AW: [cisco-bba] Real life experience with NPE-G1 aggregation numbers

[Heiner Lante]

Hi,

could you please give me a idea, how much traffic you have on that boxes?

Our experience is, that the npe1g can handle up 
to 120 Mbit in/and 70 Mbit on the interface to 
the customers with up to 1500 sessions. With that 
traffic the cpu load goes up to 60 - 70%.

The higher the traffic, the higher the load of 
the boxes. If there is very less traffic, you can 
handle much more of l2tp sessions.

We have decided to add a new npe1g for every 100 
- 120 Mbit outboundtraffic per Box.

Regards Heiner
