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 4-127
