Initial Setup for r720 is done. Afterwards binding with zd1200 and its network, cant able to access ssh or http.
through putty or web login. but showing online in zone director 1200
Looks like a network connectivity issues.
Try to SSH into the ZD CLI and then ping the AP IP address. Also make sure firewall is not blocking anything between your system and the AP/ZD.
If ZD is configured with management VLAN for AP communication, APs will move to configured VLAN (tagged) once configuration is pushed by the ZD, so check that part as well.
HTTP/HTTPS access will be disabled by default, once AP is managed by the ZD.
Once AP is managed by controller, web access will be disabled automatically. If required, you can re-enable it using AP CLI.
set http enable
set https enable
SSH should work so I am not sure why SSH is failing.
Are you getting any error when you try to SSH into the AP?
A next possible step can be, packet capture on switch port mirror for the connected AP and on the source system, where you are trying to SSH into the AP. Check the capture and find who is dropping the SSH.
If required, you can involve support by opening a case and they should be able to help you in troubleshooting this further.
