Devices supporting Class-based QoS
NetProfiler can poll Cisco routers to retrieve statistics and configuration information for traffic classes and traffic policies defined in the router’s Quality of Service configuration. NetProfiler displays class-based QoS (CBQoS) traffic statistics in the Reports > All Reports > Interface Information report. more
NetProfiler stores the statistics for 30 days and can support up to 100 routers. The status of CBQoS polling is displayed on Administration > Devices/Interfaces page Synchronization tab when you select CBQoS Devices as the Device type.
To poll Cisco routers for CBQoS information, NetProfiler requires the following:
-
The router must support the CISCO-CLASS-BASED-QOS MIB.
-
QoS policies and traffic classes must be defined on the router.
-
The router must enforce persistence across all CBQoS MIB indexes, including cbQosConfigIndex, cbQosObjectsIndex, and cbQosPolicyIndex. Refer to the Cisco document titled " QoS CBQoS MIB Index Enhancements" for details.
-
NetProfiler must be configured to use SNMP v2c or 3 to poll the Cisco router for CBQoS information. This is set in the SNMP Polling popup window. Open the window by choosing Edit in the list of devices on either the Administration > Devices/Interfaces page Devices & Interfaces (Tree) tab or the Administration > Devices/Interfaces page Devices (List) tab. The per-device SNMP version setting overrides the Global SNMP version setting.
SNMP polling of CBQoS information can be enabled or disabled for each device. Note that SNMP polling for CBQoS information is separate and independent from SNMP polling for other switch and router information. When the "Copy SNMP settings to Switch Port Discovery" option is selected on the SNMP Polling popup window, CBQoS polling information is not included in the settings that are copied.
CBQoS polling is disabled by default. You can enable it in the SNMP Polling popup window for a supported device and choose a polling interval of 5 or 15 minutes.
NetProfiler polls the CBQoS source device for traffic statistics every 5 or 15 minutes, as specified. It polls the CBQoS source device for configuration information once each 24 hours.
You can manually initiate polling on the Administration > Devices/Interfaces page Synchronization tab by selecting CBQoS Devices as the Device Type and choosing a Poll selection from the Selected Actions or Global Actions menu.
If you disable polling for a device, the polling configuration and statistics are discarded. If you change the polling interval, the CBQoS statistics are discarded, but the polling configuration is saved.
