Re: [IPFIX] Fwd: New Version Notification fordraft-kashima-ipfix-data-link-layer-monitoring-05

Hi Shingo San,
I think this would be very useful to include in the draft. We have been
working on this but didn't get to put it in a draft. Glad you could put
them in here.
I have some comments about the draft.
1) 
3.6.  dot1qServiceInstanceTag
Maybe this could be reworded to:
      This Information Element, which may have 16 octets length,
represents 
      the Backbone Service Instance Tag (I-TAG) Tag Control Information
      (TCI) field of an Ethernet frame as described in
      [IEEE802.1ah-2008]. It encodes the priority, drop_eligible,
destination
      and source address.  
2) It looks like Section 3.7 and 3.8 have got interchanged. The
description and the information elements have been switched.

3) Could we include a section that would say the current and new
information elements needed to export all the 802.1ah header fields like
so:

This is a summary of the 802.1ah fields and the new and current
informational elements that would be used to represent each of the
fields.

Very sorry about what happened in Japan, it is very unfortunate.
My best wishes, please take care,

Dear all,

Here is a new version of the draft, which includes:
- new information elements related to 802.1ah (MAC-in-MAC)

Is this valuable for WG item ?
