Barracuda CloudGen Firewall

CC SD-WAN Page

  • Last updated on

The Control Center SD-WAN page provides a geographic map interface for fast access to frequently needed CloudGen Firewalls with configured site-to-site VPN tunnels, showing real-time statistics of SD-WAN traffic. To display tunnel status information on the SD-WAN page, go to Global Settings > CC Parameters and enable Poll Box VPN Status. To access the SD-WAN page, click the CONTROL tab and select the SD-WAN icon.

The following elements provide information on the SD-WAN dashboard:

  • Topology
  • SD-WAN Status
  • SD-WAN Summary
  • State Over Time
  • Data Transfer

Topology

The Topology element provides a global overview of Control Center-managed Barracuda CloudGen Firewalls with configured VPN tunnels that have been added to the Status Map page. For more information, see CC Status Map Page. Locations with VPN tunnels are displayed as blue circles; firewalls that are deployed in a Cloud are displayed in violet. To view details such as firewall name and number and status of configured VPN tunnels, move the mouse over a point on the map. Use the mouse wheel to zoom the display in and out.

Right-clicking in the window directly on a location opens a dedicated context menu with the following entries:

  • Connect to Primary – Opens the VPN > Site-to-Site window, displaying the details of the primary VPN tunnel of the selected appliance as a new tab inside the current Barracuda Firewall Admin instance. For more information, see VPN Tab.
  • Connect to Secondary (if configured) – Opens the VPN > Site-to-Site window of the selected appliance as a new tab, displaying the details of the secondary VPN tunnel. For more information, see VPN Tab.

In case of HA, login is only possible for the active firewall.

SD-WAN Status

The SD-WAN Status element displays a graph showing the status of the configured VPN tunnels in numbers and percentage, indicated by different colors.

The chart provides the following details:

  • Ok – Shows the number of active healthy VPN connections.
  • Fail – Shows the number of VPN tunnels with status Fail.
  • Warning – Shows the number of VPN tunnels with status Warning.
  • Disabled – Shows the number of VPN tunnels with status Disabled.

For detailed information on the different VPN tunnel states, see the Status Section in VPN Tab.

State Over Time

The State Over Time element provides time-based information on the traffic that flows through VPN tunnels on which issues have been detected, according to the configured filter. Healthy tunnels are not listed here.

When expanded for a VPN tunnel, additional lines display the traffic details according to configured VPN transport classes. Click the arrow icon on the left of an entry to expand the SD-WAN traffic details:

  • Bulk – Shows the statistics for cheap and potentially unreliable connections classified as Bulk in the SD-WAN configuration.
  • Quality – Shows the statistics for more reliable connections, classified as Quality.
  • Fallback – Shows the statistics for the most expensive connections, classified as Fallback.

For more detailed information, see SD-WAN.

The colors of the lines indicate the connection status.

Possible State over Time colors for tunnels:

  • White – Unknown, no data from CC.
  • Grey – Tunnel status is Offline.
  • Green – Tunnel status is Healthy.
  • Orange – Tunnel status is Degraded.
  • Red – Tunnel status Down.

Possible state over Time colors for transports:

  • White – Unknown, no data from CC.
  • Green – All transports of the tunnel are up.
  • Grey – Transport is down (disabled/switched off).
  • Red – Transport status is Fail.
  • Blue – Transport status is Standby.

SD-WAN Summary

The SD-WAN Summary element displays the bandwidth consumed by your top-10 VPN tunnels according to the configured filter.
