Enabling or Disabling the ATM ARE Driver
By default, the router enables ATM ARE line services when you add the interface
to the configuration file. You can disable and reenable the interface without
moving physical cabling.
Setting the Maximum Transmission Unit (MTU)
By default, the MTU (or, maximum packet size) on the ATM ARE interface is
4608 octets. You can change the MTU to a value from 1 through 9188 octets.
Enabling or Disabling Data Path Notify
If the cable becomes disconnected from the ATM module, the router disables the
interface between the driver and the higher-level software (the data path interface)
after a period of time you specify with the Data Path Notify Timeout parameter.
