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.
• All mirror sessions must share the same destination port.
• When mirroring port traffic, the target port must be included in the same VLAN
as the source port
