Introduced on Z9000 Expanded command to permit configuration on port channels Usage Information Enter this command to honor all incoming 802.1p markings, on incoming switched traffic, on the interface. By default, this facility is not enabled (that is, the 802.1p markings on incoming traffic are not honored). This command can be applied 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. On the S-Series all traffic is by default mapped to the same queue, Queue 0. If you honor dot1p on ingress, then you can create service classes based the queueing strategy using the command service-class dynamic dot1p from INTERFACE mode. You may apply this queuing strategy to all interfaces by entering this command from CONFIGURATION mode. • All dot1p traffic is mapped to Queue 0 unless service-class dynamic dot1p is enabled on an interface or globally. • Layer 2 or Layer 3 service policies supercede dot1p service classes.
