Track vpdn tunnels

[v.matiakis]

Hi there, I have several problems with vpdn sessions suddenly dropping. It is an LAC-LNS scenario. I was wondering, is there a way to track sessions when they drop and have users? thanx in advance!

I would look at 'vpdn logging tunnel-drop' and friends

What do you mean by look at 'vpdn logging tunnel-drops'??

Please let me know

In a global configuration mode you configure vpdn loggging

vpdn logging tunnel-drop

I want to see syslog messages when vpdn user connects and when disconnects

I did

vpdn enable

vpdn logging

vpdn logging local

vpdn logging user

vpdn logging tunnel-drop

!        

vpdn-group 1

accept-dialin

  protocol l2tp

  virtual-template 3

terminate-from hostname splac

local name Ank

l2tp tunnel password 4D5A1C170B

and I see only when disconnect
