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.
Example
The following example configures the switch to mirror all packets from
port 6 to 11:
Console(config)#interface ethernet 1/11
Console(config-if)#port monitor ethernet 1/6 both
Console(config-if)#
