In old NCM (without web UI) there was setup that helped filtering for example this kind of infomation from REAL config changes: "! Last configuration change at 12:04:29 EETDST Wed Sep 17 2014". I don't find it from new version. Would be nice if switch reboot, or changing setup - writing to mem - and then changing it back as it was, wouldn't appear as "config change" to system. I'm getting useless config change report emails this way.
For some reason I'm getting those notifications even if there is no difference between startup and running config (in other words, config is saved to flash). That sounds as bug... So I may have two different problems.
