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: | 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. |
