Command
History
Version 9.2(0.0) Introduced on the M I/O Aggregator. This command is
supported in Programmable-Mux (PMUX) mode only.
Version 8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
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.
