Management Access Security
The EPICenter Inventory Manager can discover SNMPv3 devices in your enterprise network. Click on
the Discover button to set the discovery options for building an inventory of your network. Select the
SNMPv3 discovery checkbox to add SNMPv3-enabled devices to your inventory.
You can also add a device to the Inventory Manager, manually entering the SNMPv3 settings for the
device. This includes the authentication and privacy settings for SNMPv3 and the passwords.
Figure 46 shows an example of adding an SNMPv3 device that uses CBC DES privacy and SHA
authentication protocols.
Figure 46: Adding an SNMPv3 Device to Inventory Manager
The top level display for the Inventory Manager shows all the device groups configured in your
network. Select a device group to determine what SNMP version is configured for each device in that
group.
If you change the contact password or SNMP community string, EPICenter will ask if you want to
change these settings on the device as well as in the EPICenter database. If you choose not to change
the settings on the device, you will need to configure them manually on each device before EPICenter
will be able to access them. If you change the SNMPv3 settings, you will also need to Telnet to the
device and change those settings locally.
You could use a Telnet Macro in the EPICenter Telnet feature to configure SNMPv1 or SNMPv3 on a
series of devices. For example, if you wanted to migrate multiple devices from SNMPv1 to SNMPv3,
follow these steps:
1 Configure a Telnet Macro on all the devices to set up SNMPv3 and run the macro.
2 Use Modify Device across those same devices to change EPICenter to use SNMPv3. EPICenter
allows you to modify multiple devices at the same time.
