I am testing Cisco 9800 series WLC with software version 17.3.3, 9115 AP is in local mode.
Issue: When I am using external DHCP server , also added the ip helper address command on upstream switch then all clients stuck in IP learn state.
If I use internal DHCP server then it working.
What could be the issue ?
Solved! Go to Solution.
1. Yes its there but client is getting IP when they connect with old WLC"2504"/AP but not with 9800 series.
I also created dhcp scope on switch itself for testing where WLC is connected....still not working.
2. yes i did and also using the source interface
3. no I did not try..., FYI: If I use internal DHCP server then its working but not with External.
4. Tried still not working
any other ideas ?
