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 of a mirroring group, do not configure its member ports as source ports of the mirroring group.
A Layer 3 aggregate interface cannot be configured as the monitor port of a local mirroring group.
Use a monitor port only for port mirroring, so the data monitoring device receives only the mirrored traffic.
