SG550 added a bunch of configuration changes to older SG500 switching in my network when plugged in.

one of our buildings has a handful of SG500 switches.  we're slowly replacing them with the SG550 series switches.  We plugged in the first SG550 today and it automatically added a bunch of configuration lines to the other switches in the network.  Everything seems to be working, but I'm trying to figure out why, if this is ok, or should I revert the changes back to the basic way it was before.   Nothing is really complicated with the network.   

basics = vlans 10-16, default / native 11, voice vlan14, ...

old configuration on the switch looks extremely simple:

interface gigabitethernet1/27
 switchport mode general 
 switchport general allowed vlan add 14 tagged 
!
interface gigabitethernet1/28
 switchport mode general 
 switchport general allowed vlan add 14 tagged 
!
interface gigabitethernet1/29
 description "Wireless AP"
 switchport trunk allowed vlan add 10,12-15 
!
interface gigabitethernet1/30
 switchport mode general 
 switchport general allowed vlan add 14 tagged 
!

after we plugged in the SG550 switch, it changed the configurations on the other network switches.  here's the same switch above, but after we plugged in the SG550

interface gigabitethernet1/27
 switchport mode general 
 switchport general allowed vlan add 14 tagged 
!
interface gigabitethernet1/28
 storm-control broadcast enable 
 storm-control broadcast level 10 
 storm-control include-multicast 
 port security max 10 
 port security mode max-addresses 
 port security discard trap 60 
 spanning-tree portfast 
 switchport mode general 
 switchport general allowed vlan add 14 tagged 
 macro description ip_phone_desktop
 !next command is internal.
 macro auto smartport dynamic_type unknown 
!
interface gigabitethernet1/29
 description "Wireless AP"
 spanning-tree link-type point-to-point 
 switchport trunk allowed vlan add 10,12-16 
 switchport trunk native vlan 1 
 macro description switch
 switchport default-vlan tagged 
 !next command is internal.
 macro auto smartport dynamic_type switch 
!
interface gigabitethernet1/30
 switchport mode general 
 switchport general allowed vlan add 14 tagged 

besides the wireless port complaining about the native vlan mismatch.  what else should I look for?  everything seems to be working ok, but it's only been 1 hour since this change too place.

the new firmware has a macro and smart port, if you have any issue please remove below lines works as expected.

 macro description switch
 macro auto smartport dynamic_type switch

it added those lines on the non-upgraded switches as well.  that's what threw me off.  it doesn't seem like it broke anything except changing the native vlan on my access point ports, but to change that config around isn't too bad as I have less than 20.  it's just odd for me when you plug in a new switch and the older gen switches change their config..

if you understand the macro it more useful, but sometimes we like the traditional way, some of the features hard to understand with macro, so people remove and start using a basic level to work - that is acceptable.
