We are running Cisco WLC 220.127.116.11 as our foreign WLC and anchor WLC in the DMZ. Usually, all is fine but we observe sometimes that client cannot obtain dhcp address anymore. The DHCP server configured is the management interface of the anchor WLC and it works well except that sometimes, is stops working.
The clients are listed as associated client on the Anchor WLC but their status is DHCP REQ.
Sometimes, a reboot is required, sometimes it re-works few hours later without any intervention.
When it happens, we can see dhcp request reaching the Anchor WLC but it is like if no reply is sent.
Has anyone observed such behavior already ?
Thanks in advance,
Here is the software bug on the WLC software code that we are running!!
Please upgrade the WLC to the latest code that we have and this will resolve the issue!!
