If you have already configured a whitelist for a listener, Server Load Balancer can automatically add the IP addresses or CIDR blocks in the whitelist to an access control list and apply the list to the listener.

Migrate a whitelist to an access control list

To migrate a previously configured whitelist to an access control list, complete these steps:
  1. Log on to the SLB console.
  2. Select the region where the SLB instance is located, and then click the ID of the target SLB instance.
  3. Click the Listeners tab.
  4. Find the target listener, select More > Set Access Control.
  5. Click Use New Access Control Features.
  6. Enter a name of the access control list and click Create Access Control List.
  7. Click Apply to apply the list to the listener as a whitelist.
    Note If you do not apply the list to a listener, the whitelist does not take effect.
