Starting the SunATM Software for the First Time

This section will describe how to use the drvconfig command and the S00sunatm run control script to start up the SunATM software and load the driver module to the system. When you reboot the system, these commands will be run and start the software correctly.

Plumbing and Unplumbing Individual ATM Interfaces

The atmifconfig utility allows interfaces to be added, modified, or removed without rebooting the system by setting up and tearing down the streams necessary to use an ATM device. This setting up and tearing down of streams is referred to as plumbing and unplumbing.

The two required parameters for the utility are an interface name and plumbing instructions. If an interface is being set up for native ATM applications (no TCP/IP) or for Classical IP, the interface name should have the format baN, where N is the instance number. For LAN Emulation instances, the interface should have the format laneN, where N is the LAN Emulation instance number.

The second required parameter is the plumbing instruction. There are four possible values: plumb, unplumb, plumb-all, and unplumb-all. The plumb and unplumb options will set up or tear down the specified interface. The plumb-all and unplumb-all options will set up or tear down all ATM instances on the specified physical interface. In this case, the interface parameter must be a baN value, since this specifies the physical interface name. This will set up or tear down all the ATM instances on this physical interface, including up to 16 LAN Emulation instances and the Classical IP instance.
