The maximum output data rate for interfaces can be limited with the ‘out.<intf>.limit’
parameters in the ‘qos’ interface, where <intf> is one of the following: default, eth0, mesh0,
wlan1, wlan2, wlan3, wlan4. The ‘out.default.limit’ value is applied to interfaces that have the
‘out.<intf>.limit’ parameter set to ‘inherit’. These parameters can be set via the web interface
under the “QoS” tab on the “QoS” page (see Figure 43).
The example below shows how to limit the maximum output rate of the mesh0 interface to 8
Mbps and the maximum output rates of all four wlanN interfaces to 2 Mbps each.
> use qos
qos> set out.mesh0.limit=8192
qos> set out.wlan1.limit=2048
qos> set out.wlan2.limit=2048
qos> set out.wlan3.limit=2048
qos> set out.wlan4.limit=2048
The maximum data rate for traffic that enters the EnRoute500 through a particular interface
and exits it through another interface can be limited with the ‘out.<output intf>.<input intf>.limit’
parameters in the ‘qos’ interface, where <output intf> is one of the following: default, eth0,
mesh0, wlan1, wlan2, wlan3, wlan4; and <input intf> is one of the following: default, eth0, local,
mesh0, 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. These
parameters can be set via the web interface under the “Advanced QoS” tab on the “QoS” page
(see Figure 44).
There is no standalone input rate limiting. Limiting the input rate of an interface only
makes sense in the context of the output for another interface(s). In most cases you
are concerned with mesh0 as the output interface.
The example below shows how to limit the maximum output rate of data from wlan1, wlan2,
wlan3, and wlan4 through the mesh0 interface to 2 Mbps, 1 Mbps, 512 kbps, and 256 kbps,
respectively.
> use qos
qos> set out.mesh0.wlan1.limit=2048
qos> set out.mesh0.wlan2.limit=1024
qos> set out.mesh0.wlan3.limit=512
qos> set out.mesh0.wlan4.limit=256
Data rate limits can also be imposed based on traffic type through an interface. The maximum
data rate for a certain type of traffic that enters the EnRoute500 through a particular interface
and exits it through another interface can be limited 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, mesh0, wlan1, wlan2, wlan3, wlan4; <input intf> is one of the following:
default, eth0, local, mesh0, wlan1, wlan2, wlan3, wlan4; <traffic type> is one of the following:
‘vo’, ‘vi’, ‘be’, ‘bk’ (see Table 14 for description of traffic types). These parameters can be set
via the web interface under the “Advanced QoS” tab on the “QoS” page (see Figure 44).
