Command Usage
You can mirror traffic from any source port to a destination port for real-time analysis. You can then attach a logic analyzer
or RMON probe to the destination port and study the traffic crossing the source port in a completely unobtrusive manner.
The destination port is set by specifying an Ethernet interface.
The mirror port and monitor port speeds should match, otherwise traffic may be dropped from the monitor port.
You can create multiple mirror sessions, but all sessions must share the same destination port. However, you should
avoid sending too much traffic to the destination port from multiple source ports.
