Enabling or Disabling a Network ACL

Scenarios

After a network ACL is created, it is enabled by default. You can disable it as required.
  • If a network ACL is disabled, custom rules become invalid, but the default rules are still applied. As a result, all traffic to and from the associated subnets is denied. If a network ACL has a subnet associated, disabling it will interrupt the network traffic to and from the subnet.
  • If a network ACL is enabled, both custom and default rules are applied. If a network ACL has a subnet associated and has only default rules, enabling it will interrupt the network traffic to and from the subnet.

Procedure

  1. Go to the network ACL list page.
  2. In the network ACL list, enable or disable the target network ACL.
