FIRMWARE CHANGE HISTORY
-----------------------

IBM Flex System Interconnect Fabric version 7.8.8.0 (Released November 2014)
** Changes since the 7.8.7.0 release **

Enhancements:

LACP Individual Mode
--------------------
When this feature is enabled on an LACP port-channel, if a member port of the port-channel
does not receive any LACPDU over a period of time, it will be treated as a normal port 
which may forward data traffic according to its STP state.


Changes:
none

Fixes:

- FCoE sessions could flap due to the High CPU Utilization caused by the software
  flooding of Clear Virtual Links packets with an unknown destination MAC in the FCoE VLAN.  
  (LV296464)

- Configuration changes could be denied with the error "Error: STP cannot be enabled on 
  FC port <port number>.",  if any vlan assigned to a fiber channel port is a member of 
  a MSTP instance.
  (X294677)

================================================================================
IBM Flex System Interconnect Fabric version 7.8.7.0 (Released September 2014)
** Changes since the 7.8.6.0 release **


Enhancements:
none

Changes:
none

Fixes:

- Ports INTB1 & INTB2 would be disabled, when CMM failover occurs due to loss of 
  physical connectivity on the active CMM link.
  (XB172285)

- CMM could incorrectly report the switch to be offline for about 30 seconds at 
  boot up, after failing to query switch information. A notificatin 
  "communication offline" shows up on the CMM UI during this time, and is cleared 
  once the CMM establishes communication to the switch.
  (XB268099)

- Fixed OpenSSL vulnerabilities as reported in CVE Advisories CVE-2014-3505, 
  CVE-2014-3506, CVE-2014-3507, CVE-2014-3508, CVE-2014-3509,CVE-2014-3510, 
  CVE-2014-3511.
  (XB293143)

- FCOE sessions would flap at random and the message "Could not read FC module 
  temperature" would be logged due to deadlock on the I2C bus shared between 
  Ehternet and Fiber Channel modules.
  (XB281638)

- Receive FCS Errors would be reported on ports EXT1 and EXT2 when using 7m or 
  longer passive DAC cables due to incorrect firmware settings.The "Receive FCS Error 
  Frame Counter" would increase on these ports. 
  (XB280713)

- Changes to configuration are denied with the error "Error: Ports x and y have 
  the same LACP admin key but different link settings (speed/duplex/flowcontrol).", 
  when links x and y with dissimilar cables (i.e DAC and SFP+) are aggregated.
  (XB282364)

- All FCOE FIP solicitation messages were tied to the lowest numbered port in the NPV 
  Vlan, even when no FCF ports were online in the NPV Vlan.
  (XB290563)

- A crash would occur after multiple failed attempts to login via SSH or BBI, if 
  secure-backdoor is enabled and the configured remote RADIUS/TACACS authentication
  servers can be reached  . 
  (XB293746,XB292790)

- Secure-backdoor access to the switch  fails via SSH, when configured remote 
  RADIUS/TACACS authentication servers can be reached.
  (XB293743,XB294261)

- Secure-backdoor and backdoor access to the switch via SSH, fails to prompt 
  for username.
  (XB292116,XB293076)

- Saved IP Gateway configuration is lost upon reload or upon issuing "copy" commands 
  when associated IP interface is deleted.
  (XB274331)

- A crash would occur when hotlinks active interface is disabled and enabled in quick 
  succession.
  (XB278024)

- Executing "copy tech-support" family of commands could result in instability in the 
  stack and cause FCOE sessions to flap.
  (XB274963,XB274963)

- The internal/external controlled ports from all units other than the master remain 
  down  post reload, in a L2 Failover AMON/MMON scenario.
  (XB275310,XB277583,XB277982)

- Changes to configuration are denied with the error "Error Ports ... have  the same 
  LACP admin key but different STP edge settings" after a non-existing VLAN is added 
  to a port , if LACP and STP edge/portfast are both enabled on the port.
  (XB282083)
