Creating Services, QoS Profiles, and Bandwidth Profiles
When you create inbound and outbound firewall rules, you use firewall objects such as services,
QoS profiles, bandwidth profiles, and schedules to narrow down the firewall rules:

information about adding services, see “Adding Customized Services” on page 4-19.
• QoS profiles. A quality of service (QoS) profile defines the relative priority of an IP packet
