How do I display an interface status in solaris 10?

$ /usr/bin/netstat -i

Ipkts = input packet count
If this figure increases each time a client tries to boot but the Opkts (output packet count) stays steady, then this could indicate that the server is seeing the boot request packets from the client but does not know to respond to them.
This may be caused by an incorrect address in /etc/hosts, /etc/inet/ipnodes or /etc/ethers.

On the other hand, if the Ipkts (input packet count) is stable over a period of time, then the server does not see the packets at all. This may indicate a hardware failure.
