Why, oh why, would you, #Cisco, implement #QinQ so incorrectly?

> PPP over Q-in-Q encapsulation supports configurable outer tag Ethertype. The configurable Ethertype field values are 0x8100 (default), 0x9100, and 0x9200.

Why not use 0x88A8 like everybody else? Why would you not even consider this standard value as an acceptable config?

F*** U, Cisco.

Do you know if someone can have ON A SINGLE TRUNK, a native vlan, some 802.1q frames and some 802.1ad frames?

That's technically feasible, but it sounds crazy. Is it allowed by the specs?
