The [Solaris 10] patches to be able to use IP Instances with the Cassini ethernet interface, known as ce, are available on sunsolve.sun.com for Solaris 10 users with a maintenance contract or subscription. (This is for Solaris 10 8/07, or a prior update patched to that level. These patches are included in Solaris 10 5/08, and also in patch clusters or bundles delivered at or around the same time, and since then.)
The SPARC patches are:
- 137042-01 SunOS 5.10: zoneadmd patch
- 118777-12 SunOS 5.10: Sun GigaSwift Ethernet 1.0 driver patch
The x86 patches are:
- 137043-01 SunOS 5.10_x86: zoneadmd patch
- 118778-11 SunOS 5.10_x86: Sun GigaSwift Ethernet 1.0 driver patch
I have not been able to try out the released patches myself, yet.
