Configuring Quality of Service Features

To set the QoS mapping, proceed as follows:
1. To configure mapping of the 802.1p priority levels to internal transmit queue values, see
Configuring Priority Value Mapping to QoS
To set the QoS priority assignment (on Rx traffic), proceed as follows:
1. To assign a priority to the incoming traffic per port, see
on a Port.
2. To set QoS priority manually per destination MAC address, see
Address
3. To set priority for traffic flow, see chapter "Configuring Access Control Lists (ACL)".
4. To remark the DSCP field in the IP header, see chapter "Configuring Access Control Lists
(ACL)".
To Set DSCP-to-CoS mapping
Set the DSCP-to-CoS mapping. See
1.
Set ACL on the traffic on which the user wants to apply DSCP-to-CoS (use the access-list
2.
command in Global Configuration mode). For more information, see chapter "Configuring
Access Control Lists (ACL)".
Apply the ACG on the incoming interface/VLAN with the option keyword (use the ip access-
3.
group command in Interface/VLAN Configuration mode). For more information see,
"Configuring Access Control Lists (ACL)".
Use the set traffic-class command in Interface or VLAN ACG Configuration mode for
4.
applying the DSCP-to-CoS settings on the incoming traffic.
To override QoS scheduling algorithm settings:
see QoS Tx Scheduling
To set traffic shaping on Tx traffic:
see Configuring Traffic Shaping.
To set the congestion management algorithm (Tail-drop or WRED) and thresholds:
see QoS Congestion Avoidance
