Example for Configuring Local 1:1 Port Mirroring

Networking Requirements

In Figure 8-12, the administrative department of a company communicates with the Internet through the switch, and the server (monitoring device) is directly connected to the switch.

The server is required to monitor Internet-bound traffic from the administrative department.

Configuration Roadmap

The configuration roadmap is as follows:
  1. Configure GE0/0/2 as the local observing port to forward mirrored packets to the server.
  2. Configure GE0/0/1 as the mirrored port to copy Internet-bound traffic from the administrative department and send the traffic to the local observing port.

Procedure

  1. Configure an observing port.

    # Configure GE0/0/2 of the switch as a local observing port.

    <HUAWEI> system-view
    [HUAWEI] sysname Switch
    [Switch] observe-port 1 interface gigabitethernet 0/0/2

  2. Configure a mirrored port.

    # Configure GE0/0/1 on the switch as the mirrored port and configure GE0/0/1 to copy received packets to the local observing port.

    [Switch] interface gigabitethernet 0/0/1
    [Switch-GigabitEthernet0/0/1] port-mirroring to observe-port 1 inbound
    [Switch-GigabitEthernet0/0/1] return

  3. Verify the configuration.

    # Verify the configuration of the observing port.

    <Switch> display observe-port
      ----------------------------------------------------------------------
      Index          : 1
      Untag-packet   : No
      Interface      : GigabitEthernet0/0/2
      ----------------------------------------------------------------------

    # Verify the configuration of the mirrored port.

    <Switch> display port-mirroring
      ----------------------------------------------------------------------
      Observe-port 1 : GigabitEthernet0/0/2
      ----------------------------------------------------------------------
      Port-mirror:
      ----------------------------------------------------------------------
           Mirror-port               Direction  Observe-port
      ----------------------------------------------------------------------
      1    GigabitEthernet0/0/1      Inbound    Observe-port 1
      ----------------------------------------------------------------------
