Re: [savi] Gen-ART review of draft-ietf-savi-threat-scope-06

Would it suffice to replace
Old:
   If the bridging topologies which connects the switches changes, or
   if LACP [IEEE802.3ad] changes which links are used to deliver
   traffic, the switch may need to move the SAVI state to a different
   port, are the state may need to be moved or reestablished on a
   different switch.
New:
   If the bridging topologies which connects the switches changes, or
   if LACP [IEEE802.3ad], VRRP, or other link management
   operations, change which links are used to deliver
   traffic, the switch may need to move the SAVI state to a different
   port, are the state may need to be moved or reestablished on a
   different switch.
?

Proposed changes on the second - fourth lines above.
Yours,
Joel

Ted,

Remembering that this is an informational draft, which does a pretty good job
of informing the reader about the problem space, is it your opinion that the
issues you have raised _must_ be addressed before the document is published,
or do you think the document is still valuable even if no further text is
added to address your concern?

At a minimum, in section 4.1.2, this should be addressed:

b) the new text implies that LACP is the only way to cause this situation - it's
        not, so LACP should be used as an example.

I'm not sure I've seen Fred's response, but that change would suffice.  An RFC
Editor note should suffice.

Thanks,

Summary: This draft is on the right track, but has open issues, described in
the review.

While I identified the same issue you did with switching systems that do link
aggregation and other magic, I think that the document is useful whether this
is fixed or not.  It's true that it doesn't have a full section that talks
specifically about this problem, but I think it's unlikely that the authors
are going to add one-when I mentioned it to Joel, he didn't express excitement
at the prospect.

I think Fred's response, while a little salty, accurately represents the
situation: the working group produced this document, the document does what
it's supposed to do, one could continue to polish it indefinitely, but then
the document would never get published.
