snmp-ups \- Multi\-MIB Driver for SNMP UPS equipment
.SH"NOTE"
.sp
This man page only documents the hardware\-specific features of the snmp\-ups driver\&. For information about the core driver, see \fBnutupsdrv\fR(8)\&.
.SH"SUPPORTED HARDWARE"
.sp
The snmp\-ups driver automatically detects and supports a wide range of devices by loading various MIBS: \fBietf\fR:: UPS that is RFC 1628 (UPS MIB) compliant, e\&.g\&. MGE UPS SYSTEMS, Liebert, perhaps others (default)
.PP
\fBmge\fR
.RS4
MGE UPS SYSTEMS and MGE Office Protection Systems devices with SNMP cards (ref 66062, 66045, 66074 and 66244)
Set MIB compliance (default=auto, allowed entries: refer to the above SUPPORTED HARDWARE)\&. With "auto", the driver will try a select set of SNMP objects until it finds one that the device responds to\&. Note that, since NUT 2\&.6\&.2, snmp\-ups has a new method that uses sysObjectID, which is a pointer to the prefered MIB of the device, to detect supported devices\&. This renders void the use of
Set polling frequency in seconds, to reduce network flow (default=30)
.RE
.PP
\fBnotransferoids\fR
.RS4
Disable the monitoring of the low and high voltage transfer OIDs in the hardware\&. This will remove input\&.transfer\&.low and input\&.transfer\&.high from the list of variables\&. This should only be used on APCC Symmetra equipment which has strangeness in the three\-phase power reporting\&.
.RE
.PP
\fBsecLevel\fR=\fIvalue\fR
.RS4
Set the securityLevel used for SNMPv3 messages (default=noAuthNoPriv, allowed: authNoPriv,authPriv)
.RE
.PP
\fBsecName\fR=\fIvalue\fR
.RS4
Set the securityName used for authenticated SNMPv3 messages (no default)
.RE
.PP
\fBauthPassword\fR=\fIvalue\fR
.RS4
Set the authentication pass phrase used for authenticated SNMPv3 messages (no default)
.RE
.PP
\fBprivPassword\fR=\fIvalue\fR
.RS4
Set the privacy pass phrase used for encrypted SNMPv3 messages (no default)
.RE
.PP
\fBauthProtocol\fR=\fIvalue\fR
.RS4
Set the authentication protocol (MD5 or SHA) used for authenticated SNMPv3 messages (default=MD5)
.RE
.PP
\fBprivProtocol\fR=\fIvalue\fR
.RS4
Set the privacy protocol (DES or AES) used for encrypted SNMPv3 messages (default=DES)

.SH"REQUIREMENTS"
.sp
You will need to install the Net\-SNMP package from http://www\&.net\-snmp\&.org/ before building this driver\&.
.sp
SNMP v3 also requires OpenSSL support from http://www\&.openssl\&.org\&.
.SH"LIMITATION"
.SS"Shutdown"
.sp
This driver does not provide a proper upsdrv_shutdown() function\&. There probably never will be one, since at the time this script should run (near the end of the system halt script), there will be no network capabilities anymore\&. Probably the only way to shutdown an SNMP UPS is by sending it a shutdown with delay command through \fBupscmd\fR(8) and hope for the best that the system will have finished shutting down before the power is cut\&.
.SH"INSTALLATION"
.sp
This driver is only built if the Net\-SNMP development files are present on the system\&. You can also force it to be built by using "configure \-\-with\-snmp=yes" before calling make\&.
.SH"IMPLEMENTATION"
.sp
The hostname of the UPS is specified with the "port" value in ups\&.conf, i\&.e\&.:
