Re: Proposed Liaison response on Ethernet Jumbo Frames

Alia –

Regarding

“The ISIS Working Group will discuss whether there is additional work to do now that IEEE Std 802.1AC-2016 is available.”

Did we not discuss this on the list and determined there is no work??

Hi,

At the end of the ISIS WG meeting at IETF 98, I called attention to the recent liaison from IEEE -  https://datatracker.ietf.org/liaison/1509/<https://datatracker.ietf.org/liaison/1509/>.  There was significant concern expressed about the decision to use a new EtherType instead of EtherType 88-70, which is widely deployed.

Here is a proposed liaison response, which should also update you on progress that has been made in this area. I would prefer to get this liaison, with any improvements, agreed to by June 15.

=========
Colleagues,

Thank you very much for your liaison on March 25.  We are happy to learn that IEEE now has a standard, IEEE Std 802.1AC-2016, for encoding LLC frames and that its use appears to be exactly as described in draft-ietf-isis-ext-eth-01.  There are a large number of pre-standard implementations and deployments of this functionality.

With informal discussion, we were able to determine the current owner of EtherType 88-70 and have what we believe is the necessary statement so that this EtherType is now available for this functionality.  I would like to thank both Yaakov Stein, CTO RAD, for making this happen and David Aviv, CTO Radware.  As these types of challenges come up and have large impact, we would prefer to learn of them earlier so that we can try and assist sooner in the process.

We are quite concerned about the allocation of a new EtherType given the extremely large deployment of this pre-standard common feature.  We would encourage the IEEE 802.1 Working Group to strongly consider updating IEEE Std 802.1AC to use the deployed EtherType 88-70 that is now available for this purpose.

The ISIS Working Group will discuss whether there is additional work to do now that IEEE Std 802.1AC-2016 is available.

Warmest regards,
Alia Atlas, IETF Routing Area Director
Chris Hopps, ISIS Working Group Chair
Hannes Gredler, ISIS Working Group Chair

Please also discuss whether there is additional ISIS work to be done.  I'm specifically thinking about sending hello packets at the MTU.

Regards,
Alia
