QinQ ethertype?

[edit]

I was under the impression that Q in Q used the ethertype of 0x9100 in the outer tag and the ordinary Q type 8100 in the inner tag. The graphics states that both tags use 8100. Does anyone knows what is correct? —Preceding unsigned comment added by 212.73.30.50 (talk) 13:31, 7 December 2009 (UTC)[reply]

I agree too. The Q-in-Q should have an EtherType of 0x9100. If it had 0x8100, I guess there is no way to differentiate whether it is a 1Q tag or a Q-In-Q tag. —Preceding unsigned comment added by 192.5.246.142 (talk) 09:58, 14 December 2010 (UTC)[reply]

According to protocol, The outer EtherType is 88a8 and the inner EtherType is 8100.— Preceding unsigned comment added by Lay1421 (talkcontribs) 09:22, 17 June 2011 (UTC)[reply]

Yes only the linux networking devs think the types are the same. 2001:A60:1629:B201:7A24:AFFF:FE42:3EA5 (talk) 12:43, 30 January 2015 (UTC)[reply]

I'm fairly sure that the graphic should be updated to 0x88a8 ... According to http://standards.ieee.org/develop/regauth/ethertype/eth.txt there is no registration for 0x9100.

Frame size

[edit]

Ethernet frame indicates that maximum frame size was increased by 4 (in 802.3ac) for 802.1Q. Is there a further extension to frame size associated with QinQ? --Kvng (talk) 18:44, 6 March 2011 (UTC)[reply]

802.3 2008 describes an envelope frame, which allows up to 1982 octets for use of protocols such as 802.1ad, see sections 3.2.7 and 1.4.151. All 802.11q frames are considered envelope frames, not just 802.11ad. But, the original MAC Client data has not been expanded past the original 1500 octets, even if envelope formats are used. 26 August 2011 — Preceding unsigned comment added by 135.245.10.3 (talk) 21:33, 26 August 2011 (UTC)[reply]

802.1QinQ802.1ad — 802.1QinQ is not an 802.1 standard. See discussion above. Kvng (talk) 16:13, 30 March 2011 (UTC)[reply]

Obsolete Standard

[edit]

This standard is obsolete, as 802.1ad has been incorporated into 802.1Q-2011. See 802.1 wiki page, 802.1ad reference[1] — Preceding unsigned comment added by 135.245.48.12 (talk) 14:10, 21 March 2014 (UTC)[reply]

That's mentioned in the lead. The name of these amendments tend to live on past when they are incorporated. ~Kvng (talk) 03:26, 27 September 2024 (UTC)[reply]

Quoting from arctive: Just as QinQ extends 802.1Q, QinQ itself is extended by other Metro Ethernet protocols.[specify] i.e. PBB-TE can be named as a reference. — Preceding unsigned comment added by 2001:A60:1629:B201:7A24:AFFF:FE42:3EA5 (talk) 12:44, 30 January 2015 (UTC)[reply]
