Subject: (ANNC) Enterprise Linux 2.3.2 for ImageStream routers available

Version 2.3.2 of ImageStream's Enterprise Linux is now available as a
general release for all ImageStream router customers.  Version 2.3.2 is a
maintenance release.

This software release is provided at no charge to all ImageStream
customers, and is recommended for all customers who wish to upgrade to the
latest available software release.

This release note documents commands and features added between Version
2.3.1 and Version 2.3.2. 


New Features in Version 2.3.2

Update Script Supports New Upgrade/Downgrade Selection

The automated update script has been modified to allow greater flexibility
during the update process.  The script now supports pre- and post- update
modifications.  Version 2.3.2 allows users to select a software release
from a menu.  Users can upgrade or downgrade their distribution as needed. 

Support for WANic 561E, 562E, and Maxim 564

Version 3.27 of SAND, included in Version 2.3.2, supports the new WANic
561E and 562E single- and dual-port E1 CSU cards.  Support for the Maxim
564 front and rear I/O versions has been added as of Version 3.27. 


Bugs fixed in Version 2.3.2

The following bugs have been fixed in Version 2.3.2: 

Transmitter Timeout Error On WANic 600 and 800 Series Cards Corrected

Under heavy traffic loads, especially with bonded interfaces, the WANic
600 and 800 series cards could experience transmitter timeouts.  Ports
affected would stop transmitting data until reset or until the traffic
load decreased.  Version 3.27 corrects this behavior. 

Default Firewall Script Modified

The main firewall script in the router distribution has been modified. 
Access to gii, the Gated Interactive Interface for dynamic routing, is
limited by default to access only from localhost.  Previous distributions
allowed telnet access by default. 


Upgrade Instructions

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

The upgrade process on an ImageStream router erases the operating system
software area from nonvolatile memory. Never interrupt the upgrade
process, or loss of software information can result.

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
