13. Operation via SNMP

If SNMP Access Parameters have been defined as described in Section 5.9.6, then you will be able to manage user accounts, control power and reboot switching and display unit status via SNMP. This section describes SNMP communication with the MPC unit, and lists some common commands that can be employed to manage users, control switching and reboot actions and display unit status.

13.1. MPC SNMP Agent

The MPC’s SNMP Agent supports various configuration, control, status and event notification capabilities. Managed objects are described in the WTI-MPC-MIB.txt document, which can be found on the CDROM included with the MPC unit, or in the user's guide archive on the WTI web site (http://www.wti.com/manuals.htm).

The WTI-MPC-MIB.txt document can be compiled for use with your SNMP client.

13.2. SNMPv3 Authentication and Encryption

The major limitations of SNMPv2 were the failure to include proper username/password login credentials (v2 only used a password type of login, i.e., community name) and the exclusion of encryption for data moving over the internet. SNMPv3 addresses both of these shortcomings.

For SNMPv3, the MPC supports two forms of Authentication/Privacy: Auth/noPriv which requires a username/password, but does not encrypt data going over the internet and Auth/Priv which requires a username/password AND encrypts the data going over the internet using DES (AES is not supported at this time). For the Password protocol, the MPC supports either MD5 or SHA1.
