Usage Guidelines

Usage Scenario

In AC backup scenarios, a primary AC IP address is configured. When APs attempt to go online, they preferentially associate with the primary AC and establish CAPWAP tunnels.


  • The configurations of primary-access and backup-access take effect only if both the commands are run to configure different IP addresses.
  • primary-access and backup-access cannot be configured with priority or protect-ac.
  • It is not recommended that primary-access and backup-access be configured with ac protect protect-ac or ac protect priority.
  • The configuration takes effect only after the AP is restarted.
  • The IP addresses specified by primary-access and backup-access must be configured the same as CAPWAP source IP addresses. If the CAPWAP source addresses have been translated using NAT, set the primary-access and backup-access IP addresses to the translated addresses.


# Set the primary AC IP address to

<HUAWEI> system-view
[HUAWEI] wlan 
[HUAWEI-wlan-view] ap-system-profile name sys1
[HUAWEI-wlan-ap-system-prof-sys1] primary-access ip-address
