Verify the CoS value of the port. If no port is specified, it displays the CoS values of all ports.
port-list:
The list of Ethernet ports.
lagid-list:
The list of LAGs.
Step 6
end
Return to privileged EXEC mode.
Step 7
copy running-config startup-config
Save the settings in the configuration file.
Note:
All the ports in the same LAG should be assigned with the same port priority.
The following example shows how to map port 1-3 to TC1, and keep other mapping
relations as default:
