ROUPINGS
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.
