1. Support for the “Hunt Group” protocol (Smarttrunking) mode of port trunking was removed. Port
trunking is still supported. All trunking protocol selections were removed from the Trunking
Configuration Menu.
2. Changing port names via Cabletron WebView would not be saved to non-volatile memory. --This has
been fixed.
3. When connecting with Telnet from Sun Solaris 2.6, 2.7 and Red Hat Linux 5.2 and 6.0 into the switch,
extra asterisk (*) characters were displayed and each password character was echoed back. This has
been fixed.
4. Port mirroring options have been changed so that transmit and receive can now be set to yes/no
independently. Both can now be enabled at the same time; this was not possible in previous firmware
versions.
5. A new feature has been added to the Spanning Tree configuration screen in the user interface: menu
item “h. Spanning Tree Standby Enable”, which has allowable settings of YES or NO. The default
setting is YES. With this setting there is a 30-second forwarding delay time. If set to NO, all ports will
go into forwarding mode within approximately one second (Fast Port). This setting can be used to
avoid timeouts (with resulting failure to connect) at workstations directly attached to the switch. Note
that this setting affects all ports, and can not be set on an individual port basis.
The Spanning Tree Standby configuration option has also been added to the Web-Based
Management, and can be found in the Switch Configuration, then Spanning Tree Configuration
menus.
Note: A new MIB object has been added to the Cabletron Proprietary MIB, and is described here as a
supplement to Table 5-2 in the Installation and User Guide:
Variable Description
SwitchSpanningTreeStandby Globally enable/disable Spanning Tree Standby on the switch.
6. A change has been made which will prevent a mis-configuration of Port Mirroring. Port mirroring mis-
configuration causes the feature to be enabled in the hardware although the configuration screen
indicates it is disabled. A mis-configuration occurs when the mirrored port and mirroring port are
selected from two different clusters.
7. A verification prompt was added to eliminate the danger of accidentally enabling port mirroring. The
prompt is displayed if the current state of port mirroring is disabled and the user presses the “F” key to
enable port mirroring on the configuration menu.
8. Using Netscape Navigator for Web management had problems when the “reload” command was
invoked. This has been fixed.
9. When configuring VLANs, the user could not assign specific VLAN IDs. This has been fixed.
10. The dot1qNextFreeLocalVlanIndex should return “0”. This has been fixed.
11. A new feature has been added, whereby the switch will save all configuration information to non-
volatile memory before a TFTP file transfer request is processed.
12. A change has been made whereby the default is for diagnostic testing to be OFF. Diagnostics can be
enabled through the user interface: select System Configuration, then Power Up Diagnostics to toggle
between YES (enabled) and No (disabled).
13. SNMP Interface Index values were incorrectly returning the wrong port numbers (it would return Port
Number +1). – This has been fixed.
14. Fixed Spanning Tree bug: According to 802.1d, right after a topology change, root should use shorter
aging timeout (forward delay) instead of 5 minutes. It should use this timeout for (forward delay + max
age).
15. A bug that allowed system MAC addresses to be improperly aged out, causing loss of TCP/IP
connections, had previously existed. -- This has been fixed.
