Hi, this has been raised before by myself and others. Personally my last post got zero response.
All it needs is a script which executes the command
show config status
and builds a table of the results (changed/not changed). The switch tells you whether the config has changed or not.
NET-HP2510g-16-MOCO417g(config)# sho config status
Running configuration has been changed and needs to be saved.
NET-HP2510g-16-MOCO417g(config)# sho config status
Running configuration is same as the startup configuration.
