Figure 48 Local port mirroring implementation
As shown in
, the source port GigabitEthernet 1/0/1 and monitor port GigabitEthernet 1/0/2
reside on the same device. Packets of GigabitEthernet 1/0/1 are copied to GigabitEthernet 1/0/2,
which then forwards the packets to the data monitoring device for analysis.
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.
