How to Configure Other Asynchronous Line and Interface
Features
This section describes the following asynchronous line and interface configurations:
Configuring the Auxiliary (AUX) Port
Establishing and Controlling the EXEC Process
Enabling Routing on Asynchronous Interfaces
Configuring Dedicated or Interactive PPP and SLIP Sessions
Conserving Network Addresses
Using Advanced Addressing Methods for Remote Devices
Optimizing Available Bandwidth
Configuring the Auxiliary (AUX) Port
The AUX (auxiliary) port is typically configured as an asynchronous serial interface on routers without
built-in asynchronous interfaces. To configure the AUX port as an asynchronous interface, configure it
first as an auxiliary line with the line aux 1 global configuration command.
The AUX port sends a data terminal ready (DTR) signal only when a Telnet connection is established.
The auxiliary port does not use request to send/clear to send (RTS/CTS) handshaking for flow control.
To understand the differences between standard asynchronous interfaces and AUX ports configured as
an asynchronous interface, refer to Table 4. To enable the auxiliary port, use the following command in
global configuration mode:
Command Purpose
Router(config)# line aux
line-number
Enables the auxiliary serial DTE port.
