different network segments. The DHCP function must be enabled on VLANIF interfaces
instead of the loopback interfaces to allocate IP addresses to APs.
Enable the dual-link backup function on AC1 and AC2 and set a priority for each AC.
Run the following commands:
[AC6605_AC1] wlan
[AC6605_AC1-wlan-view] wlan ac protect enable protect-ac 30.30.30.2 priority 0
[AC6605_AC2] wlan
[AC6605_AC2-wlan-view] wlan ac protect enable protect-ac 30.30.30.1 priority 7
In the preceding commands, protect-ac specifies the IP address of the standby AC. Set
this parameter to the other AC's IP address on each AC. The active AC must have a
higher priority than the standby AC. The value 0 indicates the highest priority, and the
value 7 indicates the lowest priority. A smaller value indicates a higher priority. Run the
display wlan ac protect command to check the AC priorities.
[AC6605_AC1] display wlan ac protect
