Extreme Networks Summit1 2802.1p Values and Associated QoS Profiles, 802.1p Value QoS Profile

QUALITY OF SERVICE (QOS)

•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 <portlist> dynamic] qosprofile <qosname>

For example:

create fdbentry 00:11:22:33:44:55 vlan default port 1 qosprofile qp1

•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 8-2 describes 802.1p values and their associated QoS profiles.

•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 <portlist> qosprofile <qosname>

•VLAN — This is controlled by using the following command: config vlan <name> qosprofile <qosname>
