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.
• 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.
• When mirroring traffic from a port, 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.
