The CT502 is an excellent choice for testing firewalls, routers and other devices that pay attention to network flows. The CT502 uses the MAC-VLAN feature in the Candela Linux kernel to emulate up to 250 virtual interfaces using a single physical ethernet interface. Each of the virtual interfaces has it's own IP address, IP port space, MAC address and routing table. This allows one to configure all of the virtual interfaces on the same subnet, or different subnets, depending on the testing requirements. When used with something like VoIP, it allows all of the VOIP calls to use the standard IP ports (with one call per virtual interface). The CT502 1U rackmount chassis fits into a standard rack and is only 14 inches deep. It supports standard VGA, Keyboard, and Mouse interfaces for easy console/desktop access to the system. The rackmount chassis is relatively noisy, so it is better for a data center deployment than a desktop environment. Other form factors better suited for traveling or desktop use are also available at similar prices and performance. VoIP support and the Armageddon feature are priced separately. Please communicate your preferences to your sales representative. No additional hardware or software is required, but you may wish to manage the system using the LANforge-GUI on a separate machine.

1. Connect Management ethernet port to Management network or management PC. If connecting directly to a PC, an ethernet cross-over cable should be used. Or, connect VGA, Keyboard, and Mouse to the chassis and manage it locally.
2. Connect one traffic generating port to the downstream side of the device under test. This usually is considered the 'client' side of the network and will host most of the virtual interfaces.
3. Connect second traffic generating port to the upstream side of the device under test. Virtual interfaces may also be added here in order to emulate multiple servers.
4. Connect power plug to a standard US or European AC power source.
5. 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.
6. The CT502 should now boot. If DHCP is enabled on the Management network, the CT502 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.
7. Start the LANforge-GUI on the management PC, or the CT502 server if managing locally, and click the 'Discover' button. It should find the CT502 appliance and add the IP address to the drop-down box in the Connect widget. Press 'Connect' and you will be connected to the CT502.
8. Select the Layer 3, VOIP/RTP, Layer 4 and other LANforge-FIRE related tabs in the GUI to see existing traffic connections and to modify them or add new ones. You can also view a real-time report of the test with the 'Display' button for some traffic types. Any modifications take place immediately after you click 'Submit'.

• Uses publicly available Linux and Windows networking stack for increased standards compliance.
• Utilizes libcurl for FTP, HTTP and HTTPS (SSL) protocols.
• Supports file system test endpoints (NFS, SMB, and iSCSI file systems, too!). NFS file system mounts can use the virtual interface feature for advanced testing of NFS file server applications.
• Supports custom and command-line programs, like telnet, SMTP, and ping.
• Comprehensive traffic reports include: Packet Transmit rate, Packet Receive rate, Packet Receive Drop %, Transmit Bytes, Receive Bytes, Latency, various ethernet driver level counters, and much more.
• Supports generation of reports that are ready to be imported into your favorite spread-sheet.
• Allows packet sniffing and network protocol decoding with the integrated Wireshark protocol sniffer.
• GUI runs as Java application on Linux, Solaris and Microsoft Operating Systems (among others).
• GUI can run remotely, even over low-bandwidth links to accommodate the needs of the users.
• Central management application can manage multiple units, tests, and testers simultaneously.
• Supports scriptable command line interface (telnet) which can be used to automate test scenarios. Perl libraries and example scripts are also provided!
• Comprehensive management information detailing all aspects of the LANforge system including processor statistics, test cases, and ethernet port statistics.
• Automatic discovery of LANforge data generators simplifies configuration of LANforge test equipment.
• LANforge traffic generation/management software is supported on Red Hat Linux and MS Windows.
