- DHCP Relay option 60 & 61
- RSPAN (Remote Switched Port Analyzer) support: Can monitor and analyze the traffic passing through the ports in another switch.
- IGMP Snooping supports Data Driven Learning so the switch will build up the entry in its multicast table when sniffing the multicast traffic from the media server. Typically used in an environment where the multicast server is connected to the switch directly.
- Route redistribution: allows routers on the network, which are running different routing protocols to exchange routing information.
- Enlarge MAC Base Access Control local DB to 1024.
- Add traffic control “countdown” parameter: Timer for shutdown mode (only supported in CLI).
- Update sFlow version from 1.00 (IPv4) to V5 (IPv6).
- Add digital signature in D-View module.
- Via SNMP, the counter value of the port will be 0 when the port is linked down
- When user logins via JWAC and continuously moves client PC on different ports, the switch session table will be full, and then the PC can not get IP address from the DHCP Server. User can see the log "JWAC enters stop learning state".
- After user links up/links down one port on DGS-3400, the SNMP host can not receive SNMP trap about link change from DGS-3400.
- Rebooting the slave stacking unit while JWAC authentication from clients are undertaken will cause the slave unit to show “Device Discovery” after its rebooting.
- DGS-3400 does not erase IGMP Snooping entries for LAG port
- DGS-3400 does not erase MLD Snooping entries for LAG
- Some stacking units are unstable when IMPB and DHCP snooping are enabled
- Some clients’ IP addresses are not written to "binding_entry" table when 12 GDS-3400 are in a stack with IMPB and DHCP Snooping enabled.
- DGS-3400 does not flood IPv6 control packets when MLD Snooping is enabled.
- When Topology Change has occurred on the LAG port over stacking units, DGS-3400 sends many SNMP traps and Syslog packets which are related to RSTP Topology change.
- JWAC Customized Page displays error after saving and rebooting the switch
- DGS-3426 may enter exception mode when configuring some SNMP commands
- Clients cannot be authenticated by JWAC, because DGS-3400 JWAC does not respond to the VLAN-tagged packets.
- If the SNMP manager sends "SNMP get request" about "ifNumber: 0" to DGS-3400, the value of response is incorrect.
- High CPU utilization issue: When LACP runs across stacking units (total two stacking units),
- powering off the master unit will make LACP re-run and it needs around 5-7 seconds to recover.
- High CPU utilization issue: After powering on the Master and reconnecting the Master back to the
- stack topology, the LACP will lose traffic around 1.7 second.
- High CPU utilization issue: The DGS-3400 CPU utilization is up to 100% when receiving a lot of
- broadcast traffic.
- Device will send out the RADIUS packets with NAS-Identifier not as"D-Link".
- The character in last line of uploaded configuration file is not 0x0D0A
- When using WindowsXP with window size 80*25 to telnet the device and then execute "show config", some command characters are missing if the command length is longer than 80.
- DGS-3400 series can not recognize Cisco STP packets thus STP port role and status are not changed when DGS-3400 is connected to a Cisco Switch
- Some MAC addresses are recorded as "BlockByMACAuth" even though these MACs are already authorized by MAC Base Access Control (MAC)feature as "Authenticated".
- When STP is enabled, DGS-3400 CPU utilization becomes 100% after unplugging and plugging the port connection between the stack master and slave.
- DGS-3400 CPU becomes high utilization when cleaning the IMPB entry
- When powering off/on a stacking member unit, the STP topology was changed and the stacking unit is sometimes in loop condition for a while.

  It is highly recommended to always use the most recent driver version available.

Try to set a system restore point before installing a device driver. This will help if you installed an incorrect or mismatched driver. Problems can arise when your hardware device is too old or not supported any longer.
