    New script, analogous to Mike's node_traffic script. Basically, it · b885ce89

    was driving me nuts that we do not have an easy way to see what is
    going on *inside* the fabric.
    So this one reports on traffic across trunk links and interconnects
    out of the fabric.  Basic operation is pretty simple:
    	Usage: switch_traffic [-rs] [-i seconds] [switch[:switch] ...]
    	Reports traffic across trunk links and interconnects
    	-h          This message
    	-i seconds  Show stats over a <seconds>-period interval
    So with no arguments will give portstats style output of all trunk
    links and interconnects in the database. Trunk links are aggregate
    numbers of all of the trunk wires that connect two switches.
    The -i option gives traffic over an interval, which is much more
    useful than the raw packet numbers, since on most of our switches
    those numbers have probably rolled over a few times.
    You can optionally specify specific switches and interconnects on the
    command line. For example:
    boss> wap switch_traffic -i 10 cisco3 ion
    Trunk                    InOctets      InUpkts   InNUpkts   ...

    NOTE that the above output is abbreviated so it does not wrap in the
    git log, but you get the idea.
    Or you can specify a specific trunk link:
    	boss> wap switch_traffic -i 10 cisco3:cisco8
    Okay this is all pretty basic and eventually it would be nice to take
    these numbers and feed them into mrtg or rrdtool so we can view pretty
    graphs, but this as far as I can take it for now.
    Maybe in the short term it would be enough to record the numbers every
    5 minutes or so and put the results into a file.
