The following scenario is given :
P1----------------- --------------------P1
| | | |
| Switch 1 |------------------------------------| Switch 2 |
| | Trunk | |
P2----------------- ----------------------
Two Catalyst 3750 Switches connected with a trunk link.
On Switch 1 Port 2 (P2) a network analyzer is connected (single port)
Is there a way to SPAN traffic from port P1 on Switch 1 AND traffic
from port P1 on Switch 2 to this port (Port 2) ?
Any techniques to achieve this goal can be used (local SPAN, RSPAN...).

Hi
From the manual:
The switch does not support a combination of local SPAN and RSPAN in a single session. That is, an RSPAN source session cannot have a local destination port, an RSPAN destination session cannot have a local source port, and an RSPAN destination session and an RSPAN source session that are using the same RSPAN VLAN cannot run on the same switch stack.
So- RSPAN the Switch 2 port accross the link to the port X on switch 1.
SPAN the local Switch 1 port to porty Y on switch 1.
Don't allow ingress from the analyser, and attach both ports to it via a hub.
Or have two analysers.
Or - have a third switch as the destination RSPAN session for the ports from switch 1 and switch 2 (i.e. not mixing local SPAN and RSPAN).
