atmadmin and the SunATM Configuration Files in the /etc/opt/SUNWconn/atm directory

The atmadmin program first attempts to read the current configuration information from the /etc/opt/SUNWconn/atm/atmconfig, /etc/opt/SUNWconn/atm/aarconfig, and /etc/opt/SUNWconn/atm/laneconfig files. If no configuration information is found, or if the files do not exist, the default values listed in Table 2-2 are applied to the installed interfaces.

When saving configuration information, atmadmin overwrites the existing SunATM configuration files in the /etc/opt/SUNWconn/atm directory. Therefore, any comments or other changes you manually made to the files will be lost.
