62 SunATM 3U CompactPCI Adapter Installation and User’s Guide • February 2001
Starting the SunATM Software for theFirst Time
This section will describe how to use the drvconfig command and the S00sunatm
run control script to start up the SunATMsoftware 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 IndividualATM 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 ATMdevice. 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 ATMapplications (no TCP/IP)
or for Classical IP,the interface name should have the format baN, where Nis the
instancenumber. For LAN Emulation instances, the interface should have the format
laneN, where Nis 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 ATMinstances on the specified
physical interface. In this case, the interface parameter must be a baNvalue, since
this specifies the physical interface name. This will set up or tear down all the ATM
instanceson this physical interface, including up to 16 LAN Emulation instances and
the Classical IP instance.
