Exalogic VLAN bond issue

Question

Hi,
vlan module: 8021q used
For example
ref link; http://docs.oracle.com/cd/E18476_01/doc.220/e18478/commproc.htm#BEIHAIDA --- here they used multiple physical hosts not single ethernet port
Here 
in bracket oracle details and other is my details
1)  eth0 (1A-ETH-3) - ethernet port
2)  vlan121 (eth4, vlan 10 ) -     vlan 121
3)  vlan122 (eth5, vlan 11 ) -      vlan 122
I have a exalogic machine which has Oracle Linux 5.6- x64 bit
Created 2 VLANs with IP and bond interface if i start network service [service network restart], I
get hardware address conflicts error message on vlan 121, 122
i have 1 physical lan cord, creating eth0, multiple vlans, bond1, bond0 interfaces
i could see eth0 192.168.1.12, bond1 192.168.48.128 but vlan121, vlan122 no static ips displayed
Question : How can i build vlan121, vlan122 ip address should set as static ips (or) based on hardware address
when i run #ifconfig -a ==> default HwAddr displays common for all the vlans, bond1, eth0
# vim /etc/sysconfig/network-scripts/ifcfg-vlan121
DEVICE=vlan121
BOOTPROTO=none
ONBOOT=yes
IPADDR=192.168.48.129
#HWADDR=a2:c0:a0:a8:01:01
VLAN=yes
PHYSDEV=eth0

# vim /etc/sysconfig/network-scripts/ifcfg-vlan122

I'm not really sure I understand your question. If you want any or all network interface cards in a computer to be used for communication, then any or all need to be connected to a switch or network router using a cable. Every real and virtual NIC has a physical address (MAC), which the device broadcasts when initialized to tell other devices that it's there. The MAC address is a unique number. The mapping of an IP address to a MAC address is maintained by an ARP table.
Network redundancy typically shifts an IP address among available devices. If a devices fails, a standby is activated, which updates the ARP table to inform other devices of the change and IP communiation can continue. I have also seen non Linux systems, which actually modify the phsycial MAC address of a device. If you want to use mutliple NIC's to work in a team for performance, the system network stack needs to support inverse multiplexing and you need to connect each device to a managed network switch that supports Link Aggregation Ccontrol Protocol (802.3ad).
Your ping issue might be due to TCP/IP routing. Devices by default see each other only if they are phycially connected through a switch and share the same network or subnet. If you have devices with different subnets you need to configure a TCP/IP gateway or bridge. This is basic TCP/IP routing and knowledge, which is explained by many free sources available on the Internet. Just search Google for TCP/IP routing basics.
Update:
Looking at your TCP/IP configuration from the information you provided, your VLAN interface is not within the network (netmask) of your gateway, hence the VLAN interface has no knowledge of your other networks. So perhaps if you change your VLAN to 255.255.0.0 it will work.
