Corrections (from 2.3.2)
· Fixed some corner cases for port-based VLAN application.
· Fixed crash caused by nmap task.
· Fixed a page-misalign problem in the Multicast page in the Web.
· Fixed a bug, which caused telnet to fail sometimes.
· Limited the length of an URL to 255 characters in the Web server.

Enhancements (from 2.3.2)
· Add IEEE 802.1w (Rapid Spanning Tree Protocol) support. The default mode for STP changed from IEEE 802.1d to IEEE 802.1w.
· Add support for EAP-TLS and EAP-TTLS for 802.1x Port Authentication.
· Add support for RADIUS accounting.
· Add support to allow range of IP address in host IP filter table or SNMP host table.
· Change the firmware upgrade procedure in Net-Save mode that the firmware will be downloaded and saved to the on-board Flash before the switch is rebooted. This solved the problem of upgrade failure when using fiber GBIC.
· Add a new control in SNMP access to allow read access to any host.
· Change SNMP read access from blocked to allowed by all hosts as default.

Installation Procedure (also located in your documentation)
1. Put the new software image on a PC with TFTP server. The file should be in the TFTP home/root directory.
2. Go to Main Menu > Tools > Software Upgrade (in the Web or Console Interface).
3. Select ‘Net’ option for ‘Next Boot from’ field.
4. Verify information such as the IP address for the TFTP Server, Gateway IP address, and the file name and its path of the new image (no path is needed if the file is under TFTP root directory)
5. Save the setting in non-volatile memory before reboot. In the Browser interface, go to Main Menu > Tools > Save Configuration, and use the ‘Save’ button. In the console interface, use Ctrl-W and confirm the change to NVRAM.
6. Restart the system via the Tools > Reset command. Bootstrap will retrieve the new image then pass control to it. The system will execute the new software image.
7. Test your switch to make sure the new image is working correctly. If you decide to keep the new image, go to Software Download again. Select ‘Net & Save’ option in ‘Next Boot from:’ field. If you prefer the previous firmware, just reboot your switch.
8. Restart the system via the Tools > Reset command. The new image should over-write the old image in non-volatile memory.
9. Verify the new image by going to the Main Menu > System and check the ‘Software Version’ information.
