                            2: About This Release
===============================================================================

This release of the SuperStack II Switch 1100 / Switch 3300 management software
supersedes the previous versions of software. It adds a number of new commands 
to the CLI and fixes some minor problems. 

The New Commands
----------------
To use the new commands, just follow the prompts displayed when you access the 
CLI. Note the unique capitalization of the displayed commands. Below the 
commands are shown all in capital letters to distinguish them from common text.
However commands must be entered in lower case.

Limitation : The input is restricted to 80 characters only.

A new top-level command for the administration of SNMP functions has been 
introduced - SNMP. Under this you will find:

    COMMUNITY    sets the SNMP community string
    GET          gets SNMP objects
    NEXT         gets the next SNMP object(s)
    SET          sets SNMP objects
    TRAP         administers SNMP trap destinations using -
                     DEFINE      defines a new trap destination
                     DISPLAY     displays all trap destinations
                     MODIFY      modifies a trap destination
                     REMOVE      removes a trap destination


An additional command for the administration of security is found under 
SYSTEM - SECURITY. Under this you will find: 

    USER - from which you may:
           DEFINE       defines a new user
           DISPLAY      displays all users
           MODIFY       modifies a user
           REMOVE       removes a user
    ACCESS - from which you may:
           DISPLAY      displays access rights
           MODIFY       modifies access rights

Additional commands for the administration of ports are found under ETHERNET -
    AUTONEGOTIATION  enables / disables autonegotiation
    FLOW CONTROL     enables / disables flow control (for full duplex only!)
    PORT MODE        sets the port speed and duplex mode

Bug Fixes
---------

1) The Switch would wrongly transmit ICMP error messages in response to IP broadcasts in a different subnet.

2) CLI port statistics for non-unicast traffic are now correctly shown.

3) When a resilient link switched from main to standby or vice versa, it would continue to send traffic to the failing link, causing a loss of communication.

4) Enabling "Port Based Security" using a web browser now works correctly.

                            3: Upgrading the Software
===============================================================================

The management software can be upgraded by using a TFTP Server or by using the
Management Software Upgrade Utility supplied with your Switch.

- To upgrade your software using a TFTP Server, you need to place the file s2s01_07.bin 
  in the appropriate directory on the server. 

  Note: 3Com provides a DOS-based TFTP Server on the 3Com Bulletin Board. For
  information on how to use the Server, refer to the file 3comtftp.txt that is
  supplied with it.

- To upgrade your software via the serial link using the Management Software Upgrade Utility, 
  you need to place the file s2s01_07.bin in a directory accessible by the PC running the utility. 
  For more information, refer to the User Guide supplied with your Switch.
