Asynchronous Line Backup DDR Configuration Example
The following example configures one asynchronous line on a Cisco AS2511-RJ access server that is
used in an asynchronous backup DDR scenario:
line 1
modem InOut
speed 115200
transport input all
flowcontrol hardware
Line AUX Configuration Example
In the following example, the asynchronous interface corresponds to the AUX port. Use the show line
command to determine which asynchronous interface corresponds to the AUX port. The IP address on
the AUX ports of both routers are in the same subnet

Rotary Group Examples
The following example establishes a rotary group consisting of virtual terminal lines 2 through 4 and
defines a password on those lines. By using Telnet to connect to TCP port 3001, the user gets the next
free line in the rotary group. The user need not remember the range of line numbers associated with the
password.
