NOTE

This man page only documents the hardware-specific features of the snmp-ups driver. For information about the core driver, see nutupsdrv(8).

SUPPORTED HARDWARE

The snmp-ups driver automatically detects and supports a wide range of devices by loading various MIBS:

ietf

UPS that is RFC 1628 (UPS MIB) compliant, e.g. MGE UPS SYSTEMS, Liebert, perhaps others (default)

mge

MGE UPS SYSTEMS and MGE Office Protection Systems devices with SNMP cards (ref 66062, 66045, 66074 and 66244)

apcc

APC AP9605, AP9606, AP9617, and AP9618 APC network management cards, as well as any others supporting the APC POWERNET MIB

netvision

Socomec Sicon UPS with Netvision Web/SNMP management card/external box

pw

Powerware devices with ConnectUPS SNMP cards

aphel_genesisII

Eaton Powerware ePDU Monitored

aphel_revelation

Eaton Powerware ePDU Managed

raritan

Various Raritan PDUs

baytech

Various BayTech PDUs

cpqpower

HP/Compaq AF401A management card, perhaps others

cyberpower

Cyberpower RMCARD201. Should also support RMCARD100 (net version), RMCARD202 and RMCARD301

EXTRA ARGUMENTS

This driver supports the following optional settings in the ups.conf(5):

mibs=name

Set MIB compliance (default=auto, allowed entries: refer to SUPPORTED HARDWARE above). 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 "mibs" option.

community=name

Set community name (default = public). Note that a RW community name is required to change UPS settings (as for a powerdown).

snmp_version=version

Set SNMP version (default = v1, allowed: v2c, v3)

pollfreq=value

Set polling frequency in seconds, to reduce network flow (default=30)

notransferoids

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.

secLevel=value

Set the securityLevel used for SNMPv3 messages (default=noAuthNoPriv, allowed: authNoPriv,authPriv)

secName=value

Set the securityName used for authenticated SNMPv3 messages (no default)

authPassword=value

Set the authentication pass phrase used for authenticated SNMPv3 messages (no default)

privPassword=value

Set the privacy pass phrase used for encrypted SNMPv3 messages (no default)

authProtocol=value

Set the authentication protocol (MD5 or SHA) used for authenticated SNMPv3 messages (default=MD5)

privProtocol=value

Set the privacy protocol (DES or AES) used for encrypted SNMPv3 messages (default=DES)

REQUIREMENTS

You will need to install the Net-SNMP package from http://www.net-snmp.org/ before building this driver.

SNMP v3 also requires OpenSSL support from http://www.openssl.org.

LIMITATIONS

Shutdown

The shutdown sequence should be tested before relying on NUT to send a shutdown command to the UPS. The problem is that the host network stack may have been torn down by the time the driver is invoked to send the shutdown command. The driver attempts to send shutdown.return, shutdown.reboot, and load.off.delay commands to the UPS in sequence, stopping after the first supported command.

INSTALLATION

This driver is only built if the Net-SNMP development files are present at configuration time. You can also force it to be built by using configure --with-snmp=yes before calling make.

EXAMPLES

The hostname of the UPS is specified with the "port" value in ups.conf:

[snmpv1]
        driver = snmp-ups
        port = snmp-ups.example.com
        community = public
        snmp_version = v1
        pollfreq = 15
        desc = "Example SNMP v1 device"
[snmpv3]
        driver = snmp-ups
        port = 166.99.224.132
        snmp_version = v3
        secLevel = authPriv
        secName = mysecurityname
        authPassword = myauthenticationpassphrase
        privPassword = myprivatepassphrase
        desc = "Example SNMP v3 device, with the highest security level"
