Hello Everyone
I just finished testing everything
The thing was working fine all the time but i noticed the fallowing things
1- it doesnt take 5 secs so the WC knows the Server is down it seems it get notice its down when a client tries to connect and then he ask the other server
2- Before when the client was trying to prove it was working he was turning off the wireless card so the WC didnt know he was down until the times out came out and for some reason when we were trying to connnect it again it keep asking the Radius1
3-When we properly disconnected it and the aruba knows the client was down we tried to connect it, it keep asking to radius1 even if it was down then like 2 mins after that it wiill ask radius2.
4-When the radius1 is down it takes 10 mins for him to take him out of the out of service as the default timer said so. So he will keep sending the request to radius2 even if radius1 is up again.
In conclusion the commnand that cjoseph told me made me realize what was happening
When we were testing it, we just disconect the wireless and tried asap instead waiting for a few... when we saw it didnt connect we just though it wasnt working....
Thanks everyone for asnwering!
