If you need a 2gbps NIC, you need to bond dual 1gbps NICs. It is done using the following way.
1. For your eth0 and eth1 (or whatever your 2 nics are named), you will put the following:
Code:
DEVICE=eth#
HWADDR=NIC HW address goes here
BOOTPROTO=none
ONBOOT=yes
USERCTL=no
MASTER=bond0
SLAVE=yes
Obviously change the eth# to eth0, eth1, or whatever the nic name is and change the HWADDR line to the correct hw addr of the NIC.
2. Now we need to create the ifcfg-bond0 file using the following command:
Code:
touch /etc/sysconfig/network-scripts/ifcfg-bond0
3. Open up the newly created bond0 file and put the following into it:
Code:
DEVICE=bond0
IPADDR="1.1.1.1"
NETMASK="255.255.255.0"
GATEWAY="1.1.1.1"
ONBOOT=yes
BOOTPROTO=none
USERCTL=no
BONDING_OPTS="miimon=80 mode=4 xmit_hash_policy=layer3+4"
Replace the IP, netmask and gateway with your respective values. Save and restart network:
Code:
/etc/init.d/network reload
You should now be running on a bonded nic. You can check using the ifconfig command and will see bond0 with the primary IP.
Note: If you are running intel nics, it is a smart idea to add the following to the /etc/grub.conf kernel line, at the end:
Code:
pcie_aspm=off
Then save and reboot the server. This will ensure that the NICs won't fall asleep.
