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
