Hi all,
I have setup RSPAN between two 2960, which are connected through 6509 VSS. I configured two remote-span VLANs on all three switches and setup soure and destination. The source interface is a trunk port itself, which is connected to our WAN.
After I finished setting up the monitoring session, eveything seems to work fine for a couple of seconds. That is, I can capture the traffic on the destination interface and feed it into ntop. However, after a couple of seconds, pings to the remote sites on the WAN are starting to get lost and finally no connection does work anymore until I shut down the monitoring session, e.g. by removing the destination interface from the remote session.
I have a gutt feeling that this is somehow arp-related, but I can't pinpoint it.
Any idea anyone?
Thanks.
