What is netflow_vlan####?

I'm starting to see more and more of this type of interfaces, presumably because the routers have netflow export configured. A topologically equivalent router with only netflow enabled, but not exporting, does not have this interface.

interfaces.ifTable.ifEntry.ifDescr.130 : DISPLAY STRING- (ascii): netflow_vlan1014

Another variant is netflow_vlan1018.

A quick search shows a couple of edu sites have netflow_vlan1014 available for graphing on their cricket/mrtg sites.

Re: What is netflow_vlan####?

NetFlow collects traffic statistics by monitoring packets that flow through the switch and storing the statistics in the NetFlow table. SoNetflow VLAN it means collecting traffic for particular vlan through the switch
