Set dot1p Priorities for Incoming Traffic
Change the priority of incoming traffic on the interface using the command dot1p-priority from
INTERFACE mode, as shown in Figure 38-209. FTOS places traffic marked with a priority in a queue
based on Table 38-81. 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 38-209. Configuring dot1p Priority on an Interface
FTOS Behavior: The C-Series and S-Series distribute eight dot1p priorities across four data queues. This is
different from the E-Series, which distributes eight dot1p priorities across eight queues (Table 38-81).
