Span Monitor clients over layer3 link

[chpmotry]

Hi guys. 

I have two units with separate networks that are connected to the core switch through static route(I have attached the network schematic image below ). I want to monitor the traffic of my clients who are in different units in a span server behind the core switch. My switches model are 2960x and core switch model is c4507 .

 

What should I do so that the traffic of the clients goes to the span server?

ESXi dVS can support ERspan, which you could then send to the C4507, which also supports ERspan.

You are pretty limited without some 2960<>4507 L2 links where you could use rspan.

With L3 boundaries, you are likely going to need ERspan capable devices (this excludes 2960s).
