Scheduling traffic for forwarding

The values of the remaining queues are calculated to be the following.
q2 = 30%, q1 = 20%, and q0 = 10%
Configuring WFQ destination-based traffic scheduling
To configure WFQ destination-based scheduling use a command such as the following.
BigIron RX(config)# interface ethernet 1/1
BigIron RX(config-if-e1000-1/1)# qos scheduler destination-weighted 5 10 15 20
Syntax: qos scheduler destination-weighted <queue0-weight> <queue1-weight> <queue2-weight>
<queue3-weight>
The <queue0-weight> variable defines the relative value for queue0 in calculating queue0’s
allocated bandwidth.
The <queue1-weight> variable defines the relative value for queue1 in calculating queue1’s
allocated bandwidth.
The <queue2-weight> variable defines the relative value for queue2 in calculating queue2’s
allocated bandwidth.
The <queue3-weight> variable defines the relative value for queue3 in calculating queue3’s
allocated bandwidth.
Refer to “Calculating the values for WFQ source and destination-based traffic scheduling” for
information on assigning queue0-weight to queue3-weight values.
Configuring WFQ source-based traffic scheduling
To configure WFQ source-based scheduling use a command such as the following.
BigIron RX(config)# interface ethernet 1/1
BigIron RX(config-if-e1000-1/1)# qos scheduler source-weighted 25 25 25 25
Syntax: qos scheduler source-weighted <Queue0-weight> <Queue1-weight> <Queue2-weight>
<Queue3-weight>
The <Queue0-weight> variable defines the relative value for queue0 in calculating queue0’s
allocated bandwidth.
The <Queue1-weight> variable defines the relative value for queue1 in calculating queue1’s
allocated bandwidth.
The <Queue2-weight> variable defines the relative value for queue2 in calculating queue2’s
allocated bandwidth.
The <Queue3-weight> variable defines the relative value for queue3 in calculating queue3’s
allocated bandwidth.
Refer to “Calculating the values for WFQ source and destination-based traffic scheduling” for
information on assigning queue0-weight to queue3-weight values.
Configuring maximum rate-based traffic scheduling
To configure maximum rate-based scheduling use a command such as the following.
BigIron RX(config)# interface ethernet 1/1
BigIron RX(config-if-e1000-1/1)# qos max-rate 100 100 100 100
