Rackswitch G8052 Firmware version 7.6.3.20 (released October 2013)
** Changes since the 7.6.3.10 release **

Enhancements:
None.

Changes:
None.


Fixes:
- Inefficiencies in the SNMP-processing code could result in high CPU
  utilization, SNMP client time-outs, protocol flaps, or a switch reset
  by the Hardware Watchdog.
   (66769, 70649)

- A crash would occur when routing packets to an unreachable IPv6 gateway.
   (68081)

- A watchdog timeout could occur if an IGMPv3 Report packet was
  received with the invalid source-IP address of 0.0.0.0.
   (71749)

- BGP neighborship sessions would flap when receiving BGP route messages
  that contained community attributes
   (XB194426)

- A crash could occur while handling an HTTPS request if the connection
  to the client was suddenly terminated while handling the transaction.
   (XB205895)

- The ACL logging feature would not report incoming packets that
  matched an ACL qualified by a TCP or UDP destination port.
   (XB208108)

- A crash would occur if a data port was used to upload a file to an
  FTP server, if the file already existed on the server and had 
  read-only access permissions. 
   (XB209257)

- A crash would occur if the traceroute command was executed with an
  IPv6 address specified, and no IPv6 management interfaces were configured.
   (XB215717)

- A crash would occur if a ping was issued to a random host name,
  and an IPv6 DNS server was unreachable or non-existent
  (XB216882)

- A crash would occur during a second attempt to authenticate a user
  via an unreachable or non-existent LDAP server.
   (XB217674)

- A crash would occur if a TFTP upload or download was attempted,
  and no IPv6 interfaces were configured.
   (XB218041)

- The switch's Browser-based Interface (BBI) was vulnerable to attacks
  by Web scanning tools, potentially resulting in crashes.
   (XB218795)

- A crash would occur when receiving a random sequence of IGMPv3 reports
  that were interleaved from different Multicast receivers.
   (XB219263)

- Invalid TCP packets (e.g., having both SYN and FIN flags set) received
  by the switch would not be discarded, resulting in a potential security
  vulnerability.

===================================================================================
Rackswith G8052 Firmware version 7.6.1.0 (released December 2012)

New and Updated Features 
========================

BGP Route Reflection:
---------------------
Route Reflection is a technique to avoid a large number of sessions between IBGP
peers. In this release, support for RFC4456 (BGP Route Reflection - An Alternative
to Full Mesh Internal BGP (IBGP)) has been added.


SNMP: Support for 8 Read-Only and Read-Write communities:
---------------------------------------------------------
This release adds support for 8 read-community names(Read-Only),
and 8 write-community names(Read-Write) with SNMPv1 and SNMPv2.


RFC5340: OSPF For IPv6:
-----------------------
The switch was previously compliant with RFC2740. Starting with this release,
the switch is compliant with RFC5340, which supersedes RFC2740.


NTP Client Display Improvements:
---------------------------------
The Network Time Protocol (NTP) is widely used to synchronize computer clocks
in the Internet.  With the NTP service enabled, the switch can accurately
update its internal clock to be consistent with other devices on the network. 

In this release, the "show ntp" command has been updated with such details as
clock offset, stratum, and reference clock.  Also in this release is a dampening
of the number of syslog messages generated when the system clock is updated or
if NTP synchronization fails.


Cisco-like CLI:
---------------
As part of this change, some existing ISCLI commands have been modified to look
more like those in Cisco's IOS.  The commands chosen for modification in this
release are ones frequently used for VLAN, Port, and STP configuration.
With these changes, those familiar with Cisco-IOS CLI can more readily configure
the IBM-NOS VLAN, Port, and STP modules.
