3.5.21 Main Menu->Ports->Basic Port Config->Port Mirroring
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:
Set Port to be Monitored:
Set Traffic Direction:
Change Mirror Status:
Sets the monitoring port. All traffic is forwarded to this port.
Sets the monitored port. All traffic through this port is
forwarded to the monitoring port.
Sets the direction of monitored traffic, receiving(R),
transmission(T), or both direction(B).
Enables or disables the mirror status.
