2. Configure source CPUs for the
specified local mirroring
group.
• In standalone mode:
mirroring-group group-id
mirroring-cpu slot
slot-number-list { both |
inbound | outbound }
• In IRF mode:
mirroring-group group-id
mirroring-cpu chassis
chassis-number slot
slot-number-list { both |

By default, no source CPU is
configured for a local mirroring
group.
Configuring the monitor port for the local mirroring group
You can configure the monitor port for a mirroring group in system view, or assign a port to a mirroring
group as the monitor port in interface view. The two modes lead to the same result.
Configuration restrictions and guidelines
When you configure the monitor port for a mirroring group, follow these restrictions and guidelines:
• For the mirroring function to operate correctly, do not enable STP on the monitor port.
• When a Layer 2 aggregate interface is configured as the monitor port, do not configure its member
interfaces as source ports.
• A mirroring group contains only one monitor port.
• Use a monitor port for port mirroring only to make sure that the data monitoring device receives and
analyzes only the mirrored traffic rather than a mix of mirrored traffic and correctly forwarded
traffic.
• Directly connect the monitor port for local port mirroring in source CPU mode to the data monitoring
device. Disable these functions on the monitor port:
{ 802.1X.
{ IGMP snooping.
{ MAC address learning.
{ Spanning tree feature.
{ Static ARP.
