With a drastic increase in bandwidth absorbing network traffic (VOIP, multimedia etc.), the
importance of data prioritization is critical to effective network management.
Refer to the following fields within the QoS Mapping screen to optionally revise the existing
settings to in respect to the data traffic requirements for this WLAN.
Editing WMM settings
WLAN WMM configuration affects your upstream traffic parameters. Use “Configuring WMM” on
page 181 to configure downstream traffic parameters. Use the WMM Edit screen to modify existing
Access Category settings for the WLAN selected within the WMM screen. This could be necessary in
instances when data traffic has changed and high-priority traffic (video and voice) must be
accounted for by modifying AIFSN Transmit Ops and CW values.
To edit existing WMM Settings:
1. Select Network Setup > WLAN Setup from the main menu tree.
2. Click the WMM tab.
Access Category to
802.1p Optionally revise the 802.1p Prioritization for each access category to prioritize the
network traffic expected on this WLAN.
802.1p to Access
Category Set the access category accordingly in respect to its importance for this WLAN’s
target network traffic.
DSCP to Access
Category Set the access category accordingly in respect to its DSCP importance for this
WLAN’s target network traffic.
Differentiated Services Code Point (DSCP) is a field in an IP packet that enables
different levels of service to be assigned to network traffic. This is achieved by
marking each packet on the network with a DSCP code and appropriating to it the
corresponding level of service or priority. QoS enabled programs request a specific
service type for a traffic flow through the generic QoS (GQoS) application
programming interface (API).
