Port mirroring allows one port on the ES3000 to see all of the packets passing through any other port
on the switch. Usually, a network analyzer is attached to the monitoring port so the network
administrator can debug problems with the monitored port.
The ES3000 has two gigabit Ethernet ports, ports 25 and 26. A 10/100BaseT port would not be able
to keep up with the packet flow on a gigabit port. Only another gigabit port may monitor a gigabit
port. Any port on the ES3000 may be used to monitor ports 1 through 24, the 10/100BaseT ports.
Use the Port Mirroring menu to designate a port for monitoring traffic from a listed port or a single
VLAN on the switch. The switch monitors network activity by copying traffic from the specified
monitoring sources to the designated monitoring port. There are four commands within the menu:
Set Monitoring Port: Sets the monitoring port. All traffic is forwarded to this port.
Set Port to be Monitored: Sets the monitored port. All traffic through this port is
forwarded to the monitoring port.
Set Traffic Direction: Sets the direction of monitored traffic, receiving(R),
transmission(T), or both direction(B).
Change Mirror Status: Enables or disables the mirror status.
