, allows the user to set 

each port (1 through 26) as a source or destination port. A port can be set 
to have one or more destination ports. For example, port 1 can be set as a 
source port with three destinations, ports 2, 3, and 4. Traffic from port 1 is 
then automatically redirected to ports 2, 3, and 4. Port 1 can also serve as 
a destination port for other ports.

The port redirect function is extremely useful for troubleshooting 
purposes, as it allows traffic to be sent to a particular port(s) where, with 
the use of an analyzer or RMON probe, all current traffic from the source 
port(s) can be examined.

To access the Port Redirect Function screen from the Device Specific 
Configuration Menu screen, use the arrow keys to highlight the PORT 
REDIRECT FUNCTION menu item and press ENTER. The Port 
Redirect Function

 screen displays.

The Port Redirect Function screen may not be available

Although all traffic from the source port (including, if desired, 
errored frames) is sent to the destination port, normal switching 
is still performed for all frames on the source port.
