Without going into the details of why (lets just say years of poor documentation, change control, management, etc) I have a need to be able to fully scan /16 networks as we have ended up with a lot of devices just plugged in and thrown an IP address without any care. As NPM is already populated with devices from valid subnets I'd like to be able to run a full scan of for example 10.123.0.0/16 in order to pick up any incorrectly configured devices or devices that have been put on that network without informing us. Which sadly happens quite a lot.
As we have 110 networks all assigned a /16 I would prefer to have a smaller number of longer running discoveries with multiple networks assigned (as these scans would only be ran monthly) rather than manually having to create 110 discoveries and hoping they manage to complete within the time frame.
Is there any way to tweak the timeout outside of the web console? Would be great if there was a check box saying "Run until Completed" but alas there is not...
