Configuring NMIS8 for SNMPv3

Prerequisites

To use SNMP version 3 NMIS requires two perl modules that are not normally or automatically installed, Crypt::DES and Digest::HMAC.
From version 8.5.14 onwards the installer will try to install these modules; until then you'll have to resolve this dependency by hand:

• on Debian or Ubuntu use: sudo apt-get install libcrypt-des-perl libdigest-hmac-perl
• on RedHat/CentOS use: sudo yum install perl-Digest-HMAC perl-Crypt-DES
• or, if neither option appeals you may also use CPAN: sudo  cpan Crypt::DES Digest::HMAC.

Change Nodes.nmis Configuration

You can edit a Node using the NMIS GUI to include support for SNMPv3, as described in Adding and Editing a Device in NMIS8, you can also edit the Nodes.nmis file to set the details.

You will need to modify the NMIS8 configuration to use SNMPv3, the user name, protocols and passwords need to match the above IOS configuration.
