When Zone Defense is enabled, the ACL resources will be reserved for Zone Defense. If the Switch does not have enough ACL resources for Zone Defense, it cannot be enabled.

When this happens, the firewall immediately and automatically contacts the Switch and issues commands to them, that result in blocking any traffic to and from the suspicious host. 556
