SNMP-NV6
Page 30
If you use a workstation with SNMP Manager installed, or if you set more restrictive SNMP
access, you can use the SNMP Access to add the IP address of the PC, which you use to
modify the access permission. If the IP address is set as 0.0.0.0, it means the IP address will
be ignored. The SNMP-NV6 card will check the community string first to identify whether the
incoming packet is Read Only or not.
5.5.2 SNMPv3 USM (User Based Management)
SNMPv3 is an encryption version of SNMP protocol. Before you can access the SNMP OID
from the SNMP-NV6 card using SNMPv3 protocol you have to configure the SNMPv3 USM
table.
There can be 8 SNMPv3 users for the SNMP-NV6 card. After configuring the account
parameters you can access the card using SNMPv3 protocol. This user table is related to the
SNMPv3 Trap.
To test the SNMPv3, find a Linux operating system and open the terminal shell then key in
the following command to get the reply:
snmpwalk -v 3 -u <user> -l authPriv -A <password> -X <password> -n <context name> -
t 3 <ip> 1.3.6.1.2.1.1.1.0
Where:
-v: 1 for SNMPv1, 2 for SNMPv2c, 3 for SNMPv3.
-l: Follow the security level, there are noAuthNoPriv, authNoPriv and authPriv.
-u: The user name, which is assigned in the SNMPv3 USM table.
-A: Follow an Auth Password, which is assigned in the SNMPv3 USM table.
-X: Follow a Priv Password, which is assigned in the SNMPv3 USM table.
-n: The Context Name, which is assigned in the SNMPv3 USM table.
-t: Timeout in second.
<ip>: IP address of the SNMP-NV6 card.
<oid>: The available SNMP OID, please refer to the MIB file. For example: 1.3.6.1.2.1.1.1.0
