Important

• Intel SFP+ 10Gb/sec is the only one supported by default on the standard Linux driver. TRex also supports Cisco

10Gb/sec SFP+.

• For operating high speed throughput (example: several Intel XL710 40Gb/sec), use different NUMA nodes for different

NICs.

To verify NUMA and NIC topology: lstopo (yum install hwloc)

To display CPU info, including NUMA node: lscpu

NUMA usage: example [numa-example]

• For the Intel XL710 NIC, verify that the NVM is v5.04. Info [xl710-ﬁrmware].

Note

Purchase the 10Gb/sec SFP+ separately. Cisco would be ﬁne with TRex (but not for plain Linux driver).
