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.
Policy-Based QoS Commands
Policy-based traffic classification is handled with class maps. These maps classify data traffic into one of eight classes . Dell Networking OS
enables you to match multiple class maps and specify multiple match criteria. Policy-based QoS is not supported on logical interfaces, such
as port-channels, VLANS, or loopbacks.
