"""Uses the Cisco proprietary CISCO-POWER-ETHERNET-EXT-MIB to map the group/port
index pairs used exclusively in PORT-ETHERNET-MIB to an actual ifIndex, that
most other MIBs (and NAV's Interface model) uses for identification of
interfaces/ports.
POWER-ETHERNET-MIB provides only a very vague identification of power-enabled
ports. These identifiers are not universally and consistently mappable to an
ifIndex, for example. A more conclusive mapping to interfaces may be provided
on a vendor-by-vendor basis. The only supported vendor for mapping in this
codebase so far is Cisco.
Cisco's mapping is indirect via the ENTITY-MIB - each entry from the power
ethernet tables is mapped to a physical port in ENTITY-MIB::entPhysicalTable
via its entPhysicalIndex. This table, in turn, can map physical ports to
interface indexes from the IF-MIB::ifTable.
