How does the VCN3020 capture packets? What are the packet capturing method and procedure

Yes. Run the capture-packet command to configure the packet capturing function. The packets captured can be displayed directly on a terminal or be stored in the storage media of the device.

S series switches (except S1700 switches) support the packet capturing function. This function can be used if you need to capture packets for analysis. Packets that can be captured include service packets and packets sent to the CPU. Configuration example: 1. Capturing service packets [HUAWEI] capture-packet interface gigabitethernet 1/0/1 destination file capture.cap terminal //Information of captured packets is not provided here. 2. Capturing packets sent to the CPU [HUAWEI] capture-packet cpu destination file cfcard:/abc.cap //Information of captured packets is not provided here.

The method of capturing packets of TE30 is as follows: TE30 has only one network port. To capture packets, switch port mirroring must be performed first and then the Wirshark can be used for packet capture. The method of capturing packets of TE40, TE50, and TE60 is as follows: Log in to the endpoint web interface, choose System Settings > Network > IP > Common Settings and enable the hub network port mode. Then the PC can be connected to the LAN2 network port for packet capture using a tool such as Wirshark.

Packet capturing method for the TE30: The TE30 has only one network port. To capture packers for the TE30, first capture packets through the mirrored port on the switch and then use Wireshark to capture packets. On the web interface, choose System Settings > Network > IP > Common Settings and enable the Hub network port mode. Then connect the PC to the LAN2 port on the endpoint and use the packet capturing tool such as Wireshark to capture packets.

To capture packets on a new version of ViewPoint 8650C: Signaling packets: Log in to the MCU web interface to capture signaling packets. Media packets: Capture media packets through port mirroring on the switch that the MCU connects to.
