How to generate LABP Disconnect on a router

[admin_2]

For technical training we need a to force a "clean" LAPB Disconnect. How do we force such normal clean on a Cisco 2611 with a X.25 connection to a X.25 Switch ?

With "int s0/0, shutdown", the router simply put the RTS Signal OFF. And I didn't found any clear command that force a LABP Disconnect message to be send.

With an X25 interface, the best that you

can do is to clear the X25 interface or VC

which will cause a RESATART to be sent at

the X25 layer. There isn't a way to generate

any LAPB DISCONNECT frame via the exec

CLI.
