NIC name definition
Hi, we have R750 RAC server with four NIC the table look as follow:
2: eno8303: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
link/ether ec:2a:72:0a:05:66 brd ff:ff:ff:ff:ff:ff
altname enp4s0f0
inet 130.237.89.52/25 brd 130.237.89.127 scope global eno8303
valid_lft forever preferred_lft forever
inet6 fe80::ee2a:72ff:fe0a:566/64 scope link
valid_lft forever preferred_lft forever
3: eno12399np0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
link/ether 5c:6f:69:75:6e:b0 brd ff:ff:ff:ff:ff:ff
altname enp49s0f0np0
4: eno8403: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
link/ether ec:2a:72:0a:05:67 brd ff:ff:ff:ff:ff:ff
altname enp4s0f1
5: eno12409np1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
link/ether 5c:6f:69:75:6e:b1 brd ff:ff:ff:ff:ff:ff
altname enp49s0f1np1
6: enp152s0f0np0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
link/ether 5c:6f:69:be:83:80 brd ff:ff:ff:ff:ff:ff
7: enp152s0f1np1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
link/ether 5c:6f:69:be:83:81 brd ff:ff:ff:ff:ff:ff
When I look at the back of the server I know which are eno8303 and eno8403 but how can I determin the rest of them?

go into idrac gui, look at network cards, view the mac addresses, then compare to your list above.

I know they aught to be listed in idrac but how is text info in idrac able to point to corresponding physical sockets on the rear of the chassi? Or am I missing something here?

if you look at this manual starting on Page 13, it shows you the layout of the nics/slots. Most operating systems enumerate the nics starting with the (if equipped):
LOM - idrac will list this as the embedded nic
OCP - idrac will list this as the intergrated nic
Slotted nics - idrac will list these as Slot 1, Slot 2 etc.
Each nic usually has the port number written on the card, but if not, port 1 of the nic is always the one closest to the top of the card.
