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 WLAN.
•
The
required
option requires client devices to use WMM; devices that do not support WMM cannot
join the WLAN.
Note
Do not enable WMM mode if Cisco 7920 phones are used on your network.
