Egress Traffic Groupings; Precedence - Extreme Networks BlackDiamond 6800 User Manual

• PACE — 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>

GRESS
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,
Traffic
observed.
• VLAN — Configuration is as described in the section,
except that bandwidth parameters of the QoS profile are observed.

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