Hello everyone,
This post is about Case Study on Managing Branch APs Through the AC at the Headquarters in the Wlan POC Test
WLAN POC Test Topology

Background requirements
The customer wants to deploy WLAN in the headquarters and branch to replace the existing wired network. The AC and AP are deployed at the headquarters and APs are deployed in the branch. APs are managed by the AC at the headquarters to manage APs on the entire network. AP7052 is connected to the AC at the headquarters through a Layer 3 network. The AP6052 is directly connected to the AC at the headquarters.
The configuration procedure is as follows
1. Ensure that the AP version matches the AC version. If the AP version does not match the AC version, the AP cannot go online. The following is the version matching table of the AC and AP.

2. Configure vlanif 100 on the AC and enable DHCP to allocate management IP addresses.
AC# Dhcp enable
AC# Vlan 100
AC# Int vlan 100
AC# Ip add 192.168.100.1 24
AC# Dhcp select int
3. Configure Vlanif 200 on SW1, enable DHCP to assign IP addresses to AP7052, and use the option43 to advertise the management IP address of the AC.
AC# Dhcp enable
AC# SW1# vlan 200
AC# Int vlan 200
AC# Ip add 192.168.200.1 24
AC# Dhcp select interface
AC# dhcp server option 43 sub-option 2 ip-address 192.168.100.1
4. The default vlan200 is configured on the interface connecting SW1 to AP7052. The interface connected to the AC bypasses the vlan100, configuration management vlanif 100.
SW1# int g0/0/1
SW1# Port link-type trunk
SW1# Port trunk pvid vlan 200
SW1# Port trunk allow vlan 200
SW1# Int g0/0/2
SW1# Port link-type trunk
SW1# Port trunk allow vlan 100 200
SW1# Vlan 100
SW1# Int vlan 100
SW1# Ip add 192.168.100.2
5. Configure static routes on the AC to the management network segment of the AP.
AC# ip route-static 192.168.200.0 255.255.255.0 192.168.100.2
6. Check the AP status on the AC. The AP can go online.
AC# dis ap all
