I have two 6509 switches trunked together.
6509 #1 is downstairs, 6509 #2 is up stairs.
There is also a router connected to the 6509 upstairs that connects our remote sites to the main site.
I have a 3550 switch downstairs that is used in a training room, also trunked to the 6509 upstairs.
We have a network monitoring device that is going to sit upstairs on the 6509 #2.
We would like to set up a session that will capture all traffic on the internal network.
If I create an RSPAN session on the switches to capture all vlans that I want to monitor and the destination port is on the upstairs 6509, will I also be able to capture the traffic on the upstairs 6509?
The source vlans are on all switches and I am unclear when configuring the RSPAN session, if the destination port on the upstairs 6509 will also capture traffic on the VLAN ports on the same switch.
For example, if I configure the RSPAN to capture (source VLANs) VLAN 2-20 and the destination port is on the upstairs 6509, will I also capture the traffic on the ports that are members of VLANs 2-20 on the upstairs 6509 where the destination port resides?
Will I also capture the traffic inbound from the router in those VLANS on the upstars switch?
