Version Description
6.1.1.1 Introduced on the E-Series.
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.

Usage
Information
After you configure a unicast queue as strict-priority, that particular queue, on the entire chassis, is
treated as a strict-priority unicast. Traffic for a strict priority is scheduled before any other
queues are serviced. For example, if you send 100% line rate traffic over the SP queue, it starves all other
queues on the ports on which this traffic is flowing.
