PRTG Manual: SNMP Cisco CBQoS Sensor
The SNMP Cisco CBQoS sensor monitors network parameters using Cisco's Class Based Quality of Service (CBQoS) via the Simple Network Management Protocol (SNMP).
The sensor supports the classes Class Map, Match Statement, and Queueing.

The sensor has the following default tags that are automatically predefined in the sensor's settings when you add the sensor:
- cbqossensor
For more information about basic sensor settings, see section Sensor Settings.
Class Based QoS Specific
Setting |
Description |
|---|---|
Object Type |
The object type of the parameter that this sensor monitors. |
Interface |
The interface of the parameter that this sensor monitors. |
Description |
The description of the parameter that this sensor monitors. |
BitMask |
The number of available channels for the parameter that this sensor monitors. |

Sensor Display
Setting |
Description |
|---|---|
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.
|
Graph Type |
Define how this sensor shows different channels:
|
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. |
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 
under the corresponding setting name to disable the inheritance and to display its options.
For more information, see section Inheritance of Settings.
Which channels the sensor actually shows might depend on the target device, the available components, and the sensor setup.
