Multiple Network Card Status Script

[nongdanviet]

I have multiple Sun Solaris 8 systems running multiple network cards. (Mix of quad and gig cards.)



What I would like to do is create a monitor script to ensure high availability of these cards.



Has anyone ever had a situation like this?



I was thinking of using the ping command, but am not sure if that is the most efficient way to go.



Any thoughts are appreciated.



Thanks.
