Binding NIC to CPU

[AnotherAlan]

Hi all,

I am running redhat4 enterprise on an ibm3550 with 2 x cpu and 2 x nic.
I have been asked to bind each nic to one cpu.

Unfortunately I don't go on my redhat course till next week.
Anyone care to help me with this?

Thanks

I have figured it out.

/proc/irq/**/smp_affinity.

If anyone is interested...

No, but it is fascinating.. why did they want it in the first place?

To ensure that TCP and UDP requests are handled by the same cpu for consistency.
