Step 3
exit
Example:
Router(config-dhcp)# exit
Router(config)#
Exits DHCP pool configuration mode and
enters global configuration mode.
Step 4
chat-script script-name expect-send
Example:
Router(config)# chat-script Dialout ABORT ERROR
ABORT BUSY ““ “AT” OK “ATDT 5555102 T” TIMEOUT 45
CONNECT \c
Router(config)#
Configures a chat script for use in DDR to
give commands for dialing a modem and
for logging in to remote systems. The
defined script is used to place a call over a
modem connected to the PSTN.
Step 5
interface type number
Example:
Router(config)# interface Async 1
Router(config-if)#
Creates asynchronous interface and enters
configuration mode for the asynchronous
interface.
Configure the asynchronous interface. For
sample commands that you can use in
asynchronous interface configuration
mode, see the “Example” section on
page 113.
Step 6
exit
Example:
Router(config-if)# exit
Router(config)#
Exits interface configuration mode and
enters global configuration mode.
Step 7
interface type number
Example:
Router(config)# interface Dialer 3
Router(config-if)#
Creates dialer interface and enters
configuration mode for the dialer
interface.
Step 8
dialer watch-group group-number
Example:
Router(config-if)# dialer watch-group 1
Router(config-if)#
Specifies the group number for the dialer
watch list.
Step 9
exit
Example:
Router(config-if)# exit
Router(config)#
Exits interface configuration mode and
enters global configuration mode.
Step 10
ip nat inside source {list access-list-number} {interface
type number | pool name} [overload]
Example:
Router(config)# ip nat inside source list 101
interface Dialer 3 overload
Enables dynamic translation of addresses
on the inside interface.
