NIC naming scheme


Hello All

I'm going through this website about NIC naming schemes. In it about Scheme 3, it mentions,
Quote:
Scheme 3: Names incorporating physical location of the connector of the hardware (example: enp2s0), are applied if applicable, else falling directly back to scheme 5 in all other cases.
My NIC has this name:
Code:
$ ip link show
2: enp3s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000
    link/ether 00:00:00:00:00:00 brd ff:ff:ff:ff:ff:ff
So, according to this website, My NIC name can be broken down as,

en --- ethernet
p3 --- bus no 3
s0 --- slot no 0

So, how do I verify this? My lspci looks like this:
Code:
$ lspci | grep Ethernet
03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 11)
Is '03' at beginning of the line is bus no? What about slot no? the next '00'?

Thanks

ddenial,

You seem to be doing fine and appear to have answered your own question.

If you use the lspci command, the output will list all your PCI devices with their bus numbers etc.

This link may help you:

...are commonly referred to as the device's BDF or B/D/F (for bus/device/function).
So the device and slot are the same?

denial,

11.3:
https://access.redhat.com/documentat...e_device_names

Example:
[P<domain>]p<bus>s<slot>[f<function>][d<dev_id>]
PCI geographical location. In PCI geographical location, the [P<domain>] number is only mentioned if the value is not 0.

For example:
ID_NET_NAME_PATH=P1enp5s0

"en --- ethernet
p3 --- bus no 3
s0 --- slot no 0"


Some more information

"
Names incorporating Firmware/BIOS provided index numbers for on-board devices (example: eno1)
Names incorporating Firmware/BIOS provided PCI Express hotplug slot index numbers (example: ens1)
Names incorporating physical/geographical location of the connector of the hardware (example: enp2s0)
Names incorporating the interfaces's MAC address (example: enx78e7d1ea46da)
Classic, unpredictable kernel-native ethX naming (example: eth0)
