Allied Telesis x900-48 series manual AlliedWare OS How To Note QoS configuration

1. Setting the egress rate

Example 1-4: Setting the maximum bandwidth limit for each IP subnet

This example is very similar to example 1-3, except that it is assumed that a whole subnet is attached to each port, not just a single device on each port.

Port 24

Internet connection

Users connected to the switch downloading files from the Internet

(192.168.1.0/24 - 192.168.23.0/24)

create class=1	ipda=192.168.1.0/24
create class=2	ipda=192.168.2.0/24
create class=3	ipda=192.168.3.0/24
...
create qos flow=1
add qos flow=1	class=1
create qos traf=1
add qos traf=1	flow=1
set qos traf=1	maxbandw=256kbps maxburst=5kbyte dropbw=yes
create qos flow=2
add qos flow=2	class=2
create qos traf=2
add qos traf=2	flow=2
set qos traf=2	maxbandw=256kbps maxburst=5kbyte dropbw=yes
create qos flow=3
add qos flow=3	class=3
create qos traf=3
add qos traf=3	flow=3
set qos traf=3	maxbandw=256kbps maxburst=5kbyte dropbw=yes
...
create qos poli=1
add qos poli=1	traff=1-23

set qos port=24 poli=1

This set of commands will set the total egress limit (download traffic) for each subnet to 256kbps. The granularity is around 1kbps.
