MGS3700-12C User’s Guide

RMirror lets you redirect data flows that you monitor on a source switch to a 
different destination switch, which allows a centralized network analyzer or probe 
to capture packets for an entire LAN. Because traffic flows are not directly copied 
to monitor port, but reflected on a designed RMirror VLAN. RMirror make distance 
remote source switch possible that port-mirroring traffic can be monitored by 
different switches supported RMirror feature.

RMirror feature supported:

• Remote mirroring of ingress and egress traffic.
• Control packets mirrored.
• Two types of source switch for different requirements.
• CLI, WEB and MIB interface of configuration
• RMirror VLAN traffic priority setup

Before you start setting RMirror VLAN, you should know all the roles of switch in the 
network.

• Source  switch: 

The port traffic mirrored on RMirror VLAN.

• Intermediate switch: 

Forwarding traffic from source switch to destination switch. The intermediate 

switch can not only be our switch device, other supplier switch device is suitable 

for use.

• Destination switch: 

Monitor traffic from source switch. The destination switch can not only be our 

switch device, other supplier switch device is suitable for use.
