RHEL Introduced Changes in How Network Bonding is Configured: RHEL5U1 Kernel 2.6.18-53.1.19

Example:
[root@lass1 ~]# cat /proc/net/bonding/bond0
Ethernet Channel Bonding Driver: v3.1.2 (January 20, 2007)
Bonding Mode: adaptive load balancing
Primary Slave: None
Currently Active Slave: eth1
MII Status: up
MII Polling Interval (ms): 100
Up Delay (ms): 0
Down Delay (ms): 0
Slave Interface: eth1
MII Status: up
Link Failure Count: 0
Permanent HW addr: 00:14:22:13:b7:e7
Slave Interface: eth2
MII Status: up
Link Failure Count: 0
Permanent HW addr: 00:14:22:13:b7:e8
Example of ifconfig:
[root@lass1 ~]# ifconfig
bond0 Link encap:Ethernet HWaddr 00:14:22:13:B7:E7
inet addr:192.168.116.211 Bcast:192.168.116.255
Mask:255.255.255.0
inet6 addr: fe80::214:22ff:fe13:b7e7/64 Scope:Link
UP BROADCAST RUNNING MASTER MULTICAST
MTU:1500 Metric:1
eth1 Link encap:Ethernet HWaddr 00:14:22:13:B7:E7
inet6 addr: fe80::214:22ff:fe13:b7e7/64 Scope:Link
UP BROADCAST RUNNING SLAVE MULTICAST
MTU:1500 Metric:1
eth2 Link encap:Ethernet HWaddr 00:14:22:13:B7:E8
inet6 addr: fe80::214:22ff:fe13:b7e8/64 Scope:Link
UP BROADCAST RUNNING SLAVE MULTICAST
MTU:1500 Metric:1
Note: Old way of configuring bonds in /etc/modprobe.conf will still be supported
for some time as long as options line is on a separate line from alias line.
Example:
[root@boss1 ~]# cat /etc/modprobe.conf
alias eth0 bnx2
alias eth1 bnx2
