If you perform the dialer enable-circular command or its undo form on a 
non-dial interface, do the same on the interface to recover it.
Related command:
Example
# Enable C-DCC on interface Serial 2/0.

Parameter
interval: Traffic statistics interval, in the range 1 to 1500 seconds.
Description
Use the dialer flow-interval command to configure the traffic statistics interval 
for DCC.
Use the undo dialer flow-interval command to restore the default.
By default, the traffic statistics interval for DCC is 20 seconds.
This command is only useful for traffic-triggered dial in DCC. For example, when 
using traffic-triggered MP link bundling with DCC, you may need to configure 
DCC to send traffic statistics about dialup links at certain intervals to MP.

Example
# Set traffic statistics interval to three seconds for DCC.
