Users Guide

You can apply this command on both physical interfaces and port channels. When you set the service-
class dynamic for a port channel, the physical interfaces assigned to the port channel are automatically
configured; you cannot assign the service-class dynamic command to individual interfaces in a
port channel.
● All dot1p traffic is mapped to Queue 0 unless you enable the service-class dynamic dot1p
command on an interface or globally.
● Layer 2 or Layer 3 service policies supersede dot1p service classes.
