Multiple SPAN (monitor) sessions on 6509 VSS

[dimensyssrl]

Hello.

I've this problem.

Our core switch is a double 6509e with sup2T configured as VSS.

We have configured 2 monitor sessions to two ntop (to graph network bw use); now we need another SPAN monitor session to a snort machine (ids), but limit is 2 span sessions...

How can we workaround this problem?

Is it possible to use RSPAN in some way?

I think that it's incredible that a powerful machine like Sup2T cannot do more than 2 sessions...

Thanks

Daniele

I have never tried but, possible to connect some switch to one of the ports available in your chassis and do the forwarding from that access switch?

If I do so, I only move the problem to another switch with same limit.

Yes, I can use two other switch with the two (original) span session, and I'll obtain 4 sessions, but it's not a practical operation... I'll have to maintain two new switches only for this...
