# OK, sorry for this insane code - the pysnmp docs explicitly say you
# should just copy paste their examples.
# This is based on the code from here:
# http://snmplabs.com/pysnmp/examples/hlapi/asyncore/sync/manager/cmdgen/modifying-variables.html
# The command we would run to power on outlet 1 on the PDU, if we were
# not masochists is this:
#
# snmpset -v 1 -c private $IPADDR CPS-MIB::ePDUOutletControlOutletCommand.1 i immediateOn
#
# However to get those human-readable names to work we'd need to
# download MIBs and tell pysnmp about them. pysnmp + pysmi apparently
# know how to do this but I tried to point it at the CyberPower MIB file
# and it failed silently so huffed and gave up.
#
# So instead, we're going to do something more akin to this command,
# which is exactly the same thing but without the human-readable names:
#
# snmpset -v 1 -c private $IPADDR .1.3.6.1.4.1.3808.1.1.3.3.3.1.1.4.2 i 1
#
# In that command ".1.3.6.1.4.1.3808.1.1.3.3.3.1.1.4.2" is the
# masochistic name for "CPS-MIB::ePDUOutletControlOutletCommand.2" and
# "1" is the masochistic name for "immediateOn"
#
# I figured out what that command would be by running this:
# snmptranslate -On CPS-MIB::ePDUOutletControlOutletCommand
#
# SnmpEngine and ContextData are just pointless boilerplate required by
# pysnmp. Hopefully you can sort of see how the other bits map to the
# code below (the "i" becaomse "Integer32").
