IP, IPX, and AppleTalk Dial-Up Environments 5-19
Dial-In Configuration Examples
Security Configuration
The following example uses a TACACS+ security database. No security is configured on the console
port, which is physically secure. This configuration uses default configuration parameters. ARA
authentication permits guests to log in and access network resources.
aaa new-model
aaa authentication login default tacacs+
aaa authentication arap default guest tacacs+
enable secret 5 $17dd$VTNs4.BAfQMUU0Lrvw6570

arap authentication default
login authentication default
Protocol Configuration
The following example enables an ARA client to dial in with AppleTalk over PPP (ATCP). ARA
clients dial in and automatically have an ARA session started (after the security dialog appears). In
this example, IP is enabled on Ethernet interface 0 to allow basic IP connectivity.

Combined IP–PPP, IPX–PPP, and ARA Example
The following configuration example enables remote clients to dial in to IP, IPX, AppleTalk
networks and permits users to log in and connect to the EXEC facility.
Modem and Line Configuration
The following example configures lines 1 through 16 on a Cisco 2511 access server for modem
control. It assumes lines 1 through 8 have Hayes Optima modems. (The Cisco IOS software can
configure a Hayes Optima modem automatically.)
This configuration assumes that lines 9 through 16 have Practical Peripherals PC28800SA V.42bis
modems. If you issue the modem autoconfigure discovery line configuration command, the
Cisco IOS software attempts to identify the modem string that initializes the Practical Peripherals
