Use the following procedure if you need to preserve the IP configuration that is associated with one network device and then move that configuration to another network device. You might perform this procedure prior to removing a network card from the system or when changing a network cable connection.
The procedure uses e1000g0 and nge0 as sample devices.
Before You Begin
Ensure that your role has the appropriate rights profile to perform this procedure. See Using Rights Profiles to Perform Network Configuration.
The following example shows that the IP configuration for e1000g0 is down and the configuration needs to be moved to nge0:
$ dladm show-phys LINK MEDIA STATE SPEED DUPLEX DEVICE net0 Ethernet down 0 unknown e1000g0 net1 Ethernet down 0 unknown e1000g1 net2 Ethernet up 1000 full nge0 net3 Ethernet down 0 unknown nge1
$ ipadm disable-if net0
$ dladm rename-link net0 oldnet0
This step makes oldnet0 as the link name of e1000g0.
For example, net2 is the link name of the nge0 device. Thus, you would type:
$ dladm rename-link net2 net0
$ ipadm enable-if -t net0
