1.0 ABOUT THIS README FILE
__________________________

This file is intended for network administrators responsible for
upgrading the firmware for the Nortel Networks Layer 2/3 Gigabit
Ethernet Switch Module (GbESM).

For a summary of GbESM features, supplemental information and 
known issues associated with this release, please refer to the 
"Release Notes - Layer 2-3 GbE Switch Module for IBM eServer
 BladeCenter", available via web sites indicated in section 6.1.


2.0 CHANGE HISTORY
__________________


Version 1.2.3.11 (Released May 2006)

 
 Fixes:

 - Corrected a condition where Tagged Bridge Protocol Data Units (BPDU's)
   were being transmitted on ports that did not have tagging enabled.
   A port With a sole Virtual Local Area Network (VLAN) Spanning Tree
   Group (STG) other than 1, would transmit tagged BPDUs. (fix number 4702)

 - Corrected a condition where Rapid Spanning Tree Protocol (RSTP) in 
   Forwarding state was causing a Link Aggregation Control Protocol (LACP)
   loop.  Two ports at layer 2 physical interfaces forward and both ports
   indicating they are the root port for spanning tree, producing a
   connection drop. Link Aggregation (LAG) may be up but physical
   interfaces are dormant. (fix number 6307)

 - Corrected a condition where /info/log Log did not record time/date 
   changes from the Brower-Based Interface (BBI). (fix number 5402)

 - Tightened restriction to prevent a user from upgrading with a
   firmware file intended for a different switch type. (fix number 4702)

 - (Related fix) FTPing an invalid image initially posted a message saying 
   image is invalid, but then the message timed out and the Command Line
   Interface (CLI) returned.  

 - Corrected a condition where NNCLI (Nortel Networks CLI) 
   Secure Shell (SSH) ON/OFF configuration was not working.  
   Command worked in Operating System (OS) mode, but not NNCLI.
   (fix number 5821)

 - Corrected a condition in the BBI, where if a Management Network and Mask 
   such as 10.0.0.0,and 255.0.0.0, is changed to all zeros, the subnet mask 
   would remain unchanged. CLI works OK.  (fix number 4782)

 Enhancements:
	
 - BladeHarmony Manager (TM), which provides a graphical user interface
   supporting remote management of the GbESM through Simple Network
   Management Protocol (SNMP) has been introduced in conjunction with
   this release. 

   Refer to the "Using BladeHarmony Manager 1.0" document for details.


Version 1.2.2.0 (Released January 2006)

 Fix: 
 - Fixed flooding for unregistered multicast packets,
   and for IGMP snooping disabled VLANs. 


Version 1.2.1.0 (Released January 2006)

 Enhancements: 
 - Added "industry standard" CLI (NNCLI) mode 


Version 1.1.1.1 (Released October 2005)

 Fixes:
 - General IGMP cleanup

 Enhancements:
 - L2 Trunk Failover improvements (VLAN-based, static or LACP trunks,
   more trigger options)
 - Number of allowable trunk groups increased to 13
 - Support for trunking INT ports from same blade
 - Available Spanning Tree Groups increased to 32
 - Maximum VLANs supported increased to 1024
 - Management feature improvements (logging/alarm/alert suppression)
 - Software upgrade via HTTP (i.e. browser)
 - Support end-to-end Flow Control using 802.3 Pause Frame protocol
 - Ability to tag Native VLAN (PVID) traffic


Version 1.0.1.6 (Released June 2005)

 Fixes:
 - No tagged PVST BPDUs in the native VLAN if associated STP is off
 - Tagged BPDU's not being forwarded
 - IGMP becomes non-functioning after reboot
 - Inaccurate link values/states returned via SNMP
 - Forwarding Data Base (FDB) not flushed when the last link in trunk
   goes down
 - Ports transitioning from STP Forwarding to Blocked states are not
   flushed from the IGMP table
 - Cannot delete a static Multicast Router port
 - CLI misreporting high MP utilization
 - Changing link type in BBI not reflected in CLI
 - Virtual Router GUI not posting VRs correctly in BBI DASHBOARD mode


Version 1.0.1.1 (January 2005)
 - Initial Release.



3.0 INSTALLATION AND SETUP INSTRUCTIONS
_______________________________________

The GbESM firmware is composed of two (2) code images: the boot
code and the switch operating system.  The GbE switch module ships
with this firmware pre-installed. However, new versions of the
firmware are periodically released and can be used to update the
features and function of the switch.


3.1 Software update procedure
-----------------------------

Update the switch software using a TFTP or FTP server
application. Typically, this application is installed on a
machine that is reachable from the switch through the external
ports or the management module.

NOTES:
     - The following steps reflect the use of a TFTP server.
       A FTP server can also be used.

     - Upgrades can also be performed using external ports. Please
       see "Externally managing the GbE switch module" in the
       GbESM Installation Guide.

1) Download the GbESM software package (zip file) to the machine
   where the TFTP server resides.

2) Extract the Boot and OS image files into a directory. Enable
   the server and set its default directory to the one where the
   image files reside.

3) Establish a connection between the Ethernet port of the
   BladeCenter Management Module and the TFTP Server.

4) Using the Management Module web interface (GUI), configure the
   IP Address/Mask of the Management Module External (eth0) and
   Internal (eth1) interfaces, the GbESM switch and the TFTP server
   so that they all reside on the same subnet.

