Display or change the port default Class-of Service (CoS) transmit priority (0 through 7) of each
port for frames that are received (ingress) without priority information in their tag header.
•
Display the current traffic class mapping-to-priority of each port.
•
Set each port to transmit frames according to 802.1D (802.1p) priority transmit queues set in the
frame header.

)
•
set port priority (

priority settings configured with the
