Rhel5.9 bond Configuration

1. Configure bond

1. ifcfg-bond0

# Advanced Micro Devices [amd] 79c970 [pcnet32 Lance]

Device = bond0

Bootproto = static

Onboot = Yes

Ipaddr = 10.0.26.27

Netmask = 255.255.255.0

Gateway = 10.0.26.1

2. ifcfg-eth1

# Advanced Micro Devices [amd] 79c970 [pcnet32 Lance]

Device = eth1

Bootproto = none

Onboot = Yes

Master = bond0

Slave = Yes

3. ifcfg-eth2

# Advanced Micro Devices [amd] 79c970 [pcnet32 Lance]

Device = eth2

Bootproto = none

Onboot = Yes

Master = bond0

Slave = Yes

4./etc/modprobe. conf configuration

Alias eth0 pcnet32

Alias scsi_hostadapter mptbase

Alias scsi_hostadapter1 mptspi

Alias scsi_hostadapter2 ata_piix

Alias net-pf-10 off

Alias IPv6 off

Options IPv6 disable = 1

Alias eth1 pcnet32

Alias eth2 pcnet32

Alias bond0 Bonding

Options bonding millmon = 100 mode = 1

Ii. view the status

1. Restart the network

/Etc/init. d/network restart

2. View bond running status

MII status: Up

MII polling interval (MS): 1

Up delay (MS): 0

Down delay (MS): 0

Slave interface: eth1

MII status: Up

Speed: 100 Mbps

Duplex: full

Link failure count: 0

Permanent hw addr: 00: 50: 56: A2: 4d: 00

Slave interface: eth2

MII status: Up

Speed: 100 Mbps

Duplex: full

Link failure count: 0

Permanent hw addr: 00: 50: 56: A2: 4d: 01

Iii. test bond

1. Disconnect eth1 network port

[[Email protected] network-Scripts] # ifdown eth1

2. Check the bond status. eth1 is offline and now eth2 takes over

[[Email protected] network-Scripts] # Cat/proc/NET/Bonding/bond0

Ethernet channel bonding DRIVER: v3.4.0-1 (October 7, 2008)

Bonding mode: Load Balancing (round-robin)

MII status: Up

MII polling interval (MS): 1

Up delay (MS): 0

Down delay (MS): 0

Slave interface: eth2

MII status: Up

Speed: 100 Mbps

Duplex: full

Link failure count: 0

Permanent hw addr: 00: 50: 56: A2: 4d: 01

3. Activate eth1

[[Email protected] network-Scripts] # IFUP eth1

4. Check the bond status. eth1 is online, but the network traffic is still running on eth2, and eth1 is used as a backup. (Previously, eth1 was used to carry traffic)
