Wireless terminal cannot obtain IP address

AC-Core SW-AP

After the AP is online, it is found that the AP can get the address, but the terminal cannot get the address. The vlan of the terminal is configured on the AP, and this vlan-interface can get the address normally.

1. Configuring the terminal vlan on the ap can get the address, which means the dhcp service is fine.

2.According to the feedback from the field engineer, the previous wireless service was normal, and only the core switch was replaced. It means that there is no problem with the configuration.

3. Confirm that the site is configured for user isolation, but in the MAP file, the corresponding configuration has been deleted.

4. Check the AP configuration and find that the corresponding configuration does not match the map file

1. delete or modify the configuration of user isolation on the AP to change the corresponding MAC to the new switch mac after replacement

2. Get the AP offline and online again to reacquire the MAP file.
