Using Diagnosis
The Moxa switch provides three important tools for administrators to diagnose network systems.
Mirror Port
The Mirror Port function can be used to monitor data being transmitted through a specific port. This is done by
setting up another port (the mirror port) to receive the same data being transmitted from, or both to and from, the
port under observation. Using a mirror port allows the network administrator to sniff the observed port to keep tabs
on network activity.
Please note that two types of mirror port settings are available, depending on the specific model of switch. In Type
1, the switches support multi-to-one and one-to-one mirror function. In Type 2, the switches support only
one-to-one mirror function.
