• PAC E — When 3Com PACE traffic is seen, it is mapped to the profile named qp3.
Observance of PACE can be controlled by using the following command:
{enable | disable} pace
• Source port — You can configure a QoS profile to all the traffic being received from a
particular port. This is controlled by using the following command:
config port <port:portlist> qosprofile <qosname>
• VLAN — This is controlled by using the following command:
config vlan <name> qosprofile <qosname>

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.

RECEDENCE
If traffic falls into multiple traffic groupings, the following order of precedence applies:
Ingress mode
• IP destination address
• Destination MAC address
• 802.1p prioritization bits
• PACE
• Source port
• VLAN
