ROUPINGS
Ingress 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] <ip_destination_address>/<mask_length>
qosprofile <qosname>
• Destination MAC address — When making a permanent FDB entry, you can provide
a QoS profile. You can also provide a QoS profile that will be bound to a dynamic
FDB entry when the MAC address is learned. This is configured using the following
command:
create fdbentry <mac addr> vlan <vlan name> [blackhole | port
<slot:portlist> | dynamic] qosprofile <qosname>
For example:
create fdbentry 00:11:22:33:44:55 vlan default port 4:1 qosprofile

• IEEE 802.1p — When traffic that contains 802.1p prioritization bits are seen, the
traffic is mapped to the four default QoS profiles. No user configuration is required
for this type of traffic grouping. Table 7-2 describes 802.1p values and their
associated QoS profiles.
