ii. Create a new policy file (say new_policy_file ) and add the following line to associate
connections with the given scheduling class.:
src host 102.1.1.1 => offload class 0
iii. Compile the policy file using COP
[root@host~]# cop -d –o <output_policy_file> <new_policy_file>
iv. Apply the COP policy:
[root@host~]# cxgbtool eth0 policy <output_policy_file>
v. Set the appropriate rule for class 0
[root@host~]# cxgbtool ethX sched-class params type packet level cl-rl
mode class rate-unit bits rate-mode absolute channel 0 class 0 max-rate
300000 pkt-size 1460
5.3. Offloaded Connections with Modified Application
The following example demonstrates the method to rate limit all TCP connections on class 0 to
a rate of 300 Mbps for for offloaded connections with modified application.
i. Load the TOE driver and bring up the interface.
[root@host~]# modprobe t4_tom
[root@host~]# ifconfig eth0 up
ii. Modify the application as mentioned in the Configuring Traffic Management section.
iii. Set the appropriate rule for class 0
[root@host~]# cxgbtool ethX sched-class params type packet level cl-rl
mode class rate-unit bits rate-mode absolute channel 0 class 0 max-rate
300000 pkt-size 1460
