Re: NetworkManager behavior answers not found in docs

[Thomas HUMMEL <thomas hummel pasteur fr>]

Hello,

I was playing with the externally managed concept and I experienced the 
following :

modifying an autocreated/autoconnected profile corresponding to an 
externally managed device seems to be (silently) auto-reapplied.
Afterward, once NetworkManager takes over (and really manages the 
device), everything is back to normal. Is this a legit/normal situation ?

Ex :

# ip address add 192.168.10.200/24 dev eth1
# nmcli connexion modify eth1 802-3-ethernet.mtu 9000
# ip addr shows eth1 has changed its mtu for 9000, no device reapplied 
or connexion up has been needed and no message (as in nmcli device 
modify) telling anything has been reapplied.

My guess is that's normal since telling a profile has been reapplied 
would imply that de device is (normally) managed...Since behavior 
surprised me.

Thanks
