CT525-928-2ac-4n LANforge WiFIRE 802.11a/b/g/n/AC 6-radio WiFi Traffic Generator supporting 928 Virtual STA Interfaces

The CT525-928-2ac-4n wireless traffic generator is an excellent choice for testing Access Points and other WiFi networks. The ath9k (a/b/g/n) chipset NICs can support up to 200 stations per radio. The ath10k (a/b/g/n/ac) chipset NICs can support up to 64 stations per radio. __AX_AMT_PER_RAD_TXT__ Each of the Virtual Stations has its own IP address, IP port space, MAC address and routing table. The Virtual Stations can be assigned to communicate to a particular Access Point, use a particular SSID, and Open or WPA/WPA2 authentication assigned. More advanced 802.1X authentication is also included. Each radio can be configured independently of the other. Transmit power and channel/frequency is configured on a per-radio basis. Most other settings are configurable per virtual station.

There are two a/b/g/n/AC and four a/b/g/n WiFi radios per CT525-928-2ac-4n and multiple LANforge systems can be clustered together for even more realistic radio interference patterns and increased traffic generation capability.

All virtual stations on the same radio must be on the same frequency, but as long as the protocol supports that frequency, the multiple protocols can be used concurrently. For instance, if the radio is configured for a 2.4Ghz channel, the stations can be /b, /g, /n, or /ax. If the radio is on a 5Ghz channel, the stations can be /a, /n, ac, or ax. The bandwidth can be configured for all protocols.

The Virtual Stations may be configured with 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 CT525-928-2ac-4n is a 2U rackmount system. It has 18 antennas. It will fit into a standard rackmount cabinet. No additional hardware or software is required, but it is suggested that you manage the system using the LANforge GUI on a separate machine. The CT525-928-2ac-4n can also be managed over a serial console in text mode or through a directly connected monitor, mouse and keyboard.

Performance exceeds 900Mbps per 802.11AC radio: Open   |   WPA2 |   TCP-DL-30sta |   UDP-Netgear-64sta |   TCP-Netgear-64sta |   UDP-LANforge-AP-64sta |   TCP-LANforge-AP-64sta |   Hunt-Open |   Hunt-WPA2

Example Network Diagram

Quick Start Guide

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.
2. Connect eth1 wired Ethernet interface to wired Ethernet interface on the AP or network under test. This usually is considered the 'server' side of the network.
3. The Client side of the network will be the Virtual Stations configured on the CT525-928-2ac-4n WiFi NIC(s).
4. Connect power to standard US or European AC power source. If using external battery pack, then connect to that instead. Click button to power on the unit.
5. The CT525-928-2ac-4n should now boot. If DHCP is enabled on the Management network, the CT525-928-2ac-4n will automatically acquire an IP address. If DHCP is not available, the IP address will be set to 192.168.1.101.
6. Install the LANforge-GUI on a separate management PC or Laptop, or use VNC or remote-desktop programs to access the LANforge system directly. Windows, MAC-OS and Linux GUIs are supported: Select the correct one from the web page served from the LANforge system and install it.
7. Start the LANforge-GUI on the management PC and click the 'Discover' button. It should find the CT525-928-2ac-4n appliance and add the IP address to the drop-down box in the Connect widget. Press 'Connect' and you will be connected to the CT525-928-2ac-4n.
8. Select the Port Mgr tab in the GUI. Double-click on the device called 'wiphy0'. This is the Radio device, and should be configured for the correct, channel, country-code, etc. Next, select one or more of the Virtual Station interfaces and click 'Modify'. Enter the correct IP address information, SSID and WPA/WPA2 password (if Enabled). After applying these changes, the Virtual Station interface should associate with the AP and be ready to send traffic. You may create up to 928 Virtual Station interfaces per CT525-928-2ac-4n with the 'Create' button.
9. Once the interfaces are configured correctly, you can click on the Layer 3, VOIP/RTP and other LANforge-FIRE related GUI tabs and configure/modify/start/stop particular traffic patterns that utilize the virtual stations and wired Ethernet interface. In most cases, you will want one of the FIRE endpoints to be on the wired interface and the other to be on the WiFi Virtual Station interface. It is also valid to generate traffic between two Virtual Station interfaces. The GUI Chamber View window provides some automated test suites. Contact support if you have suggestions for improvements.
10. Any GUI modifications take place immediately after you click 'Submit' or 'OK'.
