NIC limit in kernels

vishamr2000 · 05-20-2005, 01:34 AM

Hi to all,

I would like to know if there's a limit in the number of NICs that can be installed in a Linux machine. I know that older kernels had a limit for the number of NICs that they can support. But what abt 2.6 kernels?

Thx in advance...

Regards,
Visham

I'd assume you'd be limited by the hardware in terms of the number of buses/interrupts in the system long before you reached the OS maximum. For virtual interfaces (aliases) you can at least have several thousand (you'd need a whole lot o' PCI slots to reach that).

I'm not sure if their is a limit, but I have one firewall that currently has 14 ethernet ports. 2 builtin ports and 3 quad port 10/100 nics.
