CoS Weighting
During traffic bursts, frames queued in the switch pending transmission on a port
may have both high and normal priorities. This parameter specifies the weighting
algorithm for transmitting high priority CoS and normal priority CoS frames.
Some examples include:
1:1 - 1 high priority frame is transmitted for every normal priority frame
