Welcome to Cisco Support Community. We would love to have your feedback.
For an introduction to the new site, click here. If you'd prefer to explore, try our test area to get started. And see here for current known issues.
We installed a Cisco WLC 5508 with AIR OS 22.214.171.124 into our DMZ as termination point for our OEAP 600 series and
also for our Flexconnect APs. After we implemented this solution then from time to time some HREAP/Flex APs lost the
connection and re jonide 2 -3 hours later or 2-3 days later and we don´t know why.
We checked the logfile from the WLC and APs and saw also everytimes connection requests to the NAT IP from our WLC.
After we add following command on the Remote sites router
"ip route WLC IP Null0 name"
then it seems to be the problem is solved .
The thing for me is I never heard of it to add this command in context with the Cisco OEAP solution .
Could this be a software bug in the Cisco AIR OS 7.4.110 ?
Typically you also need to issue this on the WLC:config network ap-discovery nat-ip-only disableSent from Cisco Technical Support iPhone App
Thanks for the information but I added this command from beginning. For me it seems to be this is the same issues as descibed in following thread:
