Fixes: - Fixed the problem of switch not able to obtain IP address from some DHCP server. This particular DHCP server requires the source address from the DHCP discovery packet to be 0.0.0.0. - Fixed the problem that excess VoIP traffics with Auto-VoIP enabled could cause the switch to reboot or making the WEB GUI inaccessible after some period of time. - Fixed the problem that the switch still sends out RADIUS accounting packet even when port authentication fails. - Fixed the problem that the switch does not try to obtain time from SNTP server anymore if the SNTP server is rebooted. When this happens, status of "Kiss of Death" is shown in the "Last Attempt Status" column of SNTP Server Status under System > Management > Time > SNTP Server Configuration page. - Fixed the issue of network converging time is too slow with RSTP. When RSTP is enabled in a looped network, it still took more than 30 seconds to recover once the active forwarding link is disconnected. - Fixed the problem of not able to download configuration file successfully using SNMP (eg. setting MIB object agentTransferDownloadDataType to 3). - Changed default setting of Auto-VoIP (Switching > Auto-VoIP > Auto-VoIP) from enable to disable.
