Ethernet controller: Onboard or not

amit mehta_2 — Wed, 23 Jan 2008 11:56:57 GMT

Hi,

The output of 'lspci' on one of my server
points to two broadcom controllers.
Just by looking at the lspci output,is it possible to determine if any of these controllers are on board or not ?

snip from lspci -m

04:00.0 "Ethernet controller" "Broadcom Corporation" "Broadcom NetXtreme II BCM5708 1000Base-T" -r12 "Hewlett-Packard Company" "7038"

42:00.0 "Ethernet controller" "Broadcom Corporation" "Broadcom NetXtreme II BCM5708 1000Base-T" -r12 "Hewlett-Packard Company" "7038"

it is very possible that you have two onboard controllers.

Hi vitaly,

i don't have access to the lab, and to get that
i'll have to go through a long procedure,therefore is it possible to come to a conclusion by just looking at output of 'lspci' or some other utils ?

You can try dmidecode. Acording to the dmidecode documentation, it will report the DMI Type for the device, being 10 On Board Devices.

if my version is right, you'll see sequential MAC addresses into "ifconfig -a" output.

Thanks Ivan,

The dmidecode output on my server indicates that i have no on-board devices.

[root@blr-km-cpd-101 root]# dmidecode |grep -i type\ 10
[root@blr-km-cpd-101 root]# echo $?
