[Bro] Arista Traffic Shunting

Here is how I have stuff setup:

1) in your site.bro:

@load conn-bulk.bro
@load react

redef GridFTP::size_threshold = 1048576; # 2 MB 
redef Bulk::size_threshold = 134217728 ; # 128 MB 

2) make sure react/dumbno.cfg has right values 

3) then: 

	a) ./dumbno.py dumbno.cfg setup

	b) ./dumbno.py dumbno.cfg >& /var/log/dumbno.log & 
	c) ./dumbno.py dumbno.cfg stats >& /var/log/dumbno.stats & 

4) @load conn-bulk.bro and "@load react" should get bro to start
flagging and acting on fat flows. 

tail on /var/log/dumbno.log should give you reasonable visibility into
on-going operations 

Hope this helps,

Also, as long as api management is enabled on the Arista switch, is there anything else on the switch that needs to be configured?
