CLI – Specify any interface, and then enter the threshold. The following
sets broadcast suppression at 600 packets per second.
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.
Command Attributes
• Mirror Sessions – Displays a list of current mirror sessions.
• Source Port – The port whose traffic will be monitored.
