Hi,
We recently received a new switch/router and wanted to copy the current configuration from the old device onto the new one. After uploading the config file by using a tftp server and writing it to startup-config, I promptly reloaded the device, to get the new configuration running. Connectivity was OK and everything was/is working fine. I logged on and took a look at the configuration and I noticed a few different things :
1. The version/release of the IOS is different. It was 15.2, while now it is 16.3.
2. There are various statements in the configuration which aren't anywhere in the config file I uploaded. I see statements such as :
- vstack,
- class-map match-any system-cpp-police-topology-control (30 lines with descriptions)
- policy-map port_child_policy (25 lines)
- ip access-list extended AutoQos-4.0-wlan-Acl-Bulk-Data (nearly 50 lines)
- ap dot11 airtime-fairness policy-name Default 0
ap group default-group
ap hyperlocation ble-beacon 0 (5 lines)
From what I've read, most of them are used for wireless functionalities (access points, etc.) : stuff I don't need. Can I remove them without creating any problem ? Furthermore, I thought when I restarted the device, only what is in the startup-config gets loaded into memory : how can new commands get there? I copied my file onto the startup-config so I know what should be there....or I at least I thought I knew.
Thanks for any help you can give to this newbie!

There are certain commands that IOS (or IOSXE etc) self generates and inserts into the startup config. You have discovered some of them. Since they are self generated there is not really any way to remove them. There are some of them that you do not need or use. But they do no harm and you should not worry about them.
