c. Correlate the list of OS 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:
Base the table on the RHEL port definitions for the relevant server type
l
described in VxFlex Ready Node R640 and R740xd port designations - Linux
on page 40.
In the Port row, record the enXXX names that correspond with the PCI
l
slots.
Map each line in turn from Step
l
line in Step 1.b on page 42 output.
Note
In 1U1N and 2U1N platforms, the 1 GB port on the right is used for management,
and the left 10 GB ports on both NICs are used for data.
For example, the last column in the following table was created using the
information from the 4th line in steps
VxFlex OS role
Port
1.a on page 42 output to the corresponding
1.a on page 42 and
... Optional VxFlex OS Data2 2nd port
