3.8.3 Port Mirroring
Port mirroring refers to the process of copying the packets received or sent by the specified
port to the destination port for packet analysis and monitoring. Generally, a destination port is
connected to a data detect device, which users can use to analyze the mirrored packets for
monitoring and troubleshooting the network, shown as the following figure:
Configuration steps:
Step 1 Enable/disable mirroring state;
Step 2 If mirroring state is enabled, choose a port as the monitoring port;
Caution:
⚫ Monitoring port cannot be link-aggregration port;
⚫ Only one port can be selected as monitoring port;
⚫ Monitoring port cannot be mirroring port at the same time.
Step 3 Select the mirroring ports and whether the packets to be mirrored are Rx, Tx or both
Rx /Tx.
None: Means to mirror none packets on the port;
Rx Port: Means only to mirror the packets received by the port;
