EDS-408A/405A Series User’s Manual Featured Functions

The Factory Default function is included to give users a quick way of restoring the EDS’s
configuration settings to their factory default values. This function can be accessed from either the
telnet/RS-232 Console, or Web Browser interface.
NOTE After activating the Factory Default function, you must use the default network settings to
re-establish a web-browser or Telnet connection with your MOXA EtherDevice Switch.
Configuring SNMP EDS switches support SNMP protocol. The available versions are SNMP V1, SNMP V2c, and
SNMP V3. SNMP V1 and SNMP V2c use a community string match for authentication, which
means SNMP servers access all objects with read-only or read/write permissions using the
community string public/private (default value). SNMP V3, which requires you to select an
authentication level of MD5 or SHA, is the most secure protocol. You can also enable data
encryption to enhance data security.
SNMP security modes and security levels supported by the EDS are shown in the following table.
Select the security mode and level that will be used to communicate between the SNMP agent and
manager.