    For example,

        Management Module (eth0) => 192.168.70.125 / 255.255.255.0

        Management Module (eth1) => 192.168.70.126 / 255.255.255.0

        GbESM Current IP Config  => 192.168.70.127 / 255.255.255.0

        TFTP Server              => 192.168.70.254 / 255.255.255.0

     NOTE: Although configured as such, for this example, the 
           TFTP Server does not have to be on the same subnet as
           long as a proper gateway address is configured in the
           switch.


 3.1.1 Using Telnet
 ------------------

 1) Using the Management Module GUI, navigate to:

    I/O Module Tasks -> Configuration -> Bay X ->
               Advanced Configuration -> Start Telnet session
    
    When the telnet session is established, you will begin using
    the Command Line Interface (CLI) of the GbE switch.

 2) Enter "admin" for the password.

    The GbE switch provides storage for two (2) OS images and
    one (1) Boot image. What you are about to do consists of the
    following sequence:

     - load the new OS image into one of the image banks
     - reset the switch
     - load the Boot image
     - reset the switch

     NOTE: When you reset the switch it boots using the 'selected'
           image (1 or 2). Please ensure that you are booting from
           the upgraded image (execute /boot/cur to determine).

 3) Upgrade the OS image by entering the following commands:

    a) /boot/gtimg X TADDR GbESM-AOS-1.2.3.11_OS.img

       WHERE:
       ------
           X  => 1 or 2 (depends which image bank you want to use)
       TADDR  => IP Address of the TFTP Server
 
       NOTE: It is recommended that you retain the previous OS
             version by loading the upgrade into the other image
             bank and then reset the switch using the new image.
             (use /boot/image command to select preferred image)

       Answer 'Y' to the confirmation question, then wait for the 
       upgrade to complete successfully.
 
    b) /boot/reset

       NOTE: You MUST Reset the switch to activate the new image.
             Resetting the switch kicks you out of the CLI, so
             Steps 1 and 2 need to be executed again before
             proceeding to the next step.
             A switch reset completes in approximately 60 seconds.

 4) Upgrade the Boot image by entering the following commands:

    a) /boot/gtimg boot TADDR GbESM-AOS-1.2.3.11_Boot.img

       Answer 'Y' to the confirmation question, then wait for the 
       upgrade to complete successfully.

    b) /boot/reset


 3.1.2 Using BBI
 ---------------

 1) Using the Management Module GUI, navigate to:

    I/O Module Tasks -> Configuration -> Bay X ->
               Advanced Configuration -> Start Web session
    
 2) Enter "admin" for the username and 'admin' for the password.

 3) Click the CONFIGURE button (near top of page)

 4) In the frame on the left, click on the "Nortel Networks
    Layer 2-3 GbE" folder icon and navigate to:

    System -> Config/Image Control

    The GbE switch provides storage for two (2) OS images and
    one (1) Boot image. What you are about to do consists of the
    following sequence:

     - load the new OS image into one of the image banks
     - reset the switch
     - load the Boot image
     - reset the switch

     NOTE: When you reset the switch it boots using the 'selected'
           image (1 or 2). Please ensure that you are booting from
           the upgraded image (see "Next Boot Image Selection" field).

 5) Upgrade the OS image as follows:

    a) Fill in the following three (3) fields on the lower half of
       the page:

       Hostname or IP Address of FTP/TFTP server => <server_addr>
       Image Filename => GbESM-AOS-1.2.3.11_OS.img
       Image for Transfer => 1 or 2 (i.e. the preferred image bank)

       NOTE: It is recommended that you retain the previous OS
             version by loading the upgrade into the other image
             bank and then reset the switch using the new image.
             (use the "Next Boot Image Selection" field to select
             the preferred image).

    b) Click the "Get Image" button.

       Wait for the upgrade to complete successfully.

    c) Click the "REBOOT!" button to reset the switch.
                                                        
       NOTE: You MUST Reset the switch to activate the new image.
             Resetting the switch kicks you out of the BBI, so
             Steps 1-4 need to be executed again before proceeding
             to the next step.
             A switch reset completes in approximately 60 seconds.

 6) Upgrade the Boot image as follows:

    a) Fill in the following three (3) fields on the lower half of
       the page:

       Hostname or IP Address of FTP/TFTP server => <server_addr>
       Image Filename => GbESM-AOS-1.2.3.11_Boot.img
       Image for Transfer => boot

    b) Click the "Get Image" button.

       Wait for the upgrade to complete successfully.

    c) Click the "REBOOT!" button to reset the switch.
                                                        

3.2 How to check the firmware version
-------------------------------------

To check the version of the firmware images installed on the GbESM,
use either of the following methods:

 a) From the CLI, execute the command:

    /boot/cur

    This command displays:

    Currently set to boot software image1, active config block.
    Current FLASH software:
      image1: version 1.2.3.11, downloaded 0:09:17 Mon May 08, 2006
      image2: version 1.2.2,    downloaded 0:08:48 Thu Jan 30, 2006
      boot kernel: version 1.2.3.11

 b) Using the Management Module GUI, navigate to:
    
      Monitors -> Firmware VPD

    Scroll down to view the VPD info for the appropriate GbE Switch.
    You should see the following entries:


    FIRMWARE TYPE             BUILD ID   RELEASED    REVISION
    -------------             --------   --------    --------

    Boot ROM                  WMZ03011   12/22/2005    0102
    Main Application 1(or 2)  WMZ03011   12/22/2005    0102

    
    The four digits comprising the version (e.g. 1.2.3.11) correlate
    to the REVISION/BUILD ID as follows:

    - Revision => 01 02 ... the first 2 digits of the version
    - Build ID => 03 011 ... the last 2 digits of the version
