Command Mode
Interface Configuration (Ethernet, destination port)
Command Usage
• Traffic can be mirrored from any source port to a destination port for
real-time analysis. A logic analyzer or RMON probe can then be
attached to the destination port to 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.
• Multiple mirror sessions can be created, but all sessions must share the
same destination port. However, avoid sending too much traffic to the
destination port from multiple source ports.
Example
The following example configures the ECN330-switch to mirror all packets from
port 6 to port 11:
7.11.2 show port monitor
This command displays mirror information.
Syntax

interface - ethernet <unit>/<port> (source port)
• unit - ECN330-switch (unit 1).
• port - Physical port number on the ECN330.
Console(config)#interface ethernet 1/11
