Hi,


in my Campus Lan, i've one core switch (4506) and several acess swicth (2950)


On an access switch i create a monitor sesion to get trafic for a particular port. Works fine.


On another switch (not in the same stack), i create another monitor session (with the same number) to see trafic for a particulor poirt on this switch. Works fine BUT i also see trafic from monitor on the other span session ?


I don't understand why. I don't use rspan.


Any idea ?


Regards

If its a trunked environment you could see some of the same traffic.

Are you sure it is not just the broadcast traffic you are seeing? If so, that would be normal.
