Common Mirroring Operations : Configuring Port Mirroring

Configuring 1:1 Port Mirroring

You can copy packets on a mirrored port to an observing port. For example, copy incoming packets (received packets) on mirrored port GE0/0/2 to observing port GE0/0/1. GE0/0/1 is directly connected to a monitoring device.

<HUAWEI> system-view
[HUAWEI] observe-port 1 interface gigabitethernet 0/0/1
[HUAWEI] interface gigabitethernet 0/0/2
[HUAWEI-GigabitEthernet0/0/2] port-mirroring to observe-port 1 inbound

Configuring 1:N Port Mirroring

You can copy packets on one mirrored port to N observing ports. For example, copy incoming packets (received packets) on mirrored port GE2/0/1 to observing ports GE1/0/1 through GE1/0/3. These observing ports are directly connected to monitoring devices.

• Configure observing ports one by one.

  <HUAWEI> system-view
  [HUAWEI] observe-port 1 interface gigabitethernet 1/0/1
  [HUAWEI] observe-port 2 interface gigabitethernet 1/0/2
  [HUAWEI] observe-port 3 interface gigabitethernet 1/0/3
  [HUAWEI] interface gigabitethernet 2/0/1
  [HUAWEI-GigabitEthernet2/0/1] port-mirroring to observe-port 1 inbound
  [HUAWEI-GigabitEthernet2/0/1] port-mirroring to observe-port 2 inbound
  [HUAWEI-GigabitEthernet2/0/1] port-mirroring to observe-port 3 inbound

• Configure observing ports in a batch (only in V200R005 and later versions).

  <HUAWEI> system-view
  [HUAWEI] observe-port 1 interface-range gigabitethernet 1/0/1 to gigabitEthernet 1/0/3
  [HUAWEI] interface gigabitethernet 2/0/1
  [HUAWEI-GigabitEthernet2/0/1] port-mirroring to observe-port 1 inbound

Configuring N:1 Port Mirroring

You can copy packets on N mirrored ports to one observing port. For example, copy incoming packets (received packets) on mirrored ports GE0/0/1 through GE0/0/3 to observing port GE0/0/10. GE0/0/10 is directly connected to a monitoring device.

<HUAWEI> system-view
[HUAWEI] observe-port 1 interface gigabitethernet 0/0/10
[HUAWEI] interface gigabitethernet 0/0/1
[HUAWEI-GigabitEthernet0/0/1] port-mirroring to observe-port 1 inbound
[HUAWEI-GigabitEthernet0/0/1] quit
[HUAWEI] interface gigabitethernet 0/0/2
[HUAWEI-GigabitEthernet0/0/2] port-mirroring to observe-port 1 inbound
[HUAWEI-GigabitEthernet0/0/2] quit
[HUAWEI] interface gigabitethernet 0/0/3
[HUAWEI-GigabitEthernet0/0/3] port-mirroring to observe-port 1 inbound
[HUAWEI-GigabitEthernet0/0/3] quit
