The following tables list the different datalink configuration tasks that you can perform by using the dladm command. The tables also links you to the step-by-step procedures to complete the tasks.

Table 8-1 Performing Basic Datalink Configuration (Task Map)

Task	Description	For Instructions
Rename a datalink.	Customizes a datalink name instead of using the hardware–based name.	How to Rename a Datalink
Display physical attributes of a datalink.	Lists physical information that underly a datalink, including type of media, associated device instance, and other information.	How to Display Information About Physical Attributes of Datalinks
Display state of datalinks.	Lists information about the status of datalinks.	How to Display Datalink Information
Remove a datalink.	Removes a link configuration that is associated with a NIC no longer in use.	How to Delete a Datalink

Table 8-2 Setting Datalink Properties (Task Map)

Task	Description	For Instructions
Modify the MTU size.	Increases the MTU size of packet transmission to handle Jumbo frames.	How to Enable Support for Jumbo Frames
Modify the link speed.	Switches off higher link speed and advertises only the lower link speed to allow communications with an older system.	How to Change Link Speed Parameters
Display information about link properties.	Lists link properties and their current configuration; lists Ethernet parameter settings.	How to Obtain Status Information About Datalink Properties
Configure the driver to use DMA binding.	Sets threshold that causes the driver to switch between DMA binding and `bcopy` function during transmission.	How to Set the `e1000g` Driver to Use Direct Memory Access Binding
Set interrupt rates.	Manually defines rates at which interrupts are delivered by the driver instead of the rate being defined automatically.	How to Manually Set the Interrupt Rate
Replace a network interface card (NIC).	Changes a NIC in a system during dynamic reconfiguration (DR).	How to Replace a Network Interface Card With Dynamic Reconfiguration
Set per-link `autopush` properties.	Configure STREAMS module to be pushed on top of a datalink.	How to Set STREAMS Modules on Datalinks
