wlan1, wlan2, wlan3, wlan4; and <input intf> is one of the following: default, eth0, local, wlan1,
wlan2, wlan3, wlan4. The ‘out.default.default.limit’ value is applied to interfaces that have the
‘out.<output intf>.<input intf>.limit’ parameter set to ‘inherit’ or is left blank.
The example below shows how to limit the maximum output rate of data from wlan1, wlan2,
wlan3, and wlan4 through the eth0 interface to 2 Mbps, 1 Mbps, 512 kbps, and 256 kbps,
respectively.
> use qos
qos> set out.eth0.wlan1.limit=2048
qos> set out.eth0.wlan2.limit=1024
qos> set out.eth0.wlan3.limit=512
qos> set out.eth0.wlan4.limit=256
Traffic type limits can be set with the ‘out.<output intf>.<input intf>.<traffic type>.limit.’
parameters in the ‘qos’ interface, where <output intf> is one of the following: default, eth0,
wlan1, wlan2, wlan3, wlan4; <input intf> is one of the following: default, eth0, local, wlan1,
wlan2, wlan3, wlan4; <traffic type> is one of the following: ‘vo’, ‘vi’, ‘be’, ‘bk’ (see Table 13 for
description of traffic types).
The example below shows how to limit the maximum output rate of voice, video, best effort,
and background traffic from wlan1 through the eth0 interface to 256 kbps, 1 Mbps, 256 kbps,
and 256 kbps, respectively.
> use qos
qos> set out.eth0.wlan1.vo.limit=256
qos> set out.eth0.wlan1.vi.limit=1024
qos> set out.eth0.wlan1.be.limit=256
qos> set out.eth0.wlan1.bk.limit=256
Web GUI
The interface- and traffic-based Output Limit parameters can be set via the web interface
under the “QoS” and “Advanced QoS” tabs on the “QoS” page (see Figure 51 and Figure 52).
17.3 Rate Reservation
Rate reservation is used to guarantee bandwidth for certain types of traffic. Rate reservations
can be made for traffic based on:
• The traffic input and output interfaces
• The traffic type, input interface, and output interface
