Egress traffic groupings include the following:

IP destination address — A specific QoS profile can be associated with an IP 
destination address, or range of IP destination addresses specified using a subnet 
mask. The QoS parameters are dynamically associated with a route when the route 
table is built. This is controlled by the following command:

config ipqos [add | delete] <destination_address> qosprofile 

<qosname>

Destination MAC address — Configuration is as described in the section, “Ingress 
Traffic Groupings,” except that bandwidth parameters of the QoS profile are 
observed.

VLAN — Configuration is as described in the section, “Ingress Traffic Groupings,” 
except that bandwidth parameters of the QoS profile are observed. 

In order to use ipqos traffic groupings, you must change the devicemode of the 
switch to 

ipqos

, before configuring QoS.

If traffic falls into multiple traffic groupings, the following order of precedence applies:

IP destination address

Destination MAC address

802.1p prioritization bits

PACE

Source port

VLAN

IP destination address
