I'm a newbie in network, so please understand me.
I have a bond network, but I added a bridge network to the bond as master using
nmcli con modify bond0 master br0
but after that, I lost IP address and other setting of the bond0 network, so I want to rollback to the previous status.
How to do it?
I tried
nmcli con modify bond0 connection.master none
nmcli connection up bond0
->Error: Connection activation failed: Can not find a master for bond0: Master connection not fo und or invalid
nmcli con modify bond0 master none
-> Warning: master='none' doesn't refer to any existing profile.
nmcli con modify bond0 connection.slave-type none
-> Error: failed to modify connection.slave-type: 'none' not among [bond, bridge, ovs-bridge, ovs -port, team, vrf].
Here is my settings
