Configure virtual ip - second ip

Hello Group,

Could you please help me with the procedure to configure a virtual ip (second ip) under the same interface in Solaris 11.

Thanks in advance !

Working With IP Interfaces - Connecting Systems Using Fixed Network Configuration in Oracle Solaris 11.1

in short:

# dladm create-vnic -l net0 vnic0
# ipadm create-ip vnic0
# ipadm create-addr -T static -a 192.168.0.80 vnic0/v4

While vnics are definitely cool, it is not required to create one if you don't want a new virtual "physical interface" to be created but just need a virtual IP on the same interface which is what I believe the OP asked.
This single line would be sufficient:

# ipadm create-addr -T static -a 192.168.0.80/24 net0/virtual1
