Diagnosing a CPE device
You can request diagnostic information and statistics, such as BGP, OSPF, and PIM protocol usage, from a CPE device. The diagnostic information returned in response to the request is displayed in the web interface of the orchestrator and, if necessary, can be downloaded as a TXT file.
Kaspersky SD-WAN also supports the following utilities for CPE device diagnostics:
- Ping is a utility for testing the connection between a CPE device and a specified IPv4 address. A report with the output of the utility is displayed in the orchestrator web interface.
- Traceroute is a utility for determining the route between a CPE device and a specified IPv4 address. A report with the output of the utility is displayed in the orchestrator web interface.
- Tcpdump is a utility for capturing traffic on a CPE device and writing this traffic to a report file. Capturing means a copy is made of the traffic, and the original traffic is relayed to its destination. The file with the captured traffic can be downloaded or deleted.
- Iperf is a utility for diagnosing network performance and writing the results to a report file. You can use the CPE device as an iperf server or as an iperf client. You can download or delete the network performance diagnostics file.
- Sweep is a utility for performing the following actions on a CPE device:
- Clearing the ARP cache
- Restarting the FRR (Free Range Routing) process
- Clearing the NAT session table
Running an utility is a task that the CPE device receives from the orchestrator; the task obeys the time period configured for the CPE device for sending REST API requests to the orchestrator. If you want the utilities to run sooner, you can enable interactive mode on the CPE device.
In interactive mode, the CPE device uses a shorter interval for sending REST API requests to the orchestrator. Interactive mode ends automatically when the specified duration has passed. You can specify the following interactive mode settings when configuring the connection of a CPE device to the orchestrator and controller:
- The period to wait until the CPE device sends another REST API request to the orchestrator in interactive mode
- The time after which the interactive mode is automatically disabled
