Please note that this posting is incorrect.
Foundry's release notes ver. 7.1.09, which is
the release notes for the FastIron II family
(FastIron II and FastIron IIPlus) and the
BigIron family (BigIron 4000 and 8000),
stated that this problem is "FIXED" in 7.1.09
and NOT a bug. For the ServerIron family,
release 7.1.06 fixes this problem.
This statement
"If you entered a very long string when
prompted for a Telnet password, then
pressed Enter before the software timed out
the access attempt, the device reset."
is within the "Software Fixes" section (p. 191),
which itemizes fixes current and earlier
software releases.
Please contact your local Foundry Sales
Representative or Engineer for details.
Thanks. Val Oliva
