Hi All,
Does anyone know exactly how the "wrr-queue dscp-map" interface config
command is used on a Catalyst 3550?
From DocCD I understand it's used on the ingress interface to map trusted
DSCP values to WRED thresholds (1 or 2). I mean, this happens before DSCP
mutation (if one is configured) takes action?
If DSCP mutation is configured, regardless of what the "mutated" internal
DSCP value is and the resultant mapped COS value is before egress
scheduling, the packets will be assigned to the WRED threshold which we
specified earlier on the ingress interface?
Please help me understand better.
Thank you.
B.Rgds,
Lim TS
