Interface Configuration (Ethernet, destination port)
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.
