Red Hat Enterprise Linux 4/5/6
- I am trying to locate the device ID on my network cards but I cannot find that specific information, I need that information to upgrade my drivers.
- How to findout the Device ID of Network Card ?
The command lspci will show you the Device ID of your Network Card or any other pci device . Depending on your system you may be able to run this command without having to be root first.
Try -nvv options with the lspci commad to get the Device ID of network card.
This options will display lspci output in verbose mode with the numbers without performing a lookup in the device id list.
lspci shows the following nic card on my system:
09:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5752 Gigabit Ethernet PCI Express (rev 02)
lspci -nvv shows
+------- vendor id (Broadcom)
| +--- device id
