The SNMP Cisco ASA VPN Traffic sensor monitors the traffic of an Internet Protocol Security (IPsec) VPN connection on a Cisco Adaptive Security Appliance via the Simple Network Management Protocol (SNMP).

Consider the following remarks and requirements for this sensor:



IPsec connections

  • This sensor can monitor IPsec connections only.

Permanent connections

  • This sensor is intended to monitor permanent connections. It shows an error if a connection is interrupted.


  • This sensor supports IPv6.

Performance impact

  • This sensor has a low performance impact.

Remote IP Address

The IP address of the connection that this sensor monitors.

i_round_redPRTG shows this value for reference purposes only. We strongly recommend that you only change it if the Paessler support team explicitly asks you to do so. Wrong usage can result in incorrect monitoring data.

Sensor Behavior

Define the sensor status if no active connection is available:

  • Show down status if no connection is active (default): Set the sensor to the Down status if no connection is active.
  • Show warning status if no connection is active: Set the sensor to the Warning status if no connection is active.
  • Stay in up status if no connection is active: Stay in the Up status if no connection is active.

IKE Version Handling

Select the engine for the Internet Key Exchange (IKE) version handling:

  • IKEv1 (default): Select this option if the tunnel on the device uses IKEv1.
  • IKEv1 and IKEv2: Select this option if the tunnel on the device uses IKEv1 or IKEv2.

i_round_blueThe IKEv1 and IKEv2 option is in beta status and might not work properly.

Primary Channel

Select a channel from the list to define it as the primary channel. In the device tree, PRTG displays the last value of the primary channel below the sensor's name. The available options depend on what channels are available for this sensor.

i_round_blueYou can set a different primary channel later by clicking b_channel_primary below a channel gauge on the sensor's Overview tab.

Graph Type

Define how this sensor shows different channels:

  • Show channels independently (default): Show a graph for each channel.
  • Stack channels on top of each other: Stack channels on top of each other to create a multi-channel graph. This generates a graph that visualizes the different components of your total traffic.
    i_round_redYou cannot use this option in combination with manual Vertical Axis Scaling (available in the channel settings).

Stack Unit

This setting is only visible if you select Stack channels on top of each other above.

Select a unit from the list. PRTG stacks all channels with this unit on top of each other. By default, you cannot exclude single channels from stacking if they use the selected unit. However, there is an advanced procedure to do so.

Inherited Settings

By default, all of these settings are inherited from objects that are higher in the hierarchy. We recommend that you change them centrally in the root group settings if necessary. To change a setting for this object only, click b_inherited_enabled under the corresponding setting name to disable the inheritance and to display its options.

i_square_cyanFor more information, see section Inheritance of Settings.

Channel List

i_round_blueWhich channels the sensor actually shows might depend on the target device, the available components, and the sensor setup.




In the channel table on the Overview tab, this channel never shows any values. PRTG uses this channel in graphs and reports to show the amount of time in which the sensor was in the Down status
