PoE Information
The PoE overlay displays the power supply and consumption status of the elements in the 
network.
This overlay applies colors to links based on the amount of power provided by the link to 
power supplying devices based on their remaining power. The overlay also highlights devices 
requesting power that are not receiving the power requested. The user can select the thresholds 
where these colors change for each type of data, and the specific colors used for each threshold 
reached.
An icon is added to power-supplying switches, and is colored according to the switches power 
budget consumption.
• Device supplying 0-80% of its power budget — Normal
• Device supplying 81-95% of its power budget — Yellow
• Device supplying 96-100% of its power budget — Red
Devices receiving power over Ethernet are surrounded by a halo.
Connections containing at least one link over which power is supplied are highlighted in the 
topology map.
In the connection explorer, each link transferring power displays an indication of providing 
power, and the direction of the power flow. This indication is displayed per port, even if the 
link is in a LAG. It is possible that some links in a LAG provide power while others do not.
VLAN Membership
This overlay enables viewing of the VLAN memberships of various ports and devices in the 
network.
