<%NUMBERING1%>.<%NUMBERING2%>.<%NUMBERING3%> PRTG Manual: SNMP Cisco ASA VPN Traffic 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.

IPv6

This sensor supports IPv6.

Performance impact

This sensor has a low performance impact.

Knowledge Base

Knowledge Base: I get the error PE123 when using the SNMP Cisco ASA VPN Traffic sensor. What can I do?

Remote IP Address

The IP address of the connection that this sensor monitors.

PRTG 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.

The 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.

You can set a different primary channel later by clicking 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.
  You 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.

Downtime

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.

Total

The total traffic

Traffic In

The incoming traffic

This channel is the primary channel by default.

Traffic Out

The outgoing traffic
