Information

 
TitleBlacklist MAC Import is creating a failed GUI page
Symptoms
  • Blacklist Import is creating a failed GUI page
  • Blacklist fails when adding a single manual entry via the GUI page
  • Import from a text file works, but the GUI is not accessible after the Import.
  • Issue is also seen when trying to add a Whitelist MAC address.
Environment
  • ExtremeWireless appliances
  • Firmware 9.21.14, 9.21.15, 9.21.16
Cause
OUI list has a special character for some vendors in the blacklist text file, causing a parsing failure.
The same parsing error can occur when adding a whitelist MAC address.

 
Resolution
Please upgrade to 9.21.17 to fix both issues. The 9.21.16 resolves just the importing issue but the manual single entry fix requires the 9.21.17.
