NAME

snmp-ups - Multi-MIB Driver for SNMP UPS equipment

SYNOPSIS

snmp-ups -h

snmp-ups -a UPS_NAME [OPTIONS]

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, such as:

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
eaton_pw_nm2: Powerware devices with ConnectUPS SNMP cards, as well as UPSes with Eaton Gigabit Network Cards (Network-M2) (renamed from pw)
eaton_pxg_ups: Eaton devices with Power Xpert Gateway UPS Card (renamed from pxgx_ups)
aphel_genesisII: Eaton Powerware ePDU Monitored
aphel_revelation: Eaton Powerware ePDU Managed
raritan: Various Raritan PDUs (Dominion PX, PM, RPC)
raritan-px2: Various Raritan PDUs (Dominion PX2)
baytech: Various BayTech PDUs
cpqpower: HP/Compaq AF401A management card, perhaps others
cyberpower: Cyberpower RMCARD201. Should also support RMCARD100 (net version), RMCARD202 and RMCARD301
huawei: Huawei UPS5000-E, perhaps others
tripplite: TrippLite UPSes; at this time this is the IETF MIB mapping with just the Tripplite entry point OID to verify the device vendor, and a real hardware-specific configuration will be added in the future development.

For a complete and up-to-date listing, you can query the driver by passing the mibs=--list argument (see below).

EXTRA ARGUMENTS

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

port=hostname[:port]: Set SNMP hostname, or IP address, and port number of the peer SNMP agent. There is no default for the hostname, but the default port is 161.
mibs=--list: A special option which allows to list the currently known MIB-to-NUT mappings and exit the driver binary, intended for command-line usage like this:

$ snmp-ups -a snmp-test -x mibs=--list

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 preferred MIB of the device) to detect supported devices. This renders void the requirement to use the "mibs" option.
community=name: Set community name (default = public). Note that a RW community name is required to change UPS settings and send commands (as for a powerdown).
snmp_version=version: Set SNMP version (default = v1, allowed: v2c, v3)
snmp_retries=retries: Specifies the number of Net-SNMP retries to be used in the requests (default=5)
snmp_timeout=timeout: Specifies the Net-SNMP timeout in seconds between retries (default=1)
symmetrathreephase: Enable APCC three phase Symmetra quirks (use on APCC three phase Symmetras): Convert from three phase line-to-line voltage to line-to-neutral voltage (default: not enabled)
pollfreq=num: Set polling interval for full updates, in seconds, to reduce SNMP network traffic relative to the quick updates performed every "pollinterval" (the latter option is described in ups.conf(5)). The default value is 30 (in seconds).
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) This parameter is mandatory if you use non-trivial authentication.
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, SHA, SHA256, SHA384 or SHA512) used for authenticated SNMPv3 messages (default=MD5). Note that the exact protocol list depends on Net-SNMP library capabilities; check help of the snmp-ups binary program for the run-time supported list.
privProtocol=value: Set the privacy protocol (DES, AES, AES192 or AES256) used for encrypted SNMPv3 messages (default=DES). Note that the exact protocol list depends on Net-SNMP library capabilities; check help of the snmp-ups binary program for the run-time supported list.

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, and may include a non-standard (161) remote peer port:

        [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 = 166.99.224.132:170
                snmp_version = v3
                secLevel = authPriv
                secName = mysecurityname
                authPassword = myauthenticationpassphrase
                privPassword = myprivatepassphrase
                desc = "Example SNMP v3 device, with the highest security level"
