New Features in Version 2.3.1


Support For WANic/Aries/Maxim 564, 1000, and 1050         
 
Version 3.26 of SAND supports the 4-port integrated CSU/DSU card based    
on the 520 series chipset.  Version 3.26 also adds support for 1000 series
ATM OC-3 cards and 1050 series ATM DS-3/E-3 cards.

Beta Support For T1/E1 Multiplexing

The SAND architecture now supports multiplexing of T1 and E1 interfaces on
the 654 and 658 series cards.  Up to 127 total hardware subinterfaces can
be created per card in the system.  Support for this feature is BETA ONLY 
and does have known limitations that will be fixed prior to full release.
Customers requiring this functionality should contact ImageStream Support
by e-mail at support@imagestream.com for further guidance.

Bugs fixed in Version 2.3.1


The following bugs have been fixed in Version 2.3.1:


Transmit Timeout Error On Busy Links Corrected

Beginning with Version 3.25 of SAND, all protocol subinterfaces were
automatically bandwidth limited based on their master interface speed.
Under heavy traffic loads, if ports filled all of their buffers, a
"Transmit timeout" error resulted.  Version 3.26 correctly clears the
buffers on subinterfaces under heavy trafic loads.  Version 3.26 is
included in Enterprise Linux 2.3.1.

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
memory).
