4-Port Ethernet Switch Module Firmware - IBM BladeCenter

Download Description

Note: Please see the README and CHANGE HISTORY files for complete details of the code upgrade and the complete change history.

Severity: Suggested

Version 1.09 (00.00.97) - ibmrun.097

• Multiple potential switch hang conditions have been identified and eliminated from the switch firmware.
• Fixed the diagnostic function for a TFTP (Trivial File Transfer Protocol) recover of a crash dump file into ibmesm_coredump.txt
  

Version 1.08 - ibmrun.096

• The blade port link detection firmware of the ESM has been enhanced to prevent a link flapping condition on empty blade positions. This condition was infrequently observed in a limited number of system hardware configurations.
• A condition that may occur when a switch is powered off with Redundant Switch Failover enabled and activated has been corrected. When re-powered, the blade ports sometimes would not be enabled even though the failover criteria of the external trunk up condition was satisfied. This firmware enables the ESM to always associate the link status with the failover criteria.
• The ESM now disconnects all telnet connections immediately after a reboot command is issued. Previously there was a delay before the disconnect.
• Queue management of the ESM was slightly adjusted in version 00.00.95 in an attempt to balance the packet drop associated with oversubscription of link bandwidth.
  The oversubscription queue management function of the ESM has been returned to the pre-95 settings.
• The ESM has improved handling of large frame pings directed to the CPU. A fix for fragmented Linux ping frames is also included.
• GVRP (GARP (Generic Attribute Registration Protocol) VLAN (Virtual LAN) Registration Protocol) has been adjusted to better conform to the IEEE Standard 802.1D, 1998 edition and the 802.1Q, 1998 edition.
• The enabling and disabling of trunk ports has been improved. The GUI interface will enable and disable individual trunk ports as a group. Prior to this change, when disabling an external trunk group, the GUI shows all member ports as disabled, however only the master port is disabled.
• Web up/down direction notation has been corrected. The Browser Download Configuration Menu opened to display Upload Configuration.
• Missing VLAN status has been corrected. In the Telnet console, the VLAN 12 status entry column was sometimes missing.

Version 1.07 - ibmrun.095

• Spanning Tree Protocol Port Cost now holds assigned fixed values. On previous releases the Cost assumed the default value for the speed of the link. Auto Port Costs are still available with v095. To select an Auto Port Cost enter a zero (0) value for the Port Cost.
• The ESM response to pings with large byte counts (64K max) was improved. Large byte count pings to the ESM will not effect the response of the management console interface.
• The capability to assign a static multicast router address to a port on a per VLAN basis has been added.
• ARP table learning has been enhanced for Spanning Tree configuration changes.
• ARP table learning has been enhanced for Failover configuration changes.
• SNMP fix for Ext-4 and block/unblock control, SNMP PVID on Ext-4 to enable configuring the port to access mode, and SNMP External port 'up' or 'down' status fix.

Version 1.06 - ibmrun.092

• The IBM MIB file posted with this release was updated on July 29, 2004.
• NOTIFICATION OF NEW FEATURE AVAILABILITY - Crash Dump. If the CPU of the ESM should crash, information will be saved to assist with debug. To recover the crash dump file containing the information perform the following:
  • 1. Start a TFTP server
  • 2. Restart the switch and begin a TELNET session to the ESM
  • 3. Under Utilities Select Upload Configuration File to TFTP Server
  • 4. Enter the TFTP server IP address
  • 5. Under Filename specify: ibmesm_coredump.txt, and TFTP upload.
  • 6. A text editor can be used to view the debug information.
• NOTIFICATION OF NEW FEATURE AVAILABILITY - Syslog. Events entered into the history log table of the ESM can also be sent to a server. Access to syslog messages requires:
  • 1. Start a syslog server (or syslog relay)
  • 2. Configure the server with a UDP port, the default value is 514.
  • 3. Syslog server IP address and UDP port are defined in the ESM web or telnet page of "Configuration->Syslog Configuration"
  • 4. Enable the 'syslog status' to start the messages.
• FIXES ADDRESSED in v092:
• Fixed NESSUS telnet issue.
• Fixed hang condition caused by multiple open TCP connections
• Fixed hang condition caused by improper address entered during TFTP.
• Updated Save Before Reboot message in Switch Interface.
• Updated VPD information to be independent of default configuration.
• SNMP updated with multiple fixes.

Version 1.05a - ibmrun.091 or ibmrun.081

• NOTIFICATION OF NEW FEATURE AVAILABILITY - REDUNDANT SWITCH FAILOVER
• "Redundant Switch Failover" is available in firmware version 1.05, ibmrun.091, which can be installed on ALL IBM BladeCenter 4-Port Ethernet Switch part numbers, (FRU PN 59P6620, 13N0557, and 26K6482).
• Note: As stated below, avoid use of "RESET TO FACTORY DEFAULT", if ibmrun.091 is installed on FRU PN 59P6620 and PN 13N0557.
• A new IBM BladeCenter 4-Port Ethernet Switch Module Installation and User's Guide is available as a web download. Refer to the Link Aggregation section.
• A change to the ESM assembly and FRU part number is the reason for the new firmware release, ibmrun.091.
• ibmrun.081 and ibmrun.091 are functionally the same with the following exceptions:
  • If "Reset to Factory Default" is executed, via the WEB Browser or Telnet interfaces, ibmrun.081 will write Asm P/N 13N0558 and FRU P/N 13N0557 to the VPD.
  • If "Reset to Factory Default" is executed, via the WEB Browser or Telnet interfaces, ibmrun.091 will write Asm P/N 26K6483 and FRU P/N 26K6482 to the VPD.
• The user should confirm the ESM FRU P/N via the MM WEB Browser Hardware VPD listing or inspection of the label on the ESM enclosure.
  • If the FRU Part Number is 26K6482, use ibmrun.091
  • If the FRU part number is 13N0557, use ibmrun.081
  • If the FRU Part Number is 59P6620, use ibmrun.081
    Note: For FRU PN 59P6620 do not use the "RESET TO FACTORY DEFAULT" option.
    
    

  Note: After file transfer and ESM Re-Boot is completed, via the MM Browser, initiate an ESM power cycle (off then on) to refresh the MM Hardware VPD data. An alternative is to remove and re-install the ESM. Verify, the expected ESM FRU and Assembly part numbers are displayed.

Version 1.04 - ibmrun.081

• SNMP Fixes for VLAN egress.
• Fix for web interface VLAN configuration with static trunking.

• Fix proprietary MIB and clean up SNMPv2 unimplemented branches.
• Drop packet from invalid Vlan.
• Remove the restriction which limited IGMP snooping, works with IPMC sender with src IP subnet equal to ESM's IP subnet.
• Fix a problem which causes the switch to completely hang up.
• Fix POST failure while using ESM HW version B1 (This is the FPGA Grant line fail problem).

Version 1.01 - ibmrun.062

• Fixed ping fail after VLAN configuration issue.
