TitleC5210 - reboot the controller and lose http GUI access, even to the out-of-band management port
Symptoms
  • ExtremeWireless appliances lose Web GUI access after a reboot or upgrade.
  • Cannot restart the httpd or apachectl process due to a missing file in the certificate file directory.
Environment
  • ExtremeWireless appliance C-5210
  • Firmware 9.15.06 and earlier
Cause
  • Previous third party certificate removal from a Topology via the GUI Topology section did not remove the certificate path in the controller database files.
  • Changing the Topology IP address without updating the certificate files.
Resolution
  • In the CLI, enter the following commands:
  • EWC1.EXTR.com: topology
  • EWC1.EXTR.com: <Topology name>
  • EWC1.EXTR.com: l3
  • EWC1.EXTR.com: show
  • Verify the certificate/key is set to the correct value.
    • If using a third party certificate, the configuration line should read 'Custom certificate/key'.
    • If using the default certificates, the configuration line should read 'factory default certificate/key'.
  • Reboot the appliance if necessary.

If the GUI is still not attainable, please call the GTAC Support Group for additional guidance.
