WLAN Controller on remote WAN?????

[pepsico_anz1]

Hi Guys,

In the event of a WLAN controller, can the APs assosiate to a controller a thousand miles away?

The backup controller would be located in the DC where 100% of traffic is destined anyway so bandwidth is not of major concern.

Thanks

Yes....BUT the maximum round trip time allowed is 100ms between AP and WLC. Also it may be best to set the AP's in H-REAP also

HTH

thanks!

round time is ok, for all but one site, 4000+km away, 65ms with no traffic....often much higher

ill read up on h-reap, cheers

no problem - glad to help

if you read this:-

http://www.cisco.com/en/US/docs/wireless/controller/4.0/configuration/guide/c40hreap.html

it will give you alot of good information - but this is for WLC ver 4.0 - in 4.1/4.2 & 5.0 you get more functionality for H-REAP!
