	In the following example, I use ports 13 and 15 on our Dell PowerConnect 6248 switch to form an LACP trunk to my machine, futuregadget, which will have a bonded network connection. The trunk name on my switch is called port-channel 7/channel-group 7. Ports 13 & 15 are assigned to port-channel 7 along with several other small config changes.
