DESCRIPTION:

How to add a second ethernet card to a Solaris system that was installed
with only one ethernet card. 


SOLUTION:

Things to do when adding a second ethernet card.

1) Make sure the IRQ and I/O address of the ethernet card does not clash
   with any other card on the machine. 

2) Choose name and internet address for the new card you are going to
   add. 

3) Create a file /etc/hostname. where
   I -> Name of interface. (ex, SMC, el, elx, iee etc.)
   N -> Number of card, if the card with the same
       interface is already present.

Here are two examples to illustrate,

If you have an SMC card and are now adding a Intel EtherExpress card as
your second interface.  The filename will be /etc/hostname.iee0

If you have an SMC card and are now adding another SMC as your second
interface the filename will be /etc/hostname.smc1

4) Edit the file and enter the name of your second interface in the
   file.  This file will contain the name you have chosen for the second
   interface. 

5) Edit /etc/hosts file and make a   entry for
   the second interface. 

6) Shutdown the system and plug in the network card.

7) Reboot the system with a b -r. This will reconfigure your system.
