Slave interface of bond doesn't get automatically activated after `ifup` when NetworkManager is used in RHEL 7
Issue
After bond0 is deactivated on NIC managed by NetworkManager the slaves gets deactivated but after reactivating the bond0 the slaves have to be activated manually:
# nmcli con down/up bond0
or
# ifup bond0
It is still necessary to do
# nmcli dev con slave1/slave2
However when NetworkManager is not used the slaves are automatically enabled with bond0.
Environment
Red Hat Enterprise Linux 7
