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 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.
Policy-Based QoS Commands
Policy-based trac classication is handled with class maps. These maps classify data trac 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.
