Usage Information
To honor all incoming 802.1p markings on incoming switched trac on the interface, enter this command. By
default, this facility is not enabled (that is, the 802.1p markings on incoming trac are not honored).
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
congured; you cannot assign the service-class dynamic command to individual interfaces in a port
channel.
• All dot1p trac 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.
