SMC Networks 10/100 manual Setting the Queue Mode

CONFIGURING THE SWITCH

This switch uses Weighted Round-Robin as the default mode for each port. Up to 8 separate traffic classes are defined in IEEE 802.1p. The default priority levels are assigned according to recommendations in the IEEE 802.1p standard as shown in the following table.

Priority

Inbound frames that do not have VLAN tags are tagged with a default service priority of zero, and placed in queue 1 at the output port. Therefore, any inbound frames that do not have priority tags will be placed in queue 1 of the output port. (Note that if the output port is an untagged member of the associated VLAN, these frames are stripped of all VLAN tags prior to transmission.) However, if the incoming frame is an IEEE 802.1Q VLAN tagged frame, the IEEE 802.1p User Priority bits will be used.

Setting the Queue Mode

You can set the queue mode to strict priority or Weighted Round-Robin (WRR) for the four class of service (CoS) priority queues. The default queue mode is WRR.
