Command Usage
• You can mirror traffic 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.
• Set the destination port by specifying an Ethernet interface with the interface
configuration command, and then use the port monitor command to specify
the source of the traffic to mirror.
