With IPHost Network Monitor you can run simple snmp requests against a Cisco device in your network.
cewEntName
Cisco EnergyWise Ent Name
1.3.6.1.4.1.9.9.683.1.6.1.4
This object specifies an administratively assigned human readable name to the Cisco EnergyWise entity. For example, we can have a switch deployed to lobby with cewEntName as 'LL'. This object specifies a null string if no name is configured. If write access is implemented for an instance of cewEntName, and a value is written into the instance, the agent must retain the supplied value in the cewEntname instance associated with the same physical entity for as long as that entity remains instantiated. This includes instantiations across all re-initializations/reboots of the network management system, including those which result in a change of the physical entity's entPhysicalIndex value.
