Question:
Why does the Spectrum Discovery console fail to discover a range of ip addresses but I can discover them by "Model by IP"?
Environment:
Spectrum 10.x
Spectrum 10.1.x
Spectrum 10.2.x
Answer:
The cause was determined to be with the "ICMP Payload Size" being set to the default of 8 which is located under Advanced Options.
When the ICMP Payload Size was changed to 32 (Windows default), the devices were able to be discovered correctly from the Discovery Console.
