The site is forwarded locally, and AC acts as DHCP to assign addresses to APs and terminals. after APs come online, it is found that APs can get addresses, but terminals cannot get addresses. The vlan 3 port of the terminal is configured on the AP, and the address can be acquired normally.

1. The configuration terminal vlan on the ap can get the address, indicating that its own wired and dhcp services are not a problem. 

2. According to the feedback of the field engineer, the previous wireless service is normal, only the core switch to do the cut. This means that the configuration is not a problem. 

3. To confirm the site configuration of user isolation, but the MAP file, the corresponding configuration has been deleted.

4. Check the AP configuration, found that the corresponding configuration and map file is not consistent

1. Delete or modify the configuration of user isolation on the AP, and change the corresponding MAC to the new switch mac after cutover 2. Let the AP offline again online, re-acquire the MAP file.
