Configuring the monitor port for the local mirroring group
To configure the monitor port for a mirroring group, use one of the following methods:
•
Configure the monitor port for the mirroring group in system view.
•
Assign a port to the mirroring group as the monitor port in interface view.
Configuration restrictions and guidelines
When you configure the monitor port for a local mirroring group, follow these restrictions and
guidelines:
•
Do not enable the spanning tree feature on the monitor port.
•
For a Layer 2 aggregate interface configured as the monitor port, do not configure its member
ports as source ports.
•
A mirroring group contains only one monitor port.
•
Use a monitor port only for port mirroring, so the data monitoring device receives only the
mirrored traffic.

Configure local port mirroring with multiple monitor ports
Typically, you can configure only one monitor port in a local mirroring group. To configure local port
mirroring to support multiple monitor ports, use the remote probe VLAN.
In Layer 2 remote port mirroring, mirrored packets are broadcast within the remote probe VLAN.
To broadcast mirrored packets to multiple local monitor ports through the remote probe VLAN,
perform the following tasks:
1.
Create a remote source group on the local device.
2.
Specify the reflector port for this mirroring group.
3.
Configure the remote probe VLAN for this mirroring group.
4.
Assign the local monitor ports to the remote probe VLAN.
