Layer 2 remote port mirroring configuration task list
CAUTION:
For a mirrored packet to successfully arrive at the remote destination device, make sure the VLAN ID of the
mirrored packet is not removed or changed.
To configure Layer 2 remote port mirroring, configure remote mirroring groups. When doing that,
configure the remote source group on the source device, and configure the cooperating remote
destination group on the destination device. If an intermediate device exists, configure the intermediate
devices to allow the remote probe VLAN to pass through.
H3C recommends that you not enable GARP VLAN Registration Protocol (GVRP). If GVRP is enabled,
GVRP may register the remote probe VLAN to unexpected ports, resulting in undesired duplicates. For
more information about GVRP, see Layer 2—LAN Switching Configuration Guide.
Do the following to configure Layer 2 remote port mirroring:
• On the source device, configure the source ports/CPUs, the remote probe VLAN, and the egress
port for the remote source group.
• On the destination device, configure the remote probe VLAN and the monitor port for the remote
destination group.
Complete these tasks to configure Layer 2 remote port mirroring:
