Lab Environments

Network Connectivity Issues

If you are running into network connectivity issues within the lab environment, there are two common causes:

1. Systems are still powering on

Cause: It can take up to 10 minutes for all lab systems to become active and accessible.

Action Please wait a little longer and try again.

2. Issue with the underlying networking

Cause: We have seen this issue happen where the underlying networking has not connected the VMs correctly.

Action: Power off the lab environment using the Stop/Shutdown button in the top right corner of the lab screen (the one with all the VM tiles). Once all the VMs are powered off then power the lab back on using the Play/Start button in the top right corner. Rebooting systems will not help. The lab needs to be completely shut down to reset the networking configuration.

How do I Startup/Suspend/Shutdown my Lab Environment?

• When you are in the main lab environment screen, there are several lab controls in the top right corner.

• Click ️Play/Start to power on or resume all of the VMs.

• Click Pause/Suspend to suspend all powered-on VMs.

• Click Stop/Shutdown to power off all of the powered-on VMs gracefully.

  • Ensure you have saved any open files before initiating power-off; all unsaved work will be lost.

• Click Power to access advanced power options.
