Enable PPP on VTY Lines for Asynchronous Access over ISDN

You can configure a router to support asynchronous access over ISDN by globally enabling PPP on VTY lines. PPP is typically enabled on synchronous or asynchronous serial interfaces; however, the Cisco IOS software permits you to configure PPP on VTY lines. This con- figures the VTY line to support asynchronous access over ISDN from an ISDN terminal to a VTY session on the router.

In global configuration mode, enable asynchronous protocol features on all the router's VTY lines:

vty-async

Monitor and

MMP, and VPDN

Virtual Interfaces

This task enables PPP on VTY lines on a global basis on the router. To configure PPP on a per-VTY basis, use th translate command.

To monitor and maintain virtual interfaces, you can perform any of these tasks:

zDisplay MLP and MMP bundle information. show ppp multilink

zDisplay information about the active L2F tunnels and the L2F message identifiers.

show vpdn

zDisplay the status of the stack group members. show sgbp

zDisplay the current seed bid value. show sgbp queries
