i have a controller that has mutliple dhcp scopes and should in theory give out close to a thousand plus addresses. But i have seen wireless users not getting addresses once the controller has leased about 490 ip adds. anyone see anything like this or know of any known bugs? my controller is on 7.XX version.
If you are on 126.96.36.199, then you could definitely be hitting: CSCth68708 and is resolved in 188.8.131.52. If you are on 184.108.40.206 I would highly suggest moving on up to the latest release 220.127.116.11, if your infrastructure allows.
If the version is not 18.104.22.168, how have you verified that the WLC is not "handing out" addresses other than the clients not getting one? Do you have a capture/debug?
I second David about the bug issue.
This was very common for those on 22.214.171.124 or 126.96.36.199.
My version is 188.8.131.52. I do not have a capture (will be doing so), but when I look at the controller stats for dhcp leases, I have never seen it go above 500 leases, although I have several scopes (multiple ssids), and I know we should be giving out more leases. My lease time-outs for diff. scopes are set for 30 mins, 3 hours , 2 hours etc.
