High inblock packet count on passive LAN interfaces

[vpx]

Hello everyone,

I just noticed high inblock packet counts on LAN interfaces which just act as parent interfaces for VLAN interfaces.

How can these high packet numbers be explained, are they originating from the attached switch?

130-200m seem to be a lot of packets per second.

I know the underlying real physical interface of a VLAN does not have to be enabled for a VLAN to be working but I had problems with a WiFi controller and enabling the interface solved it.

The LAN interfaces have the configuration type "none". What would fix these high packet counts without disabling the underlying LAN interfaces?

For comparison I'll show the packet counts of a normal active "Static IPv4" LAN interface vs. a passive LAN interface.

Thats 200 millipackets per second or a fifth of a packet or one packet every five seconds.

That's just some multicast, neighbour discovery, keepalive, whatever ... stuff from the switch or any other device on that untagged network.

Ah, thank you, that makes sense, maybe I should RTFM, I thought 'm' was for mega, i.e. millions. 

That would have been in the realm of a 100 GBit/s NIC.

Mega is M, milli is m.

To be honest, that has also confused me for a while.

Since the unit is packets/second, wouldn't it be nicer to see for example "0.2" instead of "200m" and just add k or M for the bigger values (>1/s)?
