Bus Address: 0000:01:00.1
Reference Designation: Integrated NIC 3
Bus Address: 0000:09:00.0
Reference Designation: Integrated NIC 4
Bus Address: 0000:09:00.1
c. Correlate the list of OS/Ethernet interface names to a logical bus address:
ip a | grep ": " | awk '{print $2}' | tr -d ":" | grep -v ^"lo"$ | xargs -I '{}' sh -
c 'echo {}; ethtool -i {} | grep bus-info'
This command displays the Ethernet network names (enXXX) of the interfaces and the correlating logical bus
address (without the loopback). For example:
em1
bus-info: 0000:19:00.0
p1p1
bus-info: 0000:3b:00.0
em2
bus-info: 0000:19:00.1
em3
bus-info: 0000:19:00.2
em4
bus-info: 0000:19:00.3
p1p2
bus-info: 0000:3b:00.1

2. Create a table for your own use, similar to the example table shown below:
l
Base the table on the RHEL port definitions described for the relevant server type in the R840 port
designation topic.
l
In the Port row, record the enXXX names that correspond with the PCIe slots.
l
Map each line in turn from the output in substep a to the corresponding line in the output from substep b.
