I've seen this on 7603/Sup720 with 12.2(18)SXE2. Which is a router we
can open TAC cases for :-)
TAC response was that this is CSCsa77158: "Router stops accepting SSH
IPv6 connections, IPv4 SSH still works", and that this is only in 12.2SXE,
and "already fixed in a more recent 12.2S version". So YMMV.
The bug toolkit does not list any fixed-version at all, and *especially*
doesn't list any IOS versions that are not 12.2SX* - so the information
given is certainly not complete.
If you can open a TAC case, it would make sense to point them to this
bug, and explain "we're affected, too, go and fix it"...
("That's what they get from inventing a bazillion loosely-related
USENET is *not* the non-clickable part of WWW!
