Hi All,
I've got a couple of machines, one solaris10, one solaris11.
Each has two network interfaces.
One interface is used for management, and has a unique ipv4 address.
The second interface is used for production data. Only one of the
machines will be passing production traffic at a time, and the
production interfaces of the two machines will have the same ip address.
Obviously I can't have two machines with the same ip address live at the
same time. I need a way of downing & upping the interfaces as required,
and I need the state to be maintained across reboots.
I've tried "ipadm disable-if net1", but that fails, saying
"ipadm: persistent operation not supported for disable-if"
"ipadm disable-if -t net1" works, but as expected, a reboot enables the
interface.
In addition "ipadm enable-if -t net1" does not bring the interface back
up, I need to use "ifconfig net1 up" as well.
How do I do this?
Thanks.

Use ipadm delete-ip

ipadm create-addr -t -T static -a local=192.168.111.111/24 net1
u can also create it permanently and then down it:
ipadm down-addr net1/v4 (whatever the address obnject is)
which you can enable ipadm up-addr

ipadm up-addr net1/v4
Exactly this, thank you.
