The tipc netid defaults to 4711, if you need to change this, it must be
done before you assign an address to the nodes.

But you probably dont want/need to change it unless you run multiple tipc
networks on the same medium.

What NetFlow Analyzer can do for you? Monitors network bandwidth and traffic
patterns at an interface-level. Reveals which users, apps, and protocols are 
consuming the most bandwidth. Provides multi-vendor support for NetFlow, 
J-Flow, sFlow and other flows. Make informed decisions using capacity 
planning reports. https://ad.doubleclick.net/ddm/clk/305295220;132659582;e
