hi all,

in solaris 10 u8, how do i prioritize
(give priority to) one of 2 available
nics for traffic?

how can i fall back to the slower one
(100mbit/s) only if the faster one (1000mbit/s)
fails?

thanks
chris

for clarification:

when i start browsing a website on that
system, i'd like it to use interface 1 with
ip adress (a) by default instead of
interface 2 with ip address (b).

IPMP?

Put them both in the same IPMP group and mark the slower one standby.

Note that I'm not sure that mixing speeds in an IPMP group is supported.

That must be wonderful! I don't understand it at all.
