Some monitoring points have pairs of adjacent ports labeled ‘B/P’ or ‘bypass’. These are 2-port, bypass switches or bridges, and all they do is forward traffic from one port to the other, as if the network medium was uninterrupted.

The bypass continues to forward traffic even if the monitoring point loses power. This enables the monitoring point to be positioned inline, i.e., between two network devices, so that usage monitoring has access to the traffic you want to monitor/capture.

Bridges, although they have two ports, are configured as a single interface. One bridge, ‘bridge0’, is enabled by default and can’t be reconfigured. If you want to monitor multiple points in your network and the monitoring point is an r40 model or higher, a second bridge, ‘bridge1’, can be configured.

Web admin

Web admin

  1. Complete monitoring point setup.
  2. Log in to Web Admin.
  3. Click Flowview Settings.
  4. Click Capture Interfaces.

  6. Restart the monitoring point.

Admin API

  1. Discover your monitoring point hostname at > Manage Monitoring Points.
  2. Plug the monitoring point hostname into this url, under the Interface resource open POST /interface/.
  3. Paste the following JSON into the white box, and click Submit.

      "name": "bridge1"
  4. In the response, look for 'success': true, which lets you know that the interface was successfully created and configured.
  5. Next we’ll need to reboot the monitoring point in order to apply the changes. Under the Appliance resource open PUT /appliance/, set ‘action’ to ‘reboot’ and then click Submit. You will lose connectivity to the Admin API.
  6. To confirm that the new interface exists open GET /interface/ under the Interface resource and click Submit.
