When trying to edit the System Name or other information under Asset Information for a device and the user receives an error:
"Model write error [SPC-OCC-11736: An unknown failure occured]"
This error "Model write error [SPC-OCC-11736: An unknown failure occurred]" generally occurs if the user do not have write permissions to the device.
1. Verify that the device is using a R/W string or that the user has permissions to write to the device
2. Rediscovering the device using Read / Write community string may also fix the issue
