Hey all,
I have a few 4500's running 2.6 that have multiple NIC's. All of the NICs are on a flat class B network. Veritas VCS is being added to the boxes and that product requires that it have exclusive control over entire subnets. Therefore I need to carve off a new class C on two of the interfaces, but don't want to change the masks on the others. I can change the masks and broadcast settings of two of the interfaces on the fly with ifconfig commands, but a reboot will reset them to the default class B settings. My question is, what is the correct way to change the settings on these interfaces on Solaris 2.6. I don't know of a file that has per-interface settings (like Linux does). I can always make a custom RC script, but that seems a little inelegant. Any advice on the proper way to do this?

Well, you can put the commands in a shell script (sh), and put the script in /etc/rc2.d, name it soemthing like S42setnic (or other names, just make sure that the filename is starting with an upper case "S", the file permissions can be the same as the other startup script in the same dir).
Make sure that you put, the following line as the first line of your script:
#!/sbin/sh
# put all you ifconfig commands here.
