DXS-3350SR /DXS-3326GSR Firmware Release Note  
Firmware: 4.40-B04
Hardware: A1/A2/A3
Date: Aug. 31, 2006

Problems Resolved:
1.	Fix static MAC address will be filtered when the "port lock" value in port security function = 0.
2.	Fix device cannot get IP from DHCP server after rebooting the device even the DHCP configuration has been saved.
3.	Fix the IGMP Snooping does not work "under jumbo IPMC data environment" issue.
4.	Fix the PIM-SM "static RP" configuration will be lost after saving the configuration and reboot the device.
5.	Fix DHCP relay function failed when stack master ID is not 1.
6.	Fix LACP configuration across stack will fail after "reset system" and hot insert new box type of device.
7.	Fix PC ping device will fail when there is SFP port's I2C component broken in the device.
8.	Fix the device will show ping success even if received the reply with TTL expired.

Enhancements:
1.	Enlarge the maximum RP support of PIM-SM from 10 to 40.
2.	Add the MAC address format "AABBCCDDEEFF" support in the WEB UI.


Firmware: 4.30-B11
Hardware: A1/A2/A3
Date: Apr. 12, 2006

Problems Resolved:
1.	Fix the problem when IP forwarding database is full, "show ipfdb" command cannot show information correctly.
2.	Add an error checking mechanism when configuring “Port mirroring across stack” in Web UI. "Port mirroring across stack" is not supported.

Enhancements:
1. PIM-SM (single domain support)
2. Port Mirroring - ACL mode
3. Configurable RIP timer
4. Support extra 7 types (MX, NS, CNAME, AAAA, TXT, SOA, ANY) for DNS-Relay (Without cache and static function.)
5. Add one new log message when device detect damaged Mini GBIC inserted into SFP ports, Switch will point out the damaged port number in the log message for user debugging.

===========================================================

Firmware: 4.20-B11
Hardware: A1 & A2
Date: Dec 29, 2005

Problems Resolved:
1. Fix the problem when user configures SNTP and then click SNMP page in Web UI, the device will be entering exception mode.
2. Fix the problem when using "show config in NVRAM" command in CLI and "Save configuration" command in Web UI at the same time, the device will be entering exception mode.
3. Fix the problem when Switch receives lots of UDP broadcast packets (Dest. Port=3000) continuously, the whole Switch stack will reboot.
4. While showing the existing ACL rules in Web UI, the port information will be different as what user just configured, though it does operate as users configured.
5. Fix when "Static ARP" is configured by SNMP, it can't be deleted by CLI even reset system to default.
6. Improve the convergence time in RSTP mode.
7. Fix the problem when user forced the unit stacking ID = 1 but it's not stacking master, the port LED will become solid green and Switch will stop forwarding packets.
8. Fix the problem if user deletes one or some IP interfaces then reboot the system, the MAC address of IP interfaces will be changed.
9. Fix the security issues recently reported for unauthorized system access.

Enhancements:
1. CPU Interface Filtering (Software ACL)
2. Support non-IE browser (Netscape, Firefox, Opera, Mozilla)
3. Support remote upgrade of prom code
4. Add DEM-420CX(2-port CX4 Module) support
5. Support ACL auto-assign and portlist in SNMP interface
6. Limit the access by passwords generated by "D-Link PWD calculator". Before, if customers forgot their configured passwords, D-Link could generate passwords based on the MAC addresses provided by customers via D-Link HQ maintained PWD calculator. Thus customers can use those "backdoor" passwords via telnet/ web/ console to logon to their switch again. Now the access of those passwords generated by "D-Link PWD calculator" will be limited to console access only. This is to minimize the security concern.

Note: This is a recommended security patch for your customers.
