[SunHELP] Help Needed with Mutiple Network interfaces

[Rajesh Vadde]

Thanks Dale,
That's what I found yesterday from net. Is there any way oher than Multi
Pathing? Sun Trunking also can be used, but looks like it has been told that
Sun does not suport Trunking on Fire 4800 Servers :-|.

Thanks and regards
Rajesh
