Configuration restrictions and guidelines

When you configure port mirroring, follow these restrictions and guidelines:
•
A local mirroring group can contain multiple source ports, but only one monitor port.
•
Do not enable the spanning tree feature on the monitor port.
•
Use a monitor port only for port mirroring to make sure the data monitoring device receives and
analyzes only the mirrored traffic rather than a mix of mirrored traffic and other forwarded traffic.
