I've just purchased a server board with two 1 gig lan ports. I would like to set one up for inbound traffic and the other for outbound traffic. Can this be done??
If this isn't possible is there another way to use these two ports to enhance network through-put??
Your switch must support trunking of some sort. Most Cisco, or SMC
Its not trunking support that you need. Trunking is used for the spanning of VLAN information. Natively cisco switches will support the setup as described below. I have various setups using the bonding module, albeit that most of them are setup with mode=1 in modprobe.conf, which is the configuration for fail over rather than increased bandwidth. I also use the 8021q module with bonding to join multiple vlans
With the cisco switches (IOS and CATOS) it works whether the switchports are in access or trunk mode
you want to bond the interfaces. The files you need to edit are /etc/sysconfig/network-scripts/ifcfg-bond0 /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/ifcfg-eth1 /etc/modprobe.conf
