4.15 Mirror
Function name:
Mirror Configuration
Function description:
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.
Note:
When configuring the mirror function, you should avoid setting a port to be a sniffer
port and aggregated port at the same time. It will cause something wrong.
