New Features: - IPv6 long prefix - TACACS + user level assign - DDM Fixes: - Fixed: The switch will prompt "% Invalid interface" when entering "ipv router rip" in VLAN interface. - SSH session will be closed when DGS-6600 is attacked by hydra tool, a dictionary interface. - DGS-6600 OSPF state is unstable after DGS-6600 is rebooted an re-learn a lot of IPv6 routes(e.g. more than 4000 entries of RIPng routes) at the same time. - When DGS-6600 IGMP snooping is disabled but received IGMP packets(sent by DGS-1210), the FDB address learning maybe incorrect, causing PC ping DGS-1210 management IP failed. - When creating ACL command but using "cursor left" key to add parameter, it will cause DGS-6600 to parse the command as an ambiguous result. - After assigning VLAN-trunk (4k VLAN entries) to the specified interfaces, it will spend more than 30 minutes if user resets the device to default configuration. After improvement, it takes 7.5 minutes to complete it. - Due to memory resource constraint, DGS-6600 limits the maximum number of ports which can be added in VLAN to 4094 VLANs x 96 ports (which is 393,024) but it does not limit in "port channel". - DGS-6600 re-calculates OSPF routing table every 10 seconds, causing network to be unstable. - DHCP relay function will stop running when DGS-6600 receives invalid header with DHCP packet.
