SPAN Configuration
w
With SPAN, you can analyze the communications between ports by copying a
frame from one port to another port connected with a network analysis device or
RMON analyzer. The SPAN mirrors all the packets sent/received at a port to a
physical port for analysis.
For example, all the frames on the GigabitEhternet port 5 are mirrored to the
GigabitEhternet port 10, as shown in Figure 18-1. Although the network
d to port 10 is not directly connected to port 5, it can receive
all the frames from port 5.

The SPAN allows you to monitor all the frames incoming/outgoing the source
port, including the route input frames.
The SPAN does not affect the normal packet switching of the switch. Instead, it
copies the frames incoming/outgoing the source port to the destination port.
However, the frames may be discarded on an overflowed destination port, for
example,
when an 100Mbps port monitors an 1000Mbps port.
