Asynchronous Interface Backup DDR Configuration Example
The following is an example of one asynchronous interface configuration on a Cisco AS2511-RJ access
server that is used in an asynchronous backup DDR scenario:
interface async 1
description ASYNC LINE 5293731 TO HIGHWAY
encapsulation ppp
async default routing
async mode dedicated
dialer in-band
dialer map ip 192.168.10.2 name Router2 broadcast
dialer-group 1
ppp authentication chap
Passive Header Compression and Default Address Example
The following configuration shows interface and line configuration. The interface is configured with
access lists, passive header compression, and a default address. The line is configured for TACACS
authentication.
interface async 1
ip access-group 1 in
ip access-group 1 out
ip tcp header-compression passive
async default ip address 172.31.176.201
line 1
login tacacs
location 457-5xxx
exec-timeout 20 0
password XXXXXXXX
session-timeout 20
stopbits 1
High-Density Dial-In Solution Using Autoselect and EXEC Control Example
The following example configures a Cisco AS5800 access server, which is used as a high-density dial-in
solution:
line 1/2/00 1/9/71
session-timeout 30
exec-timeout 30 0
absolute-timeout 240
autoselect during-login
autoselect ppp
