When planning your mappings, make sure that any immediate switch or router does not have conflicting
802.1p or DSCP configurations/mappings. If this occurs, your traffic may not be prioritized correctly.
To view the mapping settings, use the following command:
(host)#show wlan ssid-profile <profile>
In the WebUI
To map WMM AC with DSCP:
1. Navigate to the Configuration > Wireless > AP Configuration page.
2. Select either the AP Group or AP Specific tab. Click Edit for the AP group or AP name.
3. In the Profiles list, select Wireless LAN, then Virtual AP, then the applicable virtual AP profile. Select the
SSID profile.
4. In the Profile Details, select the Advanced tab.
5. Scroll down to the Wireless Multimedia (WMM) option. Select this option.
6. Modify the DSCP mapping settings, as needed:
n DSCP mapping for WMM voice AC—DSCP used to map voice traffic
n DSCP mapping for WMM video ACDSCP used to map video traffic
n DSCP mapping for WMM best-effort AC—DSCP used to map best-effort traffic
n DSCP mapping for WMM background AC—DSCP used to map background traffic
7. Click Apply.
In the CLI
To map WMM AC with DSCP:
(host)(config)#wlan ssid-profile <profile>
wmm-be-dscp <best-effort>
wmm-bk-dscp <background>
wmm-vi-dscp <video>
wmm-vo-dscp <voice>
The following enhancements have been made to the WMM-DSCP mapping functionality:
l When a controller is upgraded to the 6.2 version from an older version, the default and the user configured
WMM-DSCP mappings in the existing SSID profiles are retained.
l Default mappings are not there for a newly created SSID profile and for a factory default controller a
running 6.2 image.
l If the mapping has no value, the original DSCP for upstream traffic is retained.
l The maximum number of values that can be configured for WMM-DSCP is 8.
l For the upstream traffic, if the mapping exists and incoming DSCP value matches one of the mapped
values, then the DSCP value is retained.
l For the upstream traffic, if the mapping exists and incoming DSCP value does not match any of the mapped
values, then the DSCP value is overwritten with the first value in the WMM- DSCP list
l For Wireless to Wireless Traffic: If the AC of the incoming packet has no mapping and the incoming DSCP
value is mapped to a different AC, then the DSCP value is retained and WMM priority is changed to the
corresponding AC where incoming DSCP is mapped.
Configuring DSCP Priorities
You can configure DSCP priorities for WMM packets in the following ways:
l configure the DSCP mappings in the SSID profile
l set a ToS value in the ACL
