Set Dot1P Priorities For Incoming Traffic; Honor Dot1P Priorities On Ingress Traffic - Dell Force10 MXL Blade Configuration Manual

Set dot1p Priorities for Incoming Traffic

Change the priority of incoming traffic on the interface using the
INTERFACE mode
the corresponding queue as shown in
port-channel members are configured with the same value. You cannot assign a dot1p value to individual
interfaces in a port-channel.
FTOS Behavior: The MXL Switch distributes eight dot1p priorities across four data queues.

Note: The dot1p-priority command marks all incoming traffic on an interface with a specified dot1p priority
and maps all incoming traffic to the corresponding queue
on an interface, incoming traffic with a specified dot1p priority can be distributed across different queues.
Therefore, when you use PFC and ETS to manage data center traffic, it is not recommended that you use
the dot1p-priority command to set a queue assignment. See
information.

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
configure this feature on physical interfaces and port-channels, but you cannot configure it on individual
interfaces in a port channel.
