February 10, 2023: Version 1.0.1.00
- Resolved Issues:
1) Fixed an issue where communication of terminals that failed step authentication could not be blocked.
2) Fixed a problem that communication breakdown occurs when SSH connection is repeatedly continued to be executed.
3) Fixed a problem that "SSH Key verify error" may be displayed and connection may be refused when receiving a specific SSH connection request packet.
4) Fixed a problem that SSH connection may be disconnected while getting Log by SSH.
5) Fixed a problem in which packets with Checksum field of 0x0000 in ICMP messages were received but not responded.


April 6, 2022:  Version 1.0.0.05
- Specification Changes:
1) System log / SNMP trap issuance delay time setting command.
 logtrap linkchange delay <0-30>

- Resolved Issues:
1) Despite that the connection condition of LLDP neighbor device is not changed,the log of "LLDP-MED Topology change detected" may become recorded.
2) If the RRP route-change occurs, the communication is not  transferred to some IP addresses.
   If this failure occurs in the firmware version, which is earlier than 1.0.0.04, relearning ARP allows the communication to be transferred.
3) Disconnections may occur if our device receives the specific HTTP communication when enabling the WEB authentication function. 
4) The link-down rarely occurs. 


August 30, 2021:  Version 1.0.0.04
- Add New Function:
1) We added the egress-buffer control command on the date.      
(For details, see the instruction manual of this product.)    

- Specification change:
1) We improved the threshold of the egress-buffer on the date.  
2) We changed the initial value of the power-saving Ethernet (EEE) to disabled on the date. 

- Resolved Issues:
1) If you configure two or more RRP domains to change one status of the RRP domain to "disabled", other RRP domains do not operate (or work) normally. 
2) The configuration of lldp management-address is not reflected.
3) The VLAN1 settings is not displayed in a configuration. 
4) The loop detection and blocking (or shut-off) function may operate on the port, where the link-aggregation is configured during the boot-up.
5) You cannot specify the firmware for a boot-file from an SD card, on a WEB configuration interface.
6) Regarding the configuration file, which is saved into the main unit by copying the content of an SD card on the WEB settings screen, the file cannot be specified as the boot-up file.
7) If you create a large quantity of VLANs, you need the necessary time for saving the configurations.
8) If you change the interface VLAN mode after configuring a ring-protocol, the status of the ring-protocol becomes "Fail" and then a loop occurs. 
9)  Failure to configure lldp management-address, which is saved when you reboot.
10) After turning on the power, monitoring the temperature cannot be normally detected. Because of this event, TEMP LED keeps flashing.
