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

Enhancements:
1. Increased the maximum RP support of PIM-SM from 10 to 40.

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

Problems Resolved:
1. Fixed the problem when IP forwarding database is full, "show ipfdb" command does not show information correctly.
2. Added 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. Added 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. Fixed the problem when user configures SNTP and then click SNMP page in Web UI, the device will be entering exception mode.
2. Fixed 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. Fixed 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. Fixed when "Static ARP" is configured by SNMP, it can't be deleted by CLI even reset system to default.
6. Improved the convergence time in RSTP mode.
7. Fixed 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. Fixed the problem if user deletes one or some IP interfaces then reboot the system, the MAC address of IP interfaces will be changed.
9. Fixed the security issues recently reported for unauthorized system access.

Enhancements:
1. CPU Interface Filtering (Software ACL).
2. Support for non-IE browsers (Netscape, Firefox, Opera, Mozilla).
3. Support remote upgrade of prom code.
