24-Port Fast Ethernet Switch Management Guide

CLI – Specify any interface, and then enter the threshold. The following
disables broadcast storm control for port 1, and then sets broadcast
suppression at 60 packets per second for port 2.
Configuring Port Mirroring
You can mirror traffic from any source
port to a target port for real-time
analysis. You can then attach a logic
analyzer or RMON probe to the target
port and study the traffic crossing the
source port in a completely unobtrusive
manner.
Command Usage
• Monitor port speed should match or exceed source port speed, otherwise
traffic may be dropped from the monitor port.
• All mirror sessions have to share the same destination port.
• When mirroring port traffic, the target port must be included in the same
VLAN as the source port.
