Using the remote probe VLAN to enable local mirroring to
support multiple monitor ports
In typical local port mirroring configuration, you can configure only one monitor port in a local mirroring
group. As a result, you cannot monitor traffic of a local device on multiple data monitoring devices. To
do that, you can take advantage of the remote probe VLAN used in Layer 2 remote mirroring.
In Layer 2 remote port mirroring, a remote probe VLAN is configured, and the mirrored packets are
broadcast within the remote probe VLAN. By connecting multiple data monitoring devices to the member
ports of the remote probe VLAN, you can monitor the traffic of the local device on multiple data
monitoring devices.
Configure this feature in the following steps:
1. Configure a remote source mirroring group on the local device
2. Configure the monitored ports on the device as source ports of this mirroring group
3. Configure a remote probe VLAN for this mirroring group
4. Assign the ports connecting the data monitoring devices to the remote probe VLAN
In this way, when packets mirrored on the monitored ports are broadcast in the remote probe VLAN, they
will be sent out of the ports connecting the data monitoring devices, and all the data monitoring devices
can thus receive these mirrored packets.
Configuration restrictions and guidelines
The reflector port of a remote source mirroring group must be an access port and belong to the
•
default VLAN, VLAN 1.
• HP recommends that you configure an unused port as the reflector port of a remote source mirroring
group and disable STP on it.
Do not configure a combo interface as a reflector port.
•
• A mirroring group can contain multiple source ports.
To make sure that the port mirroring function works properly, do not assign a source port to the
•
remote probe VLAN.
• If you have already configured a reflector port for a remote source mirroring group, you can no
longer configure an egress port for it.
