Hello,
One of our clients wants to implement the following topology:
+----------+C
|Cisco 2921|<---------+
+----------+ |
|B
+----------+ A+------------+D
| Internal |---->| Cisco 2960 |----> ISP
+----------+ +------------+
Normal traffic flows from port A to port D.
The goal is to use the router as a netflow analyzer, using SPAN to mirror the traffic on port A to port B.
On port B we can see output rate, but on port C (on the router) we see no input rate at all.
Any ideas?
Regards,
Shahar.
