reset Ethernet bonding without rebooting

Question

I have the following Ethernet bonding configuration:

old configuration:

bond0
  eth0
  eth1
bond1
  eth2
  eth3

new configuration :

bond0
  eth0
  eth2
bond1
  eth1
  eth3

I have made the change and restart service network restart but cat /proc/net/bonding/bond0 and cat /proc/net/bonding/bond1 still shows the old configuration. I had to reboot the system to be able to see the new configuration. Is there a way to do this without reboot?

I am using RHEL6.5

Solution

Don't make any changes to the config files which do not reflect the current state of the system, otherwise the network scripts get confused when they read the config to stop networking, but the config files don't match what's actually configured.

The correct way to change network config files is first stop networking (service network stop), then make your config file changes, then start networking again (service network start).

Stopping the network service will remove network access, so make sure you're using out-of-band access (ILO, DRAC, etc) and not SSH or other network-based access.

You haven't mentioned what distribution are you running.

I have the same question for Ubuntu 18.04. There is no service named network there and it uses Netplan. I tried netplan apply and restarting systemd-networkd but those are not enough to change parameters like mii-monitor-interval or mode.
