24-port NWay Ethernet Switch User’s Guide
Web-Based Network Management 101
The Switch allows you to copy frames transmitted and received on a port and redirect the copies to another port. You can
attach a monitoring device to the mirrored port, such as a sniffer or an RMON probe, to view details about the packets
passing through the first port.
To configure a mirror port, select Enabled from the Port mirroring in pull-down list. In the next field, select the
Source Port from where you want to copy frames. In the last field, select the Target Port, which receives the copies
from the source port. This is the port where you will connect a monitoring/troubleshooting device such as a sniffer or an
RMON probe. Click Apply to let the changes take effect.
Note: You cannot mirror a fast port onto a slower port. For example, if you try to mirror the traffic from a 100 Mbps
port onto a 10 Mbps port, this can cause throughput problems. The port you are copying frames from should
always support an equal or lower speed than the port to which you are sending the copies. Also, the target
port for the mirroring cannot be a member of a trunk group. Please note a target port and a source port can
not be the same port.
