Chapter 17: Quality of Service (QoS) Configuration
TR0190 Rev. A1 113
The maximum output data rate for interfaces can be limited with the Output Limit parameters
for each client access interface. The default output limit value is applied to interfaces that have
the Output Limit parameter set to ‘inherit’.
Figure 53. Quality of Service rate limit control points
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 EL-500 through a particular interface and
exits it through another interface can be limited.
There is no standalone input rate limiting. Limiting the input rate of an interface on
the EL-500 only makes sense in the context of the output for another interface(s). In
most cases you are concerned with eth0 as the output interface.
CLI
The example below shows how to limit the maximum output rate of the eth0 interface to 8
Mbps and the maximum output rates of all four wlanN interfaces to 2 Mbps each.
> use qos
qos> set out.eth0.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 EL-500 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,
