Centos 5 + vlan -> centos6 + vlan = what has changed?

Good afternoon,

I transfer the system to new hardware and at the same time the OS. There was Centos 5. x, one physical network + 2 vlans (eth1, vlan16, vlan31). Everything works like clockwork for many years.

Now CentOS 6.5, one physical network + 2 of the same vlans. Plugged into the same port on the switch (this means that all vlans are configured there). All the same, hostnames, ip - all..

Eth0

[root@pg ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0 | grep -vP '^#'DEVICE=eth0BOOTPROTO=noneONBOOT=yesHWADDR=08:60:6e:d6:9e:00

Eth0.16

[root@pg ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0.16 | grep -vP '^#'VLAN=yesDEVICE=eth0.16ONBOOT=yesBOOTPROTO=staticTYPE=EthernetIPADDR=192.168.16.33NETMASK=255.255.255.0BROADCAST=192.168.16.255GATEWAY=192.168.16.1

Eth0.31

The interfaces are raised, but only eth0. 31 works (it pings both inside and outside, eth0. 16 does not pass anything). What's wrong?

I've always done it only on CentOS 5, everything works there..

P. s. I created files for vlans in the form of ifcfg-ethX.id, and as ifcfg-vlanid
