When troubleshooting network issues on Ray devices, it's important to follow a systematic approach to identify and resolve the problem. Here are some steps you can follow to troubleshoot network issues:
RAY.Life allows you to do initial troubleshooting of the network on the RAY Controller.
1. Goto your cluster
2. Then go to Dashboard
3. Click on the three dots below the action button
4. Then go to Debugging Utilities
In the Debugging utilities, we see multiple options here which can be used for troubleshooting.
1. Ping
The "ping" command is a useful tool for testing reachability and latency between devices.
Ping the IP address or hostname of the destination device you want to ping, you also select the exit interface for the ping packet and number of ping packets to be sent can be also selected.
2. Trace Route
A trace route (traceroute) is a diagnostic tool used to trace the path that data packets take from one networked device to another. It provides information about the route that packets follow, including the number of hops (intermediate devices), the IP addresses of each hop, and the round-trip time (RTT) for each hop.
3. Interface list
An "interface list" refers to a list of network interfaces or network adapters that are present on a device. A network interface is a connection point that enables a device to connect to a network. Each interface is associated with a physical port or a virtual network interface and has its own unique identifier, such as an IP address and a Media Access Control (MAC) address.
4. Showing Routing table
The routing table is used by the device to determine the best path for forwarding network traffic. When a packet arrives at the device, it consults the routing table to determine where to send the packet next based on the destination IP address of the packet.
For SD-WAN troubleshooting, In the routing table source address should be present, if not present it would be a kernel issue or else. You can raise a case regarding this on the Support.ray.life.
To better understand see the below image, here you can see under the red line the source address is not available.
5. Force ACS
When multiple APs operate on the same channel within proximity, they can cause interference with each other's signals. This interference can result in decreased network throughput, increased latency, and reduced overall network performance.
Check Audit logs
You can check the logs on the RAY controller. see the reference images.
Sometimes, the WAN port is flapping, in Audit logs we can investigate the port status and identify the issue.
Check Jobs
What is the 'Jobs' option in the RAY Cloud?
The "jobs" option provides you with Backend activity logs on the RAY cloud. For reference see the below image.
>>Go to cluster/Child cluster > Jobs
After Clicking on the Jobs, you will see multiple options there. For time-saving, you can customize the search.
Use the details you have, for example, Addresses, Serial no., Dates, and select types of jobs to fetch the pieces of information.
To learn more about Jobs follow the KB article provided below in the link.
Thank you,
