13-4 Mirroring
You can mirror traffic from any source port to a target port for real-time analysis. You can then
attach a logic analyzer or RMON probe to the target port and study the traffic crossing the
source port in a completely unobtrusive manner.
Mirror Configuration is used to monitor the traffic of the network. For example, assume that
Port A and Port B are Monitoring Port and Monitored Port respectively; the traffic received by
Port B will be copied to Port A for monitoring.
