A DLC must be added to the system prior to use. Each installed DLC is automatically added after installation and at each system restart. If a DLC has been removed without a subsequent restart, it can be re-added.

Notes:
- The SMIT fast path for an Ethernet device manager includes both Standard Ethernet and IEEE 802.3 Ethernet device managers.
- Details about command line options are provided in the command descriptions for mkdev, chdev, trace, trcstop, trcrpt, lsdev, lsattr, or rmdev in AIX 5L Version 5.2 Commands Reference.
- A DLC must be installed and added before you can list, show, change, or remove its attributes. An attribute change is only successful if there are no active opens against the target DLC. Before issuing the change action, the user might have to stop services such as SNA, OSI, or NetBIOS from using the DLC.
- Changing the receive-queue size directly affects system resources. Make this change only if the DLC is having receive-queue problems, such as sluggish performance or overflows between the DLC and its device handler.
- Exercise caution when enabling the monitor trace since it directly affects the performance of the DLCs and their associates.
- Removing a DLC is only successful if there are no active opens against the target DLC. Before issuing the remove action, the user may have to stop services such as SNA, OSI, or NetBIOS from using the DLC.
- These tasks are not available in Web-based System Manager Management Environment.
