Explanation:
A: To rename the bge0 link to mgmt0, enter the following command:
# dladm rename-link bge0 mgmt0

E: Consider that the bge0 device, whose link was named mgmt0 as shown in the previous
example, needs to be replaced with a ce0 device because of a hardware failure. The bge0 NIC is
physically removed, and replaced with a new ce0 NIC. To associate the newly added ce0 device
with the mgmt0 configuration previously associated with bge0, enter the following command:
# dladm rename-link ce0 mgmt0
Note: How to Rename a Datalink
Use this procedure if you want to change a datalink name to a customized name. For example,
some of the datalinks in upgraded system might have retained legacy hardware-based names and
you want to change these names to generic ones.
Note: dladm rename-link [-R root-dir] link new-link
Rename link to new-link. This is used to give a link a meaningful name, or to associate existing
link configuration such as link properties of a removed device with a new device.
