Fixed field issues:
1. Fixed the issue that user name is not displayed on system log when saving the configuration via SNMP.
2. Fixed the issue that, in some circumstances, when user logs in and enters an incorrect password which is longer than the correct password, user can still be allowed to login.
3. Fixed the issue when user changes the telnet port number and save it, the telnet port number will be change back to default port number 23 after switch reboots.
4. Fixed the issue when user sets the 802.1X RADIUS Timeout to 30 seconds, switch will only send the RADIUS request in the first 10 seconds and then times out.
5. Fixed the issue when the port speed was set fixed (e.g., 10_half, 100_half), the port cannot link up if using straight cable to connect two devices.
6. Fix the issue when using SNMP to get "ifHighSpeed", the display value is incorrect.
7. Fix the issue that DES-3000 series learns illegal SA MAC address (00-00-00-00-00-00) in the ARP table.
8. Fixed the issue when user creates static FDB at port1 and set port security max learning address 0 at port 1 at the same time, the switch’s log still displays Port Security Violation log at port1.
9. Fixed the issue when creating the CPU interface filter to permit IP1 and deny all, PC with IP1 can ping the switch; however, after the PC executes "arp -d", the PC cannot ping the switch anymore until the switch reboots.
10. Fixed the issue If 802.1X re-authentication were triggered in PC, the switch should reassign attribute according to policies in RADIUS server.
11. Fixed VLAN entry not displaying port information in the web GUI.
12. Fixed the firmware download problem that when using Linux Firefox, the firmware download process status cannot be displayed.
13. Fixed the display direction issue of VLAN portlist from left to right.
14. Fixed the firmware downgrade issue which all ports will go link down after downgrading.
15. Fixed the issue that users are unable to set the gateway IP address to 10.255.255.1
16. Fixed the issue that session table displays incorrectly after auto refresh in show session command.
17. Fixed the issue when login as administrator to execute the “save” command, the log will display user name as “Admin” instead of correct user name “manageadmin”.
18. Fixed the issue that IGMP v2 membership query packet will be blocked when 802.1X is enabled.
19. Fixed the issue that after configuring multicast filter mode "Forword_unregister_ groups", the multicast stream will flood to the port which has not yet been authenticated.
20. Fixed the issue that when running some test scripts like repeating telnet or uploading config test, sometimes device may not be manageable.
