Hello everyone,
Now I’d like to share with you how to configure port mirroring.
Description:
Port Mirroring means dupplicated the Inbound or Outbound Traffic of one or some ports to other or others ports.
Use:
Port Mirroring can be used to capture of packet for analyst of Traffic as Monitoring or Troubleshooting purposes.
Example:
The traffic from port G0/0/2 will be Mirrooring (Observed, Copy) to the port G0/0/1
Port G0/0/1 is a observed
Port G0/0/2 is a mirror
<HUAWEI> system-view
[HUAWEI] observe-port1 interface gigabitethernet 0/0/1 //In this port is connected a Monitoring Device or some device with a Sniffer like WireShark to capture the packet for futher analyst
[HUAWEI] interface gigabitethernet 0/0/2 //The Inbound traffic will be copy to the Observer 1 in this case G0/0/1
[HUAWEI-GigabitEthernet0/0/2] port-mirroring to observe-port 1 inbound
Conclusion:
In some cases it is critical to have the capture of packet do speed up the troubleshooting since in this way we can determinate what it is wrong in the communication between peers. The request is send it correctly? The replay is arriving? In this way we can see it.
This is what I want to share with you today, thank you!
