The engine ID can be specified by entering 10 to 64 hexadecimal characters. If less than 26 characters are specified, trailing zeroes are added to the value. For example, the value “1234” is equivalent to “1234” followed by 60 zeroes.

Web – Click SNMP, SNMPv3, Remote Engine ID. Enter an ID of up to 64 hexadecimal characters and then click Save.

Configuring SNMPv3 Users

Each SNMPv3 user is defined by a unique name. Users must be configured with a specific security level and assigned to a group. The SNMPv3 group restricts users to a specific read, write, or notify view.

Command Attributes

•User Name – The name of user connecting to the SNMP agent. (Range: 1-32 characters)

•Group Name – The name of the SNMP group to which the user is assigned. (Range: 1-32 characters)

•Security Model – The user security model; SNMP v1, v2c or v3.

•Security Level – The security level used for the user:

-noAuthNoPriv – There is no authentication or encryption used in SNMP communications. (This is the default for SNMPv3.)

-AuthNoPriv – SNMP communications use authentication, but the data is not encrypted (only available for the SNMPv3 security model).
