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 source and destination port speeds should match, otherwise traffic
may be dropped from the source port.
You can create only one port mirror session.
The source and destination ports have to be either both in the port
range 1-12 or both in the port range 13-24.
Example
The following example configures the switch to mirror all packets from
port 6 to port 11:
