Larger values of N reduce the effect ofinstantaneous changes. To update the current queue size to ½ the differencebetween the previous size and the current instantaneous queue size, set theweighting constant to 1. To update the current queue size to 1/4 thedifference between the previous size and the current instantaneous queuesize, set the weighting constant to 2, ....redirectUse the redirect command in Policy-Class-Map Configuration mode tospecify that all incoming packets for the associated traffic stream areredirected to a specific egress interface (physical port or port-channel).
