Hi eandino,
-You can use the /usr/sbin/sys-unconfig command to undo a system’s configuration.
-You can use the /usr/sbin/sys-unconfig command to restore a system’s configuration to an as-manufactured state, ready to be
  reconfigured again. The system’s configuration includes a host name, NIS
  domain name, time zone, IP address, IP subnet mask, and root password.

 Advanced System Administration for the Solaris™ 9 Operating Environment
 -The sys-unconfig command does the following:
- Saves the current /etc/inet/hosts file information in the
  /etc/inet/hosts.saved file.
  If the current /etc/vfstab file contains Network File System (NFS)
  mount entries, it saves the /etc/vfstab file to the
  /etc/vfstab.orig file.
  Restores the default /etc/inet/hosts file.
  Removes the default host name in the /etc/hostname.xxn files for
  /etc/vfstab.orig file.
  Restores the default /etc/inet/hosts file.
  Removes the default host name in the /etc/hostname.xxn files for
  all configured interfaces.
  Removes the default domain name in the /etc/defaultdomain file.
  Restores the time zone to PST8PDT in the /etc/TIMEZONE file.
  Resets naming services to local files.
  Removes the entries for this host in the /etc/net/tic*/hosts file.
  Removes the /etc/inet/netmasks file.
  Removes the /etc/defaultrouter file for naming services.
  Removes the password set for the root user in the /etc/shadow file.
  Removes the /etc/.rootkey file for NIS+.
  Removes the /etc/resolv.conf file for DNS.

When the sys-unconfig command is finished, it performs a system
shutdown. The sys-unconfig command is a potentially dangerous utility
and can only be run by the root user.

Hope will solve your problem :-)

assume your system's name is "foo":

echo "foo.eri0" > /etc/hostname.eri0
echo "foo.eri1" > /etc/hostname.eri1

echo "<IP-eri0> foo.eri0" >> /etc/hosts
echo "<IP-eri1> foo.eri1" >> /etc/hosts

/etc/init.d/network stop
/etc/init.d/network start

If you are using subnets, you also have to provide appropriate entries in /etc/netmasks.

do a prtdiag command and see that you have 2 eri's listed
what does
ifconfig -a
What hardware is it?

Could possibly be bge interface, or if it is old hardware, could be something like hme

how i config the netmask? or verified that the network card is correct installed?
eandinoAuthor Commented:
how configure the net mask and for eri0 , eri1??
As already written, netmasks are configured via /etc/netmasks.
Nevertheless, There's still no eri1 device. Which model is your system? Do you have onboard interfaces only or do you also have a PCI card? In the latter case, which one?


eandinoAuthor Commented:
I have ha SUN SPARC, SunBlade150, Solaris 9. Two PCI card i have.

Initial when install the solaris 9 i have for default one interface eri0 configured.
But i need configure two interface for two diferent network.

Mking ha prtdiag:

                  okay  /pci@1f,0/network@c,1

                  okay  /pci@1f,0/pci@5/network

In instalation of solaris i have select (eri) to my interface!!!
¿How y config mi second interface?
¿my second interface it´s (ce)?
After inserting PCI-cards, did you do a reconfiguration boot? (boot -r)?
Alternatively, try a
Afterwards, what does
ifconfig -a
report now?
