Set dot1p Priorities for Incoming Traffic
Change the priority of incoming traffic on the interface using the dot1p-priority command from
INTERFACE mode, as shown in Figure 37-2. FTOS places traffic marked with a priority in a queue based
on Table 37-2. If you set a dot1p priority for a port-channel, all port-channel members are configured with
the same value. You cannot assign a dot1p value to an individual interfaces in a port-channel.
Figure 37-2. Configuring dot1p Priority on an Interface
Honor dot1p Priorities on Ingress Traffic
By default, FTOS does not honor dot1p priorities on ingress traffic. To honor dot1p priorities on ingress
traffic, use the
service-class dynamic dot1p command from INTERFACE mode, as shown in Figure 37-3.
You can configure this feature on physical interfaces and port-channels, but you cannot configure it on
individual interfaces in a port channel.
FTOS Behavior: The S-Series distributes eight dot1p priorities across four data queues. (Table 37-2).
