DHCP issues in WLC

Hi all ,

We are using 5508 WLC with 7.4.100.0 version and AP's are 3600 .we have configured internal DHCP lease for the clients . We have one SSID with  802.1x auth WPA2/AES encryption .

The problem is some 35 of our laptop is not getting IP address  oftenly from WLC .Remainig clients are getting IP with no problem .Any bug on this?

Thanks,

Regards,

TS.

Re: DHCP issues in WLC

Hi Vijay,

You are running on the very first release of 7.4 code & that came with lots of bugs. So it is highly recommended to upgrade your WLC software to either 7.4.110.0(7.4MR1) or 7.4.111.x (7.4MR2 pre-release) available through TAC

I am sure your issue will get fixed by one of this upgrade.

Also make sure your WLC FUS also get upgraded to 1.7.0.0 if it is not already in that version.
