This command sets a	no switchport priority default

	The priority is a number from 0 to 7. Seven is the highest priority.

	Command Mode: Interface Configuration (Ethernet, Port Channel)
	Command Usage: The precedence for priority mapping is IP Port, IP Prece-
	dence or IP DSCP, and default switchport priority.
	The default priority applies for an untagged frame received on a port set to accept
	all frame types (i.e, receives both untagged and tagged frames). This priority does
	not apply to IEEE 802.1Q VLAN tagged frames. If the incoming frame is an IEEE
	802.1Q VLAN tagged frame, the IEEE 802.1p User Priority bits will be used.
	This switch provides eight priority queues for each port. It is configured to use
	Weighted Round Robin, which can be viewed with the show queue bandwidth
	command. Inbound frames that do not have VLAN tags are tagged with the input
	port’s default ingress user priority, and then placed in the appropriate priority
	queue at the output port. The default priority for all ingress ports is zero. There-
	fore, any inbound frames that do not have priority tags will be placed in queue 0 of
	the output port. (Note that if the output port is an untagged member of the associ-
	ated VLAN, these frames are stripped of all VLAN tags prior to transmission.)
	Example: The following example shows how to set a default priority on port 3 to
	5:
	Console(config)#interface ethernet 1/3
	Console(config-if)#switchport priority default 5
queue bandwidth	Syntax:
This command assigns	queue bandwidth weight1...weight4
weighted round-robin	no queue bandwidth
	• weight1...weight4 - The ratio of weights for queues 0-3 determines the weights
(WRR) weights to the four
	used by the WRR scheduler. However, note that Queue 0 is fixed at a weight of

priority queues.
	Default Setting: Weights 1, 2, 4, 6 are assigned to queues 0-3 respectively.
Use the no form to restore
the default weights.	Queue 0 is non-configurable.
	Command Mode: Global Configuration
	Command Usage: WRR controls bandwidth sharing at the egress port by defin-
	ing scheduling weights.
	Example: This example shows how to assign WRR weights to priority queues
	1 - 3:
	Console(config)#queue bandwidth 6 9 12
	Console(config)#
