Client DHCP Issues

Hi, All

 

Just looking to see if anyone else has run across the same issue. One of our customers have been having issues where random wireless clients after connecting to the employee wireless and getting Authentications can not brows local or internet resources.

After looking in the Aruba controller they show the client as have an old IP address and basically sandboxes them. They can reboot, re-logon with no change. Because they still get the same new IP address from the external DHCP server. You have to login to the Aruba controller and clear the user on the controller before they can reconnect and then they work as normal. This happens three to five times a week in a large campus environment.

 

Any help would be great.

Re: Client DHCP Issues

Hi Wizard,

 

Are you using role derivation in this install? If so, try moving the following rule:

 

any any svc-dhcp  permit 

 

to the top of any derived roles. Previously, a customer of mine relied on the "any any any permit" rule at the end of their derived rules for DHCP and it caused something similar to what you may be seeing. The change with the svc-dhcp rule improved DHCP across the board.

Re: Client DHCP Issues

A. Upgrade to the latest AOS (6.1.3.8 for example)

A2. Save config & reboot

B. Run this command in the cli: 

aaa user delete all
C. make sure u didnt change any configuration in the aaa-advanced tab. (Logon user lifetime|User idle timeout|Auth Server dead time)
D. what is the lease time in your DHCP server?

Hi, kdisc98

 

Upgrade is very difficult to go through with this customer it is a large campus and requires going through change controller. So if it not a guarantied fix I will wait to look deeper. This has been an open issue for a few months so it is a sore subject for them.

We did do an upgrade to 6.1.3.5 with no change.

 

Thanks,
