CONFIGURING THE SWITCH

Setting the Default Priority for Interfaces

You can specify the default port priority for each interface on the switch. All untagged packets entering the switch are tagged with the specified default port priority, and then sorted into the appropriate priority queue at the output port.

Command Usage

This switch provides four priority queues for each port. It uses Weighted Round Robin to prevent head-of-queue blockage.

The default priority applies if the incoming frame is an untagged frame received from a VLAN trunk or a static-access port. 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.

If the output port is an untagged member of the associated VLAN, these frames are stripped of all VLAN tags prior to transmission.

Command Attributes

Default Priority – The priority that is assigned to untagged frames received on the specified port. (Range: 0 - 7, Default: 0)

Number of Egress Traffic Classes – The number of queue buffers provided for each port.

2-54
