RSPAN from multiple sources to multiple destinations

[5d-swan]

Hi

I would like to be able to monitor multiple RSPAN sessions from multiple switches. (for example i have three VLANs I want to monitor on three switches all to have a destination of three Ethernet interfaces) Ideally I would like all the RSPAN sessions to be monitored by 3 ports.

Do I need to have an RSPAN VLAN for each real VLAN I am monitoring and can that be replicated to multiple ports?

Thanks in advance!

As far as if you can have multiple destination port on a single session the answer is yes. This is assuming that you have 3750. I believe that most of the otehr switches have the same limitation but you should check the configuration guide for that particular switch. Yuo can also use multiple vlan as a SPAN source.

Is it possible to have multiple switches 'feeding' into the RSPAN VLAN though? Or do I need to have an RSPAN session for each switch?
