To return a line that has been placed into dedicated asynchronous network mode to interactive mode, thereby enabling the slip and ppp EXEC commands, use the async mode interactive command in interface configuration mode. To prevent users from implementing Serial Line Internet Protocol (SLIP) and PPP at the EXEC level, use the no form of this command.

async mode interactive

no async mode interactive

Syntax Description

This command has no arguments or keywords.

Command Default

Asynchronous mode is disabled.

Command History

Release Modification
10.0 This command was introduced.

Usage Guidelines

Interactive mode enables the slip and ppp EXEC commands. In dedicated mode, there is no user EXEC level. The user does not enter any commands, and a connection is automatically established when the user logs in, according to the configuration.


The following example places asynchronous interface 6 into interactive asynchronous mode:

interface async 6
 async default ip address
 async mode interactive
 ip unnumbered ethernet 0
