Version Description
8.3.1.0 Introduced.
Usage Information By default, when rate policing and shaping, the system does not include the Preamble, SFD, or the IFG
elds. These elds are overhead; only the elds from MAC destination address to the CRC are used for
forwarding and are included in these rate metering calculations.
Per-Port QoS Commands
Per-port QoS (port-based QoS) allows you to dene the QoS conguration on a per-physical-port basis.
dot1p-priority
Assign a value to the IEEE 802.1p bits on the trac this interface receives.
Syntax
dot1p-priority priority-value
To delete the IEEE 802.1p conguration on the interface, use the no dot1p-priority command.
Defaults none
Command Modes INTERFACE

Usage Information
The dot1p-priority command changes the priority of incoming trac on the interface. The system
places trac marked with a priority in the correct queue and processes that trac according to its queue.
When you set the priority for a port channel, the physical interfaces assigned to the port channel are
congured with the same value. You cannot assign the dot1p-priority command to individual
interfaces in a port channel.
