Netgear R9000 - different interfaces meaning and explanation

[Arnout Verbeken]

Hello,

I have a R9000 router with Voxel's firmware. I want to monitor my router with snmp.
SNMP install went fine and I can do an snmpwalk.

Now I am wondering what all the interfaces are and which has use to monitor (I mostly want to see my total bandwidth utilisation on LAN/WAN/VPN)

I found the following interfaces:

lo
eth0
eth1
eth2
sit0
pas0
wlan0
ifb0
ifb1
bond0
br0
brwan
ethlan
ethwan
wifi0
wifi1
ath1
ath0
tun0

My main doubt is the difference between br0<>brwan, the different wifi's and the different ath's.
Also, is tun0 traffic also counted with brwan/br0 or is that a completely seperate interface to the outside.

If somebody would be able to give me some more information on this, I would really appreciate that.


Thanks
