I tried backing up APIC running configuration using SolarWinds NCM with the custom device template I found here.
However, I noticed that the configuration file was incomplete and seems NCM stopped downloading the configuration when it detected # " on the config line.
Has anyone resolved this issue or had a workaround?
Many thanks!
