Assigning Traffic to Access Categories

WMM requires the access points to implement multiple queues for multiple priority access categories. To differentiate traffic types, the access point relies on either the application or the firewall to provide type of service (TOS) information in the IP data. SonicWall security appliances assign traffic to WMM Access Categories through two methods:

• Specifying Firewall Services and Access Rules

• VLAN Tagging

Specifying Firewall Services and Access Rules

Services using a certain port can be prioritized and put into a proper transmit queue. For example, UDP traffic sending to port 2427 can be regarded as a video stream. Add a custom service on the OBJECT | Services > Service Objects page. Refer to SonicOS Policies for more information.

At least one access rule should be added on the POLICY | Rules and Policies > Access Rules page for the new service. For example, when such a service happens from a station on the LAN zone to a wireless client on the WLAN zone, an access rule can be configured in the Adding Rule window. In the Traffic Shaping tab of the Adding Rule window, an explicit DSCP value is defined.

Later, when packets are sent to the access point through the firewall using UDP protocol with destination port 2427, their TOS fields are set according to the QoS setting in the access rule.

VLAN Tagging

Prioritization is possible in VLAN over virtual access point because the SonicWave, SonicPoint N and ACs allow a virtual access point to be configured to connect with a VLAN by using same VLAN ID. You can set priority for VLAN traffic through a firewall access rule.

The firewall access rule is similar to setting priority for a UDP service destined to a port such as 2427, but is configured with a VLAN (VLAN over VAP) interface, such as WLAN Subnets, as the Source and Destination is a WLAN-to-WLAN rule. Refer to SonicOS Policies for more information.
