Physical and Logical Groupings

802.1p Packets

When traffic that contains 802.1p prioritization bits is seen, the traffic is mapped to the eight default QoS profiles. No user configuration is required for this type of traffic grouping. Table 27 describes 802.1p values and their associated QoS profiles.

To modify the default behavior of 802.1p values and associated QoS profiles, use the following commands:

config dot1p type <dot1p_value> qosprofile <qosname>

This command changes the default mapping of 802.1p values and QoS profiles.

enable dot1p replacement ports [<portlist> all]

This command allows the switch to overwrite the ingress 802.1p value with the value configured for the QoS profile.

Two traffic groupings exist in this category:

■Source port

■VLAN
