Changing QoS
Settings You can change the settings of the following QoS options:
„
QoS mode
„
U-APSD support
„
CAC state and maximum number of sessions
„
Broadcast control
„
Static CoS state and CoS value
„
DSCP-CoS mappings
„
Using client DSCP value to classify QoS level of IP packets
The QoS mode is configurable on a radio-profile basis. CAC and static
CoS are configurable on a service-profile basis. DSCP-CoS mapping is
configurable on a global switch basis.
Changing the QoS
Mode
The default QoS mode is WMM. To change the QoS mode on a radio
profile, use the following command:
set radio-profile name qos-mode {svp | wmm}
For example, the following command changes the QoS mode for radio
profile rp1 to SVP:
WX1200# set radio-profile rp1 qos-mode svp
success: change accepted.
SVP configuration requires ACLs to set CoS, in addition to the SVP QoS
mode. (For information, see “Enabling SVP Optimization for SpectraLink
Phones” on page 404.)
Enabling U-APSD
Support
U-APSD support is disabled by default. To enable it on a radio profile, use
the following command:
set radio-profile name wmm-powersave {enable | disable}
For example, the following command enables U-APSD on radio profile
rp1:
WX# set radio-profile rp1 wmm-powersave enable
success: change accepted.
