Troubleshooting and Monitoring Juniper BNG CUPS

Many of the existing mechanisms for troubleshooting an MX Series BNG are available for troubleshooting Juniper BNG CUPS. Most of the BNG functionality is on the BNG CUPS Controller; therefore, you perform the majority of the troubleshooting on the BNG CUPS Controller.

The following troubleshooting mechanisms are available on the BNG CUPS Controller:

  • Tracelogs

  • Shared memory logs

  • Operational and troubleshooting commands for the following components:

    • Node management

    • DHCP and DHCPv6

    • PPP

    • L2TP

    • DVLAN

    • AAA

    • Subscriber management

    • Subscriber groups

    • Load balancing groups

The following troubleshooting mechanisms are available on the BNG User Plane:

  • Tracelogs

  • Shared memory logs

  • Operational and troubleshooting commands for the following components:

    • Node management

    • Subscriber management

Centralized Logging Using Broadband Edge Event Collection and Visualization

Broadband Edge (BBE) Event Collection and Visualization is an event collection application that is meant to operate with Juniper's Broadband Edge cloud applications, such as Juniper BNG CUPS Controller and Address Pool Manager (APM).

BBE Event Collection and Visualization collects syslog events and records them in a time-series database. You can view the recorded events through the BBE Event Collection and Visualization Dashboard. The BBE Event Collection and Visualization Dashboard is a GUI-based visualization tool that enables you to view recorded events according to a defined filter, which can be within a specific time range. The Dashboard also provides powerful search and visualization tools through which you can correlate recoded events from multiple sources (for example, from APM or from the Kubernetes cluster).

Figure 1 shows an example of the BBE Event Collection and Visualization Dashboard.

BBE Event Collection and Visualization can be installed in the same Kubernetes cluster as the Juniper BBE applications (BNG CUPS Controller and APM). The installation follows the same model (installed from the jump host). For BBE Event Collection and Visualization installation instructions, see Broadband Edge Event Collection and Visualization Installation Guide.
