Hi!

On a SL6.5 machine we now have two connections to the same switch/vlan. One is 1GbE (eth0) and the other is 10GbE (eth5).
Could I just do a "brctl addif br0 eth5" and then "brctl delif br0 eth0" and it switch to use the 10GbE link?
After this we could change the network-scripts to make it work after reboot.
Will this prevent existing connections from being cut?

# brctl show
bridge name     bridge id               STP enabled     interfaces
br0             8000.18a9054c4d34       no              eth0
                                                        vnet1
br4             8000.00265556f190       no              eth4
                                                        vnet0
