Defining the Data Path Notify Function
The data path notify function specifies whether the router disables the interface
between the driver and the higher-level software (the data path interface) when
you disconnect the cable from the ATM interface.
If you enable this function (the default), when you disconnect the cable from the
interface, the router disables the data path interface after a time you specify.
If you disable this function, the router does not disable the data path interface and
continues to send information to the higher-level software.
When you enable the data path notify function, you can also change how long you
want the ATM router to wait before disabling the data path interface. By default,
when the state of the physical interface changes from operational to
nonoperational, the router waits 1 second. However, you can set this timer to any
value from 0 to 3600 seconds.
Using the BCC
To disable the data path notify function, navigate to the atm prompt (for example,
box; atm/11/1
) and enter:
dp-notify disabled
For example, the following command disables the data path notify function on the
ATM interface:
atm/11/1#
dp-notify disabled
atm/11/1#
To reenable the data path notify function, navigate to the atm prompt and enter:
dp-notify enabled
To change the data path notify timeout value, navigate to the atm prompt and
enter:
dp-notify-timeout
<integer>
integer
is the amount of time (in seconds) that the router can wait before the data
path notify function activates.
