Using SNMP

EDS supports three SNMP protocols. The available protocols 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 EDS are shown in the following table. Select one 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
SNMP	Community
V1, V2c
	V1, V2c	Community	No	Use a community string match
	Write/Read
		string		for authentication
	Community
	No-Auth	No	No	Use account with admin or
				user to access objects
				Provides authentication based
	MD5 or			on HMAC-MD5, or
		MD5 or SHA	No	HMAC-SHA algorithms.
	SHA			8-character passwords are the
SNMP				minimum requirement for
				authentication.

				Provides authentication based
				on HMAC-MD5 or
	MD5 or		Data	HMAC-SHA algorithms, and
		MD5 or SHA		data encryption key.
	SHA		encryption key	8-character passwords and a
				data encryption key are the
				minimum requirements for
