How to Replace a Network Interface Card With Dynamic Reconfiguration
The following procedure applies only to systems that support dynamic reconfiguration(DR). It specifically refers to configuration steps after DR is completed. You no longer need toreconfigure network links after you complete the DR process. Instead, you just transfer the linkconfigurations of the removed NIC to the replacement NIC.
No NIC is inserted in slot 1. Assume that the datalink on slot 1 is net0, and the datalink on slot 2 is net1. You would specify that the datalink of the new NIC inherit the datalink configuration of the old NIC as follows: # dladm rename-link net1 net0; Complete the DR process by enabling the new NIC's resources so that they are available for. A Network Interface Card (NIC) is a computer hardware component that allows a computer to connect to a network. NICs may be used for both wired and wireless connections. A NIC is also known as a network interface controller (NIC), network interface controller card, expansion card, computer circuit board, network card, LAN card, network adapter.

The procedure does not describe the steps to perform DR itself. Consult your systemdocumentation for that information.
For an introduction to DR, see Chapter 2, Dynamically Configuring Devices in Managing Devices in Oracle Solaris 11.3.

Types of NIC Cards. NIC cards are of two types − Internal Network Cards. In internal networks cards, motherboard has a slot for the network card where it can be inserted. It requires network cables to provide network access. Internal network cards are of two types. Slot width; Riser-1B (2U riser) Slot 2: Processor 1: Full Height: Full Length: x16: Riser-1B (2U riser) Slot 3: Processor 1: Full Height: Full Length: x16: Riser-1A (low profile riser right) Slot 2: Processor 1: Low Profile: Half Length: x16: Riser-3A (low profile riser left) Slot 3: Processor 1: Low Profile: Half Length: x16.
Make sure that you complete the following steps first:
Ensure that your system supports DR.
Consult the appropriate manual that describes DR on your system.
To locate current documentation about DR on Sun servers from Oracle, search for 'dynamicreconfiguration' on https://docs.oracle.com/en/servers/.
For information about performing DR in the Oracle Solaris Cluster environment, see Oracle Solaris Cluster 4.3 System Administration Guide.
Become an administrator.
(Optional)Display information about the physical attributes of datalinks and their respective locationson the system.
For more information about the type of information that is displayed by the dladmshow-phys -L command, refer to the dladm(1M) man page.
Perform the DR process, as described in your system's documentation.
After you have installed the replacement NIC, proceed as follows, depending on thecircumstance that applies:
If you inserted the replacement NIC into the same slot as the old NIC, proceed to Step5.
With the new NIC using the location that was previously occupied by the old NIC, the new NICinherits the link name and the configuration of the old NIC.
If you inserted the replacement NIC into a different slot, and the new NIC needs to inheritthe datalink configuration of the removed NIC, rename the link as follows:
new-datalink
Refers to the datalink of the replacement NIC that is in a different slot from the locationfrom which the old NIC was removed.
old-datalink
Refers to the datalink name that is associated with the old NIC that was removed.
Note - In this scenario, the slot from which the old NIC was removed must remain empty.
For example, the NIC in slot 1 is removed, and then the new NIC is inserted in slot 2. No NICis inserted in slot 1. Assume that the datalink on slot 1 is net0, and thedatalink on slot 2 is net1. You would specify that the datalink of the new NICinherit the datalink configuration of the old NIC as follows:
Complete the DR process by enabling the new NIC's resources so that they are available foruse.
For example, you can use the cfgadm command to configure the NIC. Formore information see the cfgadm(1M) man page.
(Optional)Display link information.
You can use either the dladm show-phys command or the dladmshow-link command to display information about the datalinks.

Performing Dynamic Reconfiguration by Installing a New Network Card
Nic Slot 1000
The following example shows how a bge card with link namenet0 is replaced by an e1000g card. The link configurations ofnet0 are transferred from bge to e1000gafter e1000g is connected to the system.
Nic Slot 12
You would perform the DR-specific steps such as using the cfgadm command toremove the bge card and then install the e1000g card in itsplace. After the card is installed, the datalink of e1000g0 automatically assumesthe name net0 and inherits the link's configuration.
