Port Mirroring Configuration
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. This is useful for network monitoring and troubleshooting purposes. To view the
Port
Mirroring
window, click
Port Mirroring

NOTE:
The user cannot mirror a fast port onto a slower port. For example,
if attempting to mirror the traffic from a 100 Mbps port onto a 10 Mbps
port, this can cause throughput problems. The port from which frames are
being copied should always support an equal or lower speed than the port
which is sending the copies. In addition, the target port for the mirroring
cannot be a member of a trunk group. Please note a target port and a
source port cannot be the same port.
