This option obtains a list of the DLC services available for this communications adapter.
Before the system can use an installed data link control, it must be added to the system. This happens automatically at install time, and can be done manually by the operator when a DLC has been removed. Once added, the DLC is defined and configured into the system with a special file created as /dev/dlcname. This option adds the IEEE 802.3 Ethernet DLC with the special file name dlc8023. It also adds the Standard Ethernet DLC with the special file name /dev/dlcether.
This option allows the operator to 1) change or list the data link control attributes on a DLC that has already been added to the system, 2) change or list attributes for the IEEE 802.3 Ethernet DLC and 3) change or list attributes for the Standard Ethernet DLC.
Note: Data link controls that have active opens from protocol suite users such as SNA, OSI, or Netbios cannot change attributes until all active opens are closed.
This option allows the operator to remove a data link control device manager that was previously added to the system. This causes the specified DLC to be unconfigured and undefined from the system, the /dev/dlcname special file of the DLC is also deleted. This option also removes the Standard Ethernet DLC and removes the IEEE 802.3 Ethernet data link control.
Note: Data link controls that have active opens from protocol suite users such as SNA, OSI, or Netbios cannot be removed from the system until all active opens are closed.
Before the system can use an installed data link control, it must be added to the system. This happens automatically at install time, and can be done manually by the operator when a DLC has been removed. Once added, the DLC is defined and configured into the system with a special file created as /dev/dlcname. This option adds the Synchronous DLC (SDLC) with the special file name /dev/dlcsdlc.
This option allows the operator to 1) change or list the data link control attributes on a DLC that has already been added to the system and 2) change or list attributes for the Synchronous data link control. Data link controls that have active opens from users such as SNA Services cannot change attributes until all active opens are closed.
This option allows the operator to remove a data link control device manager that was previously added to the system. This causes the specified DLC to be unconfigured and undefined from the system and has its /dev/dlcname special file deleted. This option removes the Synchronous DLC (SDLC).
Note: Data link controls that have active opens from protocol suite users such as SNA cannot be removed from the system until all active opens are closed.
Before the system can use an installed data link control, it must be added to the system. This happens automatically at install time, and can be done manually by the operator when a DLC has been removed. Once added, the DLC is defined and configured into the system with a special file created as /dev/dlcname. This option adds the token-ring DLC with the special file name /dev/dlctoken.
This option allows the operator to change or list the data link control attributes on a DLC that has already been added to the system. Change or list attributes for the Token-Ring data link control.
Note: Data link controls that have active opens from protocol suite users such as SNA, OSI, or Netbios cannot change attributes until all active opens are closed.
This option allows the operator to remove a data link control device manager that was previously added to the system. This causes the specified DLC to be unconfigured and undefined from the system and has its /dev/dlcname special file deleted. This option also removes the Token-Ring DLC.
Note: Data link controls that have active opens from protocol suite users such as SNA, OSI, or Netbios cannot be removed from the system until all active opens are closed.
Before the system can use an installed data link control, it must be added to the system. This happens automatically at install time, and can be done manually by the operator when a DLC has been removed. Once added, the DLC is defined and configured into the system with a special file created as /dev/dlcfddi.
Select fddi to add the FDDI DLC with a special file name dlcfddi.
Select the desired DLC device from the list. Information about the device is presented in four columns: device class, device type, device subclass, and device description.
Allows the operator to change or list the data link control attributes on a DLC that has already been added to the system.
Select dlcfddi to change or list attributes for the FDDI data link control.
Note: Data link controls that have active opens from protocol suite users such as SNA, OSI, or Netbios cannot change attributes until all active opens are closed.
Select the desired DLC device from the list. Information about the device is presented in three columns: device name, device state, and device description.
Allows the operator to remove a data link control device manager that was previously added to the system. This causes the specified DLC to be unconfigured and undefined from the system and has its /dev/dlcname special file deleted. This option also removes the FDDI DLC.
Select dlcfddi to remove the FDDI data link control.
Note: Data link controls that have active opens from protocol suite users such as SNA, OSI, or Netbios cannot be removed from the system until all active opens are closed.
Before the system can use an installed data link control, it must be added to the system. This happens automatically at install time, and can be done manually by the operator when a DLC has been removed. Once added, the DLC is defined and configured into the system with a special file created as /dev/dlcname. This option adds the X.25 Qualified DLC (QLLC) with special file name /dev/dlcqllc.
This option allows the operator to change or list the data link control attributes on a DLC that has already been added to the system. Change or list attributes for the X.25 Qualified data link control.
Note: Data link controls that have active opens from protocol suite users such as SNA cannot change attributes until all active opens are closed.
This option allows the operator to remove a data link control device manager that was previously added to the system. This causes the specified DLC to be unconfigured and undefined from the system; the /dev/dlcname special file of the DLC is also deleted. This option also removes the X.25 Qualified DLC (QLLC).
Note: Data link controls that have active opens from protocol suite users such as SNA cannot be removed from the system until all active opens are closed.
This is the /dev name of the data link control device manager.
There is a queue between the device handler and the data link control that holds asynchronous event notifications such as receive data packets. This queue defaults to a depth of 32 entries which can be increased by the operator if error log entries indicate that the device handler is overrunning the DLC due to heavy system activity. This attribute should be increased in small increments as it directly affects system storage availability.
