Delivering Power [W]: Displays which port supplies the PD Power and shows the power consumed by the port.
Current (mA): The current supplied to the PD by the port.
PD Class: The Class of the PD linked to the switch’s port.
Priority: Choose from three options: Normal, Low, and High. Default is Normal. The switch will stop supplying the power to the port
based on the order of the priority Low
Normal
High in case total power required by all PDs linked to the switch exceeds the power
limit. IFf the ports have the same priority, then the switch will stop supplementing power from the port with the highest port id (8
1).
Allocation (W): The power consumed by the port.
4.7 GVRP
GVRP is an application based on Generic Attribute Registration Protocol (GARP), mainly used to automatically and dynamically maintain
the group membership information
of the VLANs. The GVRP provides the VLAN registration service through a GARP application. It uses
GARP Information Declaration (GID) to maintain the ports associated with their attribute database and GARP Information Propagation
(GIP) to communicate among switches and end stations. With GID information and GIP, GVRP state machines maintain the contents of
Dynamic VLAN Registration Entries for each VLAN and propagate this information to other GVRP-aware devices to setup and update
their knowledge database, the set of VLANs associated with currently active members, and through which ports these members can
be reached.
In GVRP Configuration function folder, there are three functions supported: GVRP Config, GVRP Counter, and GVRP.
4.7.1 Config
Function name: GVRP Configuration
Function description: GVRP Config is used to configure each port’s GVRP operation mode. Seven parameters need to be configured as
described below.

Parameter description:
GVRP State: This function lets you enable or disable the GVRP function. From the drop-down list, click on the the <Downward> arrow
key to choose “Enable” or “Disable.” Then, click on the <Apply> button and the system will take effect immediately.
Join Time: Used to declare the Join Time in unit of centisecond. Valid time range: 20–100 centisecond, Default: 20 centisecond.
