Basic Configuration
5.9.6. SNMP Access Parameters
These menus are used to select access parameters for the SNMP feature. The SNMP
Access Parameters Menu allows the following parameters to be defined:
Notes:
• After you have configured SNMP Access Parameters, you will then be able to
manage the VMR/NPS's User Directory and display unit status via SNMP, as
described in Section 13.
• In the Text Interface, SNMP Access Parameters are defined via two separate
menus that are accessed via either the /N command (IPv4) or the /N6
command (IPv6.)
• In the Web Browser interface, both IPv4 and IPv6 SNMP Access Parameters
are defined via a single menu. When defining IPv6 parameters, make certain
that the IPv6 checkbox in the SNMP Access Parameters menu is checked.
• Enable: Enables/disables SNMP Polling. (Default = Off.)
Note: This item only applies to external SNMP polling of the VMR/NPS; it does
not effect the ability of the VMR/NPS to send SNMP traps.
• Version: Determines which SNMP Version the VMR/NPS will respond to. For
example, if this item is set to V3, then clients who attempt to contact the VMR/NPS
using SNMPv2 will not be allowed to connect. (Default = V1/V2 Only.)
• ReadOnly: Enables/Disables the "Read Only Mode", which controls the ability to
access configuration functions and invoke switching commands. When Enabled
("Yes"), you will not be able to change configuration parameters or invoke other
commands when you contact the VMR/NPS via SNMP. (Default = No.)
Note: In order to define user names for the VMR/NPS via your SNMP client, the
Read Only feature must be disabled. When the Read Only feature is enabled,
you will not be able to issue configuration commands to the VMR/NPS unit via
SNMP.
• 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.
