> Greetings,
>
> We have a e4500 Server running Solaris 8 that has dual nics...

> NIC1: GE0
> NIC2: HME0
>
> I had setup multipathing to fail from the GE0 -> HME0. This worked
perfectly, until we had a router failure the other day.
>
> The machine dropped off the network because both interfaces could not reach
the router. To prevent this from happening again, I want to configure GE0 to
probe the switch it is plugged into and HME0 the other switch. Ge0 is on
switch 172.24.24.10 and hme0 is on 172.24.24.12
