dustpuppy passes unexpected LAN failover test

A few days ago, I did the smart thing and bonded the two Ethernet interfaces in dustpuppy:

green [imbrius@dustpuppy ~]$ /sbin/ifconfig bond0
bond0     Link encap:Ethernet  HWaddr 00:26:54:0B:3E:65
 inet addr:  Bcast:  Mask:
 RX packets:3370594 errors:0 dropped:0 overruns:1 frame:0
 TX packets:3215598 errors:0 dropped:0 overruns:0 carrier:0
 collisions:0 txqueuelen:0
 RX bytes:1820836866 (1.6 GiB)  TX bytes:2214959827 (2.0 GiB)

It’s in bonding mode 2 which does both RX and TX in a round-robin style and allows for increased bandwidth (~1.5x) and full 1x redundancy.  The redundancy is made more valid by the fact that the 3Com NIC is wired directly into vertical cabling (bad form, I know) to the backbone switch, while the nVidia NIC is connected to the local switch.

Today, I kicked the local switch under the desk and knocked the power cable out of it.  I didn’t realize it until I saw no green blinkenlights under the desk.  The bonding driver is working quite well, apparently.
