AP 7161 mesh option


We would like to know how to conifgure our Motorola 7161 APs to be able to join each other in a mesh after it has powered up. Currently, if an AP is powered up prior to being in range then it selects a channel and will only join the other AP if it happens to be in that same channel. To overcome this issue wehave setup static channels. That casues its own issues, and we require to have dynamic channel conifguratrion. Is there a way to overcome this restriction?

Thank you
