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.

Protocol	Security	Authentication	Data	Method
Version	Mode	Type	Encryption
	V1, V2c	Community		Use a community string match
	Read		No
		string		for authentication
