Configuration Switch M8024-K, Server M710HD and Red Hat 5.6

Hello

I have to configure a Red Hat 5.6 and NPAR is enabled in the NIC Broadcom 57712, Red Hat recognizes the 4 interfaces from eth0 to eth1 and I configure the Switch M8024-K with 4 Vlan. In the Switch M8024-K the interfaces of the Blade is the TenGiga 1/0/1 and was assigned in mode general to the 4 Vlan. Now in Red Hat I need assign 1 Vlan each NIC. Example

eth0 ---> Vlan 10
eth1 ---> Vlan 20
eth2 ---> Vlan 30
eth3 ----> Vlan 40

Also I configured the Switch M8024-K with Bind MAC to Vlan

vlan association mac 0010.1897.DD30 10
vlan association mac 0010.1897.DD32 20
vlan association mac 0010.1897.DD34 30
vlan association mac 0010.1897.DD36 40

In the Operating System I configure the NIC. Example

ifcfg-eth0

DEVICE=eth0
IPADDR=172.10.10.10
NETMASK=255.255.255.0
GATEWAY=172.10.10.1
HWADDR=00:10:18:97:DD:30

ifcfg-eth1

DEVICE=eth1
IPADDR=172.20.20.10
NETMASK=255.255.255.0
GATEWAY=172.20.20.1
HWADDR=00:10:18:97:DD:32

The problem is the following

When I run a ping to gateway 172.10.10.1 no exist problem, but when I run a ping to Gateway 172.20.20.1 I received the message

Reply from 172.20.20.1 Destination host unreachable

I need to know if is neccesary configure the tag of Vlan in the eth1 assign the Vlan

Example

DEVICE=eth1.20
IPADDR=172.20.20.10
NETMASK=255.255.255.0
GATEWAY=172.20.20.1
HWADDR=00:10:18:97:DD:32
VLAN=yes

I will appreciate your help since I need to configure eth1 to eth3 without Vlan tag.

Thanks for your help
