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.
