4.2.2. For Offloaded connections
Traffic Management of offloaded connections can be configured either by applying COP policies
that associate offloaded connections to classes or by modifying the application.
Both the methods have been described below:
Applying COP policy
i. Load the TOE driver and bring up the interface:
[root@host~]# modprobe t4_tom
[root@host~]# ifconfig ethX up
ii. Create a new policy file (say new_policy_file ) and add the following line to associate
connections with the given scheduling class.
E.g.:
src host 102.1.1.1 => offload class 0
The above example will associate all connections originating from IP address 102.1.1.1 with
scheduling 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 ethX policy <output_policy_file>
Where,
ethX : Chelsio interface
For more information on additional parameters, refer cop manual by running the
man cop command.
