SNMP::Info

When attempting to get infro from a Cisco 3560 or 2960 I get an error like
this:
--
SNMP::Info::_global layers : sysServices.0
SNMP::Info::_global description : sysDescr.0
SNMP::Info::_global id : sysObjectID.0
SNMP::Info::device_type() layers:00000110 id:.1.3.6.1.4.1.9.1.616

The CISCO-POWER-ETHERNET-EXT-MIB did not load. See README for
SNMP::Info::Layer3::C3550

It appears that CiscoPower.em is attempting to call an object that doesn't
exist in CISCO-POWER-ETHERNET-EXT-MIB.my. I'm no SNMP expert, but this
looks the solution (I don't know if it gives the correct results, but it is
my best guess and no longer gives an error):
