[c-nsp] Per session shaping

[Steve McCrory]

Are you aware of any techniques (expect DPI) that would allow us to
inspect a users traffic as their VPDN session passes through our network
via a series of tunnels?

Is it possible to terminate a user temporarily to apply some sort of QoS
before forwarding them onto to their final destination LNS?

Afternoon all,

 

I've been asked to look into the capabilities of the Cisco IOS feature
'Per-Session Shaping and Queuing' and I am looking for some expertise
from anyone who has utilized this feature.

 

I would like to know if it is possible to shape an SSS session that is
forwarded on to another LNS or is this feature specifically for shaping
subscriber sessions that terminate locally?

 

I tried configuring a service policy on the virtual-template that is
associated with the VPDN group for the incoming L2TP tunnel but this
appear to break everything and debugging radius identifies a 'nas-error'
as the cause:

 

*Apr 30 15:26:50.187: RADIUS:  Acct-Terminate-Cause[49]  6   nas-error
[9]

 

Cheers

 

Steven
