Egress port and priority based rate shaping

Example of configuring Prioritized Voice over Data
When configuring Prioritize Voice over Data, use the strict priority method.
In the example below, the DSCP 46 (Voice) is assigned to high priority queue on Ingress port, and
goes out of Egress port without changing the DSCP value in the packet.
Brocade(config)#int e 1/5
Brocade(config-if-e1000-1/5)#qos scheduler strict
Brocade(config-if-e1000-1/5)#int e 1/6
Brocade(config-if-e1000-1/6)#qos scheduler strict
Brocade(config-if-e1000-1/6)#int e 1/13
Brocade(config-if-e1000-1/13)#qos dscp encode-policy off
Brocade(config-if-e1000-1/13)#qos scheduler strict
Use the show qos-map dscp decode-map default-map command to verify DSCP 46 is going to the
high priority queue as highlighted below.
Brocade(config)#show qos-map dscp decode-map default-map
