Deleting One or More Network ACL Rules

Scenarios

You can delete network ACL rules if you no longer need them.

Deleting rules may affect how and where traffic is directed. Be careful with this operation as it may interrupt services.

To delete a network ACL rule, see Deleting a Network ACL Rule.

To delete multiple network ACL rules at a time:

If there are a small number of rules to be deleted, you can select these rules in the network ACL rule list on the console by referring to Deleting Network ACL Rules in Batches (Manually Selecting Rules on the Console).
If there are a large number of rules to be deleted, you can export the rule list to a local Excel file, only keep the rules you want to delete, and import the file to the console. The system then selects the rules to be processed based on the imported file. For details, see Deleting Network ACL Rules in Batches (Using an Excel File).
