LAN Based QoS

Morning All, I have applied LAN based QoS (WRR with a priority queue) to a 2950-E. Because the queueing config is applied globally it is unclear as to when it actually begins prioritising traffic. Is it all of the time, or simply when there is congestion on the switch? Thanks.

Hello,

when there is no congestion the switch cannot apply prioritization, because that would mean altering the natural order in which packets are received.

Thats great, thank you for your help. Raj.
