Basic Configuration
• Authentication/Privacy: Configures the Authentication and Privacy features
for SNMPv3 communication. The Authentication / Privacy parameter offers two
options, which function as follows:
1. Auth/noPriv: An SNMPv3 username and password will be required at log in,
but encryption will not be used. (Default Setting.)
2. Auth/Priv: An SNMPv3 username and password will be required at log in, and
all messages will be sent using encryption.
Notes:
• The Authentication / Privacy item is not available when the Version parameter
is set to V1/V2.
• If the Version Parameter is set to V1/V2/V3 (all) and Authentication / Privacy
parameter is set to "Auth/Priv", then only V3 data will be encrypted.
• The VMR/NPS supports DES encryption, but does not currently support the
AES protocol.
• The VMR/NPS does not support "noAuth/noPriv" for SNMPv3 communication.
• SNMPv3UserName: Sets the User Name for SNMPv3. Note that this option is
not available when the Version parameter is set to V1/V2. (Default = undefined.)
• SNMPv3Password: Sets the password for SNMPv3. Note that this option is not
available when the Version parameter is set to V1/V2. (Default = undefined.)
• SNMPv3PasswordConfirm: This prompt is used to confirm the SNMPv3
password that was entered at the prompt above. Note that this option is not
available when the Version parameter is set to V1/V2. (Default = undefined.)
• AuthenticationProtocol: This parameter determines which authentication protocol
will be used. The VMR/NPS supports both MD5 and SHA1 authentication.
(Default = MD5.)
Notes:
• The Authentication Protocol that is selected for the VMR/NPS must match the
protocol that your SNMP client will use when querying the VMR/NPS unit.
• The Authentication Protocol option is not available when the Version
parameter is set to V1/V2
• SNMPContact: (Default = undefined.)
• SNMPLocation: (Default = undefined.)
• ReadOnlyCommunity: Note that this parameter is not available when the SNMP
Version is set to V3. (Default = Public.)
• Read/WriteCommunity: Note that this parameter is not available when the SNMP
Version is set to V3. (Default = Public.)
