Setting the egress rate Example 1 - 1 : Setting the egress limit of a switch port Command: set switch port=24 egresslimit=640 This command will set the egress limit of port 24 to 640kbps. The granularity is 640kbp...

Page 3 | AlliedWare™ OS How To Note: QoS configuration 1 . Setting the egress rate Example 1 -2: setting the maximum bandwidth limit per ingress port Ingress rate limiting cannot be configured on the port per se, but is achieved by creating a QoS policy with a bandwidth limited traffic class, and ap...

Page 4 | AlliedWare™ OS How To Note: QoS configuration 1 . Setting the egress rate Example 1 -3: Setting the maximum bandwidth limit for each user In example 1 - 1 , we configured an egress rate on ports. But the granularity of that bandwidth limiting was multiples of 640kbps. To achieve a finer-gra...

Page 14 | AlliedWare™ OS How To Note: QoS configuration Full QoS scenario 1 : tiered services for a single customer Bronze traffic is also allowed to burst up to the full egress bandwidth of the uplink port, but when congestion occurs, will be throttled back in favour of Gold traffic, and will share...

Page 15 | AlliedWare™ OS How To Note: QoS configuration Full QoS scenario 1 : tiered services for a single customer The act of assigning packets in a particular traffic class to a particular egress queue is achieved in the pre-marking process. This requires that the pre-marking DSCP map table be set...
