Basic Configuration
5.9.6. SNMP Access Parameters
These menus are used to select access parameters for the SNMP feature. The SNMP
Access Parameters menus allow the following parameters to be defined:
Note: After you have configured SNMP Access Parameters, you will then be
able to manage the AFS-16's User Directory and display unit status via SNMP, as
described in Section 13.
• Enable: Enables/disables SNMP Polling. (Default = Off.)
Note: This item only applies to external SNMP polling of the AFS-16; it does
not effect the ability of the AFS-16 to send SNMP traps.
• Version: This parameter determines which SNMP Version the AFS-16 will respond
to. For example, if this item is set to V3, then clients who attempt to contact the
AFS-16 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,
you will not be able to change configuration parameters or invoke other commands
when you contact the AFS-16 via SNMP. (Default = No.)
Note: In order to define user names for the AFS-16 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 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 AFS-16 supports DES encryption, but does not currently support the AES
protocol.
• The AFS-16 does not support "noAuth/noPriv" for SNMPv3 communication.
• SNMPv3 User Name: Sets the User Name for SNMPv3. Note that this option is
not available when the Version parameter is set to V1/V2. (Default = undefined.)
• SNMPv3 Password: Sets the password for SNMPv3. Note that this option is not
available when the Version parameter is set to V1/V2. (Default = undefined.)
• SNMPv3 Password Confirm: 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.)
