Interface In/Out statistic explaination

[Frank17]

Imagine i have a cisco router where on Gi0/1 is the interface connected to the PPPoE , the Dialer 1 is the PPPoE connection itself and the G0/0 is the interface natting from all LAN devices to the outside.

With #show int stat i have these statistics :

My questions are :

If the Dialer is the responsable for the PPPoE tunnel, why the interface G0/1is having even more packet processed? Int G0/1 (physically connected to the PPPoE) is mirroring the same amount of traffic or are there some extra packets coming to this interface?

Hi there,

Gi0/1 will be sending and receiving Ethernet frames, the payload of which is a PPPoE packet generated by the dialer interface.  Therefore the outer Ethernet frame will always be larger and the Gi0/1 interface stats will report more data in/out.

cheers,

Seb.
