Hello:
Velocloud devices interface use RX and TX is not implemented, the data is faulty on the NPM.
The correct OIDS (object no interface) are:
1.3.6.1.4.1.45346.1.1.2.3.2.2.1.38
1.3.6.1.4.1.45346.1.1.2.3.2.2.1.39
I think this is mandatory since velocloud is a bug player in SD-WAN.
Also NTA does not work as expected because the device keeps changing the interface ID that sources the traffic.
