----------------------------


New Features in Version 3.2.2


SAND Version 3.4.2 Included

ImageStream's SAND Version 3.4.2 release is included in the Version 3.2.2
release.  See the release notes for Version 3.4.2 for more information about the
SAND Version 3.4.2 software release.  This SAND release adds support for the
WANic 520 series DS-3 and E-3 cards.


Interface Statistics Utility Updated

Version 3.4.2 of SAND includes an updates statistics utility ("stats").  This
utility adds several new features and corrects several bugs.  See the Version
3.4.2 release notes for more information.  The stats utility supports CSU/DSU
statistics, reports link status and configuration information for Ethernet, and
adds several new usability features.


Menu System Prompts For Reload Of Common Services

Common tasks that support reloading without stopping the service first, such as
Network Interface Configuration, now prompt users from the menu when exiting a
configuration file. Version 3.2.2 will no longer automatically reload these
common services.


Zebra Dynamic Routing Option Added

A package using version 0.92a of the Zebra dynamic routing software has been
added to Version 3.2.2.  The option to configure and use Zebra has been added to
the Configuration and Update menu under Dynamic Routing Configuration.  Zebra
supports BGPv4, OSPFv2, RIPv1 and RIPv2.  Zebra's BGP implementation includes
support for community strings.  gated is still available as the default dynamic
routing option for Enterprise Linux.


Hardware Status Utility Added

Version 3.2.2 includes a complete hardware health monitoring package.  Users
with newer routers with SMBus (Intel PIIX4) and I2C chipsets can now check
temperature, voltage and fan speed from the Advanced menu.



Removed 127-character Limit From menuEngine Commands

The version of menuEngine supplied with Version 3.2.2 supports additional
flexibility in reloading and error-checking from the router menu.  Previous
versions limited command strings to 127 characters.


Memory Test Boot Option Updated

Version 3.2.2 updates the "Memory test" option in the router boot menu.
Selecting this option from the boot menu will load a memory testing program that
automatically examines the RAM installed in the router for any physical problems
or errors.  A thorough memory test may take several hours to complete, so this
boot option is recommended for use during maintenance windows and for routers
able to be removed from service for long periods of time.  The memory test
utility included with Version 3.2.2 has been updated to the latest available
version to support new memory architectures.

Bugs fixed in Version 3.2.2


The following bugs have been fixed in Version 3.2.2:


Unused Libraries And Terminal Type Definitions Removed

Version 3.2.2 removes several unnecessary and unused libraries from the
distribution.  Additionally, unused terminal type definitions have been removed
from /usr/lib.  The following terminal types are supported by Enterprise Linux:
linux, vt100, vt102, vt220, ansi, ibm327x, xterm, wy50 (Wyse 50), wy60 (Wyse
60), sun, and screen.  The "unknown" default terminal type is also supported.
The removal of these libraries and terminal definitions increases the space
available for new features and user-defined programs.


Fixed Startup Error Message About Kernel Modules

Version 3.2.2 adds a comment to /etc/modules.conf to supress a boot-time message
about the file being empty.  /etc/modules.conf is unused in the default
configuration and is provided only for user-defined module support.


Missing Quit Options Added

The Save Configuration To Flash and Revert Router To Factory Defaults menus now
have Quit options.  These options were not present in previous versions.  The
"No" option can still be used to exit the menu.


Missing Bonder Configuration Option Added To Default stats.conf File

Previous versions of Enterprise Linux did not exclude Bonder interfaces from the
non-SAND interface configuration file in /etc/stats.conf.  A "noshow" option has
been added to the default file in Version 3.2.2.  This corrects an error where
stats would not display traffic statistics for Bonder devices.


Various Aesthetic Changes To Menu Options

Version 3.2.0 fixes small typographical errors in two of the Advanced router
menu scripts, adds clearer descriptions of several menu items, and adds a
separate Dynamic Routing configuration menu.

Limitations and Upgrade Instructions


*** NOTE! If the upgrade fails, do NOT reboot! Contact ImageStream's
Technical Support without rebooting. ***


Limitations

Upgrading to Version 3.0 or later requires the following:

1. 64 MB of RAM or higher.
2. 32 MB of flash.
3. 300 MHz processor or better.
3. Enterprise Linux Version 2.3.2 or higher.

The upgrade utility will not install Version 3.0 if memory and flash
requirements are not met.  Users can contact ImageStream to purchase a
RAM, processor or flash upgrade.

Users running an Enterprise Linux version less than 2.3.2 must upgrade
before Version 3.0 will be available from the Update menu.  Upgrading any
version prior to 2.3.2 will automatically be upgraded to 2.3.2.  A second
upgrade will be required to install Version 3.0.

The upgrade does not otherwise affect the stored configuration in the
ImageStream router. To back up the router's configuration prior to
upgrading, choose option 4 (Backup/Restore) from the router's main menu.
Choose the Backup methods option (Option 1) and select a method from the
choices listed.  From the router's command line, use the "backup"
command. The backup utility takes four arguments: flash (to back up
configurations to the router's nonvolatile flash memory), floppy (to back up to
a floppy disk), scp (to back up via secure copy), or file (to back up to a
separate file on the router's nonvolatile flash memory).
