When any access control rule becomes unnecessary or obsolete, remove it.
To delete a role-based access control rule:
Choose Device Settings > Security > Role Based Access Control. The Configure Role Based Access Control Settings dialog appears.
To delete the IPv4 firewall rules, click the IPv4 tab. To delete the IPv6 firewall rules, click the IPv6 tab.
Ensure the "Enable Role Based Access Control for IPv4" checkbox is selected on the IPv4 tab, or the "Enable Role Based Access Control for IPv6" checkbox is selected on the IPv6 tab.
Select the rule to be deleted in the rules list. To make multiple selections, press Ctrl+click or Shift+click to highlight multiple ones.
Click Delete.
A message appears, prompting you to confirm the operation. Click Yes to confirm the deletion.
