|In this test scenario, the LANforge CT523 is used to simulate 4 virtual wireless stations that associate with a third party access point. Three traffic tests will be configured and run to demonstrate possible wireless access point tests. NOTE: This cookbook assumes that you have already created a VAP, and have an interface that is handing out DHCP addresses.
Create the virtual wireless stations.
Note: All of its virtual stations will use the same wireless AP in this example, but each station may be configured for a different AP as long as all stations on the same radio use APs on the same channel.
Go to the Port Manager
Select port wiphy0 and click Create
Select the Wifi STA button, then enter MAC, Quantity, STA ID, and SSID. Select the DHCP-IPv4 checkbox:
In this example, all 4 virtual stations will connect to the same access point
If your access point can serve DHCP, you can select the 'DHCP-IPv4' checkbox here to enable each virtual station as a DHCP client
If you choose to enter IP addresses manually, the create function will increment the last octet of the IP address for each virtual station created
Click Apply when finished
Verify that the virtual wireless stations are created
Scroll to the right to view each station's link quality and other interface details

Create Layer-3 connections between the station interfaces.
Go to the Layer-3 tab and click Create
Create a station-to-station UDP speed test:
Test 1: sta0-sta1, UDP, 30Mbps
Create a station-to-station TCP speed test:
Test 1: sta0-sta1, TCP, 1.54Mbps bi-directional traffic

Run traffic tests concurrently, and view results.
This example shows little packet loss, however being that this is traffic sent wirelessly via stations, their may be interruptions due to busy channel frequencies, if needed, adjust your Tx rate accordingly.
The Layer-3 Endpoints tab has more detail.
Select the cross-connects or endpoints and Right-Click → Dynamic Report on the L3 Endp or Layer-3 table to view a live report of the connections.
