Configuring the monitor port for the local mirroring group
CAUTION:
Do not enable the spanning tree feature on the monitor port.
Either you can configure the monitor port for a mirroring group in system view, or you can assign the
current port to a mirroring group as the monitor port in interface view. The two methods lead to the same
result.
Configuration restrictions and guidelines
When you configure the monitor port for a local mirroring group, follow these restrictions and guidelines:
•
A mirroring group contains only one monitor port.
•
H3C recommends that you use a monitor port for port mirroring only. This is to make sure that the
data monitoring device receives and analyzes only the mirrored traffic rather than a mix of mirrored
traffic and other traffic.
•
For Layer 3 port mirroring, the device can only mirror information about Layer 3 and upper layers
of packets but cannot mirror Layer 2 information, with the source MAC address as local device
MAC address, and the destination MAC address 00-0F-E2-41-5E-5B.
