Troubleshooting scenarios and tips

The following ThinkAgile SXM Series network connectivity issues can often be identified and resolved quickly.

Network connectivity issues​

The following actions can help resolve network connection issues:

  • Ensure that the DNS settings are correct.

  • Ensure that the border switch settings are correct.

  • Check for any errors in the switch configuration file.

  • Check the data path. Ping between the next hop interfaces from the TOR and BMC switches.

  • Check the gateway. Each switch in the solution should be able to ping the point-to-point links and IP addresses of the other switches.

  • Test the connection between the server host nodes and the network devices. Ping from the server nodes to the network devices and towards the uplink to the external network.
