Mirroring - ZyXEL Communications XGS3600 Series Manual

3-17 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 to monitor the traffic of the network. For example, we assume that Port
A and Port B are Monitoring Port and Monitored Port respectively, thus, the traffic received by
Port B will be copied to Port A for monitoring.
