Using the remote probe VLAN to enable local port 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, 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 remote probe VLAN's member ports, you can monitor the local device's traffic on multiple data monitoring devices. Configure this feature by following these 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 are sent out of the ports connecting the data monitoring devices, and all data monitoring devices can thus receive these mirrored packets. 108

Using the remote probe VLAN to enable local port 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, 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 remote
probe VLAN's member ports, you can monitor the local device's traffic on multiple data monitoring
devices.
Configure this feature by following these 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
are sent out of the ports connecting the data monitoring devices, and all data monitoring devices can
thus receive these mirrored packets.
