Hi All,

Here is the problem.
Currently we have 4 NICs on my server:
eth0 eth1 bond to bond0
eth2 eth3 bond to bond1

First of all, I configured a 4 vlans vlan20-vlan23
like this: ifcfg-bond0.20
ifcfg-bond0.21
ifcfg-bond0.22
ifcfg-bond0.23

But, vlan22 and vlan 23 doesn't work after restarting network and I find the mistake is the vlan 22 and vlan 23 should under bond1. so I changed ifcfg-bond0.22 and ifcfg-bond0.23 to ifcfg-bond1.22 ifcfg-bond1.23, but this change doesn't take effect after network restarted. The interfaces are still under bond0.

Please help. Thanks in advance.

You shouldn't move ifcfg-bond0.22 to ifcfg-bond1.22 and should do like following.
1)Delete vlan22 and vlan23
2)Create them again under bond1.

Yes, This works Thanks.
