a. Correlate the physical PCIe slot to a logical bus address:
dmidecode -t slot |egrep "Designation|Current Usage|Bus
Address"
This command displays the PCI location of each PCIe card. In the following
sample output, the logical bus address in the last three lines is
"0000:05:00.0," which is shown as Current Usage: In Use and
correlates to physical PCIe card slot location "PCIe Slot 6."
In this case, the 10GB PCI NIC is presented on slot 6, and the logical bus
address of its ports is 5:0 and 5:1. (See
correlation between PCIe slot and the logical bus address is highlighted in
yellow.)
Designation: PCIe Slot 1
Current Usage: Available
Designation: PCIe Slot 2
Current Usage: Available
Designation: PCIe Slot 3
Current Usage: Available
Designation: PCIe Slot 4
Current Usage: Available
Designation: PCIe Slot 5
Current Usage: Available
Designation: PCIe Slot 6
Current Usage: In Use
Bus Address: 0000:05:00.0
b. Correlate the onboard device name (NIC1 to NIC4) to a logical bus address:
dmidecode -t baseboard | sed -n -e '/NIC/,/Bus Address/p' |
egrep "NIC|Bus Address"
This command displays the onboard location of each NIC port, In the
following sample output, the logical bus address in the first two lines is
"0000:01:00.0" which correlates to physical NIC Integrated NIC 1.
Reference Designation: Integrated NIC 1
Bus Address: 0000:01:00.0
Reference Designation: Integrated NIC 2
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 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'
