I have 2 ports on sw1 that need to be mirrored to fa0/1 as well. I guess the only way to do it is to get monitor session 2... Correct?<br />

According to the Cisco TAC, you cannot have the same destination for different span session. So the below is not possible. Is that true?<br />
<br />
sw1:<br />
monitor session 1 source remote vlan 500<br />
monitor session 1 destination interface fa0/1<br />
monitor session 2 source fa0/10,fa0/20<br />
monitor session 2 destination interface fa0/1

I need to mirrors 3 ports, 2 on sw1 and the other one on sw2. The system that monitors the ports is on sw1. This is all Cisco Catalyst 3750.<br />
I have no problem to mirror the 2 ports on sw1 and send it to the port destination (fa0/1) where the monitor system is. I am not sure how to mirror the port on sw2 to sw1 (fa0/1). Any thoughts would be greatly appreciated.

mirror ports

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.

Switches / Hubs

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

Networking

Network analysis is the process of identifying and remediating the processes and systems within a network, including performance, connectivity and security. The process is performed through the use of tools developed for monitoring and analyzing network activity. Network problems that involve finding an optimal way of doing something are studied under the name combinatorial optimization. Examples include network flow, shortest path problem, transport problem, transshipment problem, location problem, matching problem, assignment problem, packing problem, routing problem, Critical Path Analysis and PERT (Program Evaluation & Review Technique).
