[c-nsp] Weird L2TP Problem

[Dermot Williams]

Hi List,

 

We've a 7301 running IOS 12.3(4r)T4 acting as an LNS. We've never had
any major problems with it but today it stopped terminating sessions.
When I enabled terminal monitoring (with no additional debug) I started
getting messages like this one:

 

%L2TP-3-ILLEGAL: _____:_____: ERROR: [l2tp_session_get_l2x_cfg::241]
-traceback- (snip)

%L2TP-3-ILLEGAL: _____:_____: ERROR: no config -traceback- (snip)

 

I tried clearing all L2TP tunnels and they immediately came back up with
no sessions. Only a reload worked as far as letting subscribers back on
normally.

 

Does anyone have any idea what these errors mean?

 

Thanks,

 

Dermot Williams
