How to configure 2 NICs to a Single IP in OS X
I have a beige G3 running OS X Server 10.2. The beige G3 has a 10 baseT on-board NIC (Apple OEM integrated on the mobo), as well as a PCI-based 10/100 Asante NIC.
Is there a way to bind BOTH NICs to the same IP, in such a way that if one NIC fails, the other NIC "kicks in" and provides redundnacy?
I have been able to give each NIC a seperate IP (i.e.; NIC #1 @10.0.1.10, and NIC #[email protected]), but that is not what I want. I want BOTH NICs to be bound to the same IP.

I don't think this is possible in OS X.

I think that you have to
Maybe someone who knows how to write shell scripts can help you more

You could write a shell script to ping an address, and if that fails, change your ip address using ifconfig (eg ifconfig en0 10.0.0.3/16)

What does the "/16" represent?

/16 means the subnet mask is 255.255.0.0 (the first 16 bits are 1).

Your examplw shas that the /16 refers to a class B subnet mask (255.255.0.0). Please give me another example of a fractional subnet mask value -but for this (class C) subnet mask: 255.255.255.0.
Would it be /24? /8? /32? /16?

A subnet mask of 255.255.255.0 would be /24.
There's a subnet mask converter on this page: http://www.telusplanet.net/public/sparkman/netcalc.htm
When I plug my PowerBook into wired ethernet (rare), the only difference is that things are faster.
Nothing changes.
So.
What you want to do should be possible. Just set them both to the same IP address and let the OS take care of the rest. Have you actually been unable to set them both to the same IP address using System Preferences?
