13. Operation via SNMP
If SNMP Access Parameters have been defined as described in Section 6.8.5, 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 RPC unit,
and lists some common commands that can be employed to manage users, control
switching and reboot actions and display unit status.
13.1. RPC SNMP Agent
The RPC’s SNMP Agent supports various configuration, control, status and event
notification capabilities. Managed objects are described in WTI-MPC-VMR-MIB.txt,
which can be found in the user's guide archive on the WTI web site at:
The WTI-MPC-VMR-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
lack of support for encryption of transmitted data. SNMPv3 addresses both of these
For SNMPv3, the RPC 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 or AES (in the case of the SRM, the default encryption format for
SNMPv3 is DES.) For the Password protocol, the SRM supports either MD5 or SHA1.
