Configuring Chelsio Network Interfaces

To test Chelsio adapters' features it is required to use two machines both with Chelsio's 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
/etc/sysconfig/network-scripts
kept under
Some operating systems may attempt to auto-configure the detected hardware
Note
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.

Configuring Adapters

T6 Unified wire adapters support auto-negotiation (enabled by default) which allows link
parameters like speed, duplex, FEC and Pause to be negotiated with the PEER.
Setting FEC
100G, 50G and 25G speeds support changing Forward Error Correction (FEC). The existing
FEC settings can be viewed using:
[root@host~]# cxgbtool <ethX> fec
Below is a sample output on T6 100G port:
RS FEC is set by default for the T6 port at 100G speed. Configure the same FEC on the PEER
for the link to come up. To set FEC:
[root@host~]# cxgbtool <ethX> fec <value>
Here value can be:
rs: Reed-Solomon FEC
baser: Base-R/Reed-Solomon FEC
auto: Use standard FEC settings as specified by IEEE 802.3 interpretations of Cable
Transceiver Module parameters.
off: Turn off FEC
