Debian network bonding
Install the "ifenslave" package:
apt-get install ifenslave
Bond all of the available network interfaces by editing the file:
nano /etc/network/interfaces
And adding in place of the eth0 block:
auto bond0 iface bond0 inet static address 192.168.0.8 netmask 255.255.255.0 network 192.168.0.0 gateway 192.168.0.1 slaves eth0 eth1 eth2 eth3 bond_mode balance-tlb bond_miimon 100 bond_downdelay 200 bond_updelay 200
The, if you're at the DC you can unplug each network cable in-turn to test connectivity still.
