Performing a Link Test

You can select Link Test to perform a short test to gauge the RF conditions between the controller and the client. If the client does not support Cisco Compatible Extensions Version 4 (CCXv4) or CCXv5, the controller will run a ping test consisting of 20 500-byte Internet Control Message Protocol (ICMP) echo packets sent to the client’s IP address. The client should reply to each of the ping packets if the wireless link is good and if the client supports ping traffic.
