Usage Information
To honor all incoming 802.1p markings on incoming switched traffic on the
interface, enter this command. By default, this facility is not enabled (that is, the
802.1p markings on incoming traffic 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 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.
bandwidth-percentage
Assign a percentage of weight to the class/queue.
Syntax
bandwidth-percentage percentage
To remove the bandwidth percentage, use the no bandwidth-percentage
command.
