RHEL 5.5 NIC Bonding

I am new to linux. I have a falconstor CDP installation which runs on RHEL 5.5 (Tikanga). There is a vendor option to bond nics in either 802.3ad or round robin, I choose 802.3ad. The server is connected to a Cisco 3750 switch.

The problem is dropped packets and eth03 wont come up in the PO (suspended). I am getting reports of dropped packets. When I look at the network files, things dont look right. I am not posting this without doing homework, I have spent the last couple days looking into RHEL NIC Bonding. At this point, I need help, before I make the changes I think are necessary. I dont think Eth0 should have an IP and I am not entirely sure what kind of load-balancing RHEL supports.

This is what is on the server


Code:
DEVICE=bond0
IPADDR=192.168.0.27
NETMASK=255.255.255.0
USERCTL=no
BOOTPROTO=none
ONBOOT=yes
MTU=1500
BONDING_OPTS="mode=4 miimon=100 updelay=60000"
 
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=none
#IPADDR=192.168.0.27
#NETMASK=255.255.255.0

MTU=1500
MASTER=bond0
SLAVE=yes
 
DEVICE=eth1

BOOTPROTO=none
#IPADDR=10.0.0.3
#NETMASK=255.255.255.0

HWADDR=00:23:7d:e1:f8:68
