Configuring WFQ
You must enable the rate limit function for the queuing function to take effect on these interfaces:
tunnel interfaces, subinterfaces, Layer 3 aggregate interfaces, HDLC link bundle interfaces, RPR
logical interfaces, and VT interfaces configured with PPPoE, PPPoA, or PPPoEoA.
On an interface without WFQ configured, the
qos wfq
command can enable WFQ and configure
WFQ-related parameters. If WFQ is configured for the interface, the
qos wfq
command can modify
the WFQ-related parameters.
To configure WFQ:
