Configuration prerequisites

z The MAC address to be matched is determined.

z The destination port is determined.

Configuration procedure

Follow these steps to configure MAC-based mirroring:

To do… Use the command… Remarks

Enter system view system-view —

Create a local or remote source

mirroring group mirroring-group group-id

{ local | remote-source } Required

Configuring MAC-Based

Mirroring

mirroring-group group-id

mirroring-mac mac vlan

vlan-id Required

Configure the destination port

for the mirroring group mirroring-group group-id

monitor-port monitor-port-id

Required

Note that you need not

configure the destination port

on the source switch when

configuring MAC-based remote

mirroring.

Configuration example

Configure MAC-based mirroring to mirror packets whose source/destination MAC addresses match

000f-e20f-0101 to port GigabitEthernet 1/0/2 on the local device.

Configuration procedure:

<device> system-view

[device] mac-address static 000f-e20f-0101 interface Gigabitethernet 1/0/1 vlan 2

[device] mirroring-group 1 local

[device] mirroring-group 1 mirroring-mac 000f-e20f-0101 vlan 2

[device] mirroring-group 1 monitor-port GigabitEthernet 1/0/2

Configuring VLAN-Based Mirroring

You can configure VLAN-based mirroring for a remote source mirroring group to implement the

VLAN-based remote mirroring function.

Configuration prerequisites

z The VLAN to be monitored is determined.

z The destination port is determined.
