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
This task enables PPP on VTY lines on a global basis on t he rout er. To
configure PPP on a per-VTY basis, use th translate command.
Monitor and
Maintain MLP,
MMP, and VPDN
Virtual Interfaces
To monitor and maintain virtual interfaces, you can perform any of
these tasks:
zDisplay MLP and MMP bundle information.
show ppp multilink
z Display information about the active L2F tunnels and the L2F
message identifiers.
show vpdn
zDisplay the status of the stack gro up members.
show sgbp
zDisplay the current seed bid value.
show sgbp queries
