Packet Groupings
This category of traffic groupings consists of the following:
❑ Prioritization bits used in IEEE 802.1p packets
❑ PACE packets
802.1p Packets. When traffic that contains 802.1p prioritization bits is
seen, the traffic is mapped to the four default QoS profiles. No user
configuration is required for this type of traffic grouping. This
grouping is available only in ingress mode.
Table 7-4 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
The default setting disabled. This option is available only in ingress
mode.
