What is providing DHCP.  Are you sure the leases are not used up?

Colllin is right

 

Please when it happens agains go to the cli and run

show ip dhcp statistics

You will see the free leases... if you see it on 0 thats your issue...

 

If that the issue you will want to distribute more IPs and also maybe putting a lower lease time on those...  maybe 4 hours if they are just visitors?

 

Cheers

Re: Cients couldn't get IP address for wireless Guest net.

we alredy checked the same and there is no issue with DHCP and after rebooting the guest master controller everythink works fine .

all the local controller whisch is connected to the master guest got affected due to this issue.

We do not have enough information to solve your problem.  We do not have a diagram to determine what is going on, or what is providing  dhcp and how.

Re: Cients couldn't get IP address for wireless Guest net.

Hi all,


We have Guest controller and local controler.We are connecting local controler to guest controller via Tunnel.
we have seperate DHCP pool for guest access and separte DHCP server configerade for the guest Ip pool and It is connected to Guest controller.
when clints requesting for the IP, it will get from DHCP server

 

 

Now Our issue is various local Clints which connected to differnt Local controller and not got IP address.We checked the DHCP server and other thinks realted to dhcp evrythinks works fine and rebotted the server also.It did not works well.

After rebooting the controller ,every clints got the Ip address and works fine

Re: Cients couldn't get IP address for wireless Guest net.

Which controller do you have to reboot to get this working?  Do you already have a TAC case open?

How many DHCP guest clients is that 650 serving? The internal DHCP server on the Aruba controller is only rated for 400 leases.
