Configuring QoS Enhanced BSS (QBSS)
You can enable QBSS in these two modes:
• Wireless Multimedia (WMM) mode, which supports devices that meet the 802.11E QBSS standard
• 7920 support mode, which supports Cisco 7920 IP telephones on your 802.11b/g network
QBSS is disabled by default.
Enabling WMM Mode
Enter this command to enable WMM mode:
config wlan wmm {disabled | allowed | required} wlan-id
• The allowed option allows client devices to use WMM on the wireless LAN.
• The required option requires client devices to use WMM; devices that do not support WMM cannot
join the wireless LAN.
Note Do not enable WMM mode if Cisco 7920 phones are used on your network.
