32. Fixed that DGS-3200 does not save VLAN settings if VLAN trunking is used.
33. Fixed that the configuration of JWAC auth_failover cannot be saved. It lost
after reboot the switch. (DI20100315000006)
34. Fixed that "enable WAC function" does not saved after reboot.
35. Fixed that when MAC-based access control and STP functions are enabled
on the same port, BPDU was blocked and dropped by MAC-based access
control function. STP does not work on the port and traffic storm is
occurred. (DI20100422000003)
36. Fixed that Safeguard engine cannot be disabled. (DRU20100527000001)
37. Fixed that it needs to create an account "enable" onto TACACS+ server
database with new password. (DRU20100602000001)
38. Fixed that DGS-3200 TFTP UDP 69 port is opened by default, even though
the associated used function SIM is disabled. (DUSA20100617000001)
39. Fixed that if two or more DGS-3200 are cascaded and DHCP relay are
enabled in all DGS-3200, DHCP client (DGS-3200) in down linked unit
cannot obtain the IP address from DHCP server. (DRU20100707000004)

DGS-3200 Series Firmware Release Notes
1. Client could still access the network when the configured JWAC idle timeout
is reached. JWAC will now correctly age out the client after the configured
idle time expires.(DI20090406000008)
V1.50.B019 2. After a client connected to DGS-3200 successfully passes 802.1X NAP
authentication, an error log (event ID 6275) appears in the NPS server.
A 802.1X Accounting attribute “NAS-Port-Type (61): Ethernet (15)” has
been added to fix this problem. (DI20090325000019)
1. VLAN advertisement packet will not be sent if GVRP is not enabled on the
client ports. (DI20080411000016)
2. Multicast groups entries are not deleted while the switch is in non-querier
state and enable fast leave. (DI20080527000009)
3. The switch will not forward the group specific query to the client ports while
client sends a IGMP leave message to querier switch.
4. There will be packets loss if the switch receives massive amount of IGMPv3
reports to join the same multicast group address. (DI20080514000007)
5. Fixed the performance issue while show current_config by using telnet and
SSH. (DI20080625000018)
6. When data-driven multicast is enabled if client join/leave multicast groups
repeatedly, unknown multicast group will not be forwarded to router port.
7. In 802.1X host-based access control, after a client successfully
authenticates, moves to another port then move back which the ports
cascaded by hub. There will be no authentication even the authentication
status is “authenticated”. (DI20080626000014)
8. The querier switch does not send IGMPv3 membership query message,
therefore, multicast group will timeout by default 260 seconds.
(DI20080707000023 )
v1.35.B023 9. If serial number is not burned in the flash but the firmware supports the
display of “serial number” on the switch, it will be displayed as scrambled
code. Fixed the problem that there will be no serial number column if the
switch doesn’t burn-in serial number.(DUSA20080709000001)
10. While enable MAC-based Access Control by local database, one client
connects to a port with a downlink unmanaged switch, another client
connects to the switch directly, only latest client who authenticated success
will pass.(DI20080813000012)
11. Incorrect authenticating state in MAC-based access control of web-GUI
even no user is authenticating on that port. (DI20080818000011)
12. An incorrect message will pop up if user deletes IGMP snooping groups VID
1. (DI20081014000019)
13. While enable RSTP and LACP application, the convergence will take around
3 minutes. (DI20081104000004)
14. The “new line” symbol (0D0A) is inconsistent in configuration file.
15. “Save all” configuration page cannot display in Firefox 3 browser on
FreeBSD7.1 OS. (DI20081105000023)
16. The switch will enter exception mode while using openSSH5.1 to logon the
switch. (DI20081105000022)
17. CPU utilization will go up to 100% if multiple users login via SSH.

DGS-3200 Series Firmware Release Notes
18. While enable RSTP, SA of BPDU is always system MAC, the duplicate MAC
cannot be learned on different ports and cause system IPIF no reply.
1. While auto configuration is enabled, if DHCP server and TFTP server are in
the same server, download configure will fail. (DI20081120000010)
2. There are two local3 facility parameters of syslog setting in web-GUI,
which should be local4 facility. (DI20081208000009)
3. All ports will become discarding designated status when MSTP is enabled.
v1.35.B023 4. “config scheduling 7” does not appear in configuration file.
5. When MAC-based access control is enabled on port1, client can pass
authentication, however, if the same client moves to port 8, which does not
have MAC-based access control enabled, client will be blocked.
v1.11.B004 None
1. The switch console freezes if changing any STP-related configuration (e.g.,
enable/disable STP ports, or reset configure).
2. The MST ID can not be configured correctly by WEB UI.
3. While one port leaves MLD snooping group, it will cause other ports to
leave the group automatically.
4. Add the parameter “replace_DSCP ” on ACL profile Ethernet, IP, Packet
content mask and IPv6.
5. The switch can not add entry for IP-MAC-Binding via D-View module.
6. Single IP Management: The Commander switch with D-Link WEB GUI 1.0
can not manage SIM members with new D-Link WEB GUI 2.0.
7. The IP-MAC-Binding entry is created via SNMP even when MAC and port
information are not provided.
8. When the “forward_unregeisted_group” is enabled, if one PC joins the
group, the other PC connected with DGS-3200 can still receive the
non-join mutlicast group data.
v1.11.B003 9. The client can not join MLD v2 group by using ‘filter exclude null IP source’
and can not leave group by using filter include null IP source.
10. A MLD v2 client can not leave a group if other group member keeps
sending join packet.
11. The NDP packets can not pass through DGS-3200-10 while
“filter_unregistered_group” is enabled.
12. Switch only sends one Robustness control packet when the switch receives
leave packet, no matter what Robustness value has been set, either the
switch is in querier or non-querier state.
13. The entry of MLD snooping table is not deleted even the client sends leave
14. When receiving group specific query, the switch duplicates one extra query
packet to its VLAN member ports.
15. The switch does not delete the entry of the IGMP snooping table, even it
has received IGMP leave packets from clients.

DGS-3200 Series Firmware Release Notes
16. Inconsistent GVRP information between Web-GUI and CLI. When the client
disables VLAN advertisement under CLI or Telnet, it will show ‘enable’ on
17. The switch can not flood router advertisement, neighbor advertisement or
IPv6 PIM to all ports of the VLAN, when the switch learned router port in
IPv6 environment.
18. If the client sends IGMP snooping/MLD snooping join packet first then the
switch learns a router port, the switch will not flood the multicast traffic to
router port.
v1.11.B003 19. While SSH server is enabled on DGS-3200-10, telnet client can not work.
20. The switch can not add 2nd and 3rd RADIUS servers.
21. When using MAC-based Access Control to authenticate a client, the switch
does not assign correct VLAN to the client even when it is successfully
22. Fix head of line blocking problem. If there are too many broadcast,
multicast or unknown traffics, the packet will be lost.
23. Change "cold-start" to “warm-start” in SNMP.
v1.00.B015 First release
* D-Link tracking number is enclosed in ()

Known Issues:
1. The incorrect report will be learned to IGMP table.
2. IGMP leave message will affect different groups.
3. Cannot configure limited multicast address range with the same name of
the created profile.
4. Data driven learning table cannot update after deleting the multicast filter
5. Limited multicast address range cannot block multicast group correctly.
6. DGS-3200-16 fiber port LED will be still displayed if the fiber of combo port
