To place a line into dedicated asynchronous mode using Serial Line Internet Protocol (SLIP) or PPP encapsulation, use the async mode dedicatedcommand in interface configuration mode. To return the line to interactive mode, use the no form of this command.

Command History

Usage Guidelines

With dedicated asynchronous network mode, the interface will use either SLIP or PPP encapsulation, depending on which encapsulation method is configured for the interface. An EXEC prompt does not appear, and the router is not available for normal interactive use.

If you configure a line for dedicated mode, you will not be able to use the async dynamic address command because there is no user prompt.

Examples

The following example assigns an IP address to an asynchronous line and places the line into network mode. Setting the stop bits to 1 enhances performance.

interface async 4
 async default ip address 172.31.7.51
 async mode dedicated
 encapsulation slip
line 20
 location remote computer
 stopbits 1
 speed 115200
