An AP can obtain an AC's IP addressthrough DNS parsing, options in the DHCP service, configured static IP address,broadcast, and multicast. During Ruijie wireless product deployment, the AP andAC IP addresses are assigned in DHCP + option 138 mode. Option 138 is used toconfigure the IP array type, and multiple AC IP addresses can be configured.
