5. Configuring Chelsio Network Interfaces

In order to test Chelsio adapters’ features it is required to use two machines both with Chelsio’s

(T5, T4 or both) network adapters installed. These two machines can be connected directly

without a switch (back-to-back), or both connected to a switch. The interfaces have to be

declared and configured. The configuration files for network interfaces on Red Hat Enterprise

Linux (RHEL) distributions are kept under /etc/sysconfig/network-scripts.

5.1. Configuring 40G adapters

Chelsio T5 40G adapters can be configured in the following two modes:

i. 2X40Gbps: This is the default mode of operation where each port functions as 40Gbps link.

ii. 4X10Gbps: In this mode, port 0 functions as 4 10Gbps links and port 1 is disabled.

To configure/change the mode of operation, use the following procedure:

i. Unload all Chelsio drivers using the rmmod command:

[root@host]# rmmod <chelsio_driver>

ii. Run the chelsio_adapter_config command to detect all T5 40G adapter(s) present in the

system.

[root@host]# chelsio_adapter_config

Chelsio T580 card detected

Chelsio T580 PCI devices :

|------------------------------|

| 1 T580-LP-CR 01:00.0 |

| 2 T580-CR 03:00.0 |

| 3 T580-LP-SO-CR 04:00.0 |

|------------------------------|

iii. Select the adapter to configure by specifying the adapter index.

Some operating systems may attempt to auto-configure the detected hardware

and some may not detect all ports on a multi-port adapter. If this happens,

please refer to the operating system documentation for manually configuring the

network device.
