Configuring PoE Settings on AOS-S Ports
Power over Ethernet Ethernet is a network protocol for data transmission over LAN. (PoE Power over Ethernet. PoE is a technology for wired Ethernet LANs to carry electric power required for the device in the data cables. The IEEE 802.3af PoE standard provides up to 15.4 W of power on each port.) is a technology that allows the switches to deliver power to the powered devices (PD). If you have switches provisioned in UI groups, you can enable or disable PoE operation on switch ports. The PoE page displays the configuration details of all PoE enabled ports.
To configure the PoE settings of a switch, complete the following steps:
- In the WebUI, select one of the following options:
- To select a switch group in the filter:
- Set the filter to a group containing at least one switch.
The dashboard context for the group is displayed.
- Under , click > .
- Click the AOS-S or icon to view the switch configuration dashboard.
- Set the filter to a group containing at least one switch.
- To select a switch in the filter:
- Set the filter to or a group containing at least one switch.
- Under , click > .
A list of switches is displayed in the view.
- Click a switch under .
The dashboard context for the switch is displayed.
- Under , click .
The tabs to configure the switch is displayed.
- To select a switch group in the filter:
- Click > . The page is displayed.
- Select the port(s) you want to edit and click .
The window is displayed. - Configure the following parameters:
Table 1: PoE Parameters
Name
Description
Value The number assigned to the switch port. The port number is auto-generated and cannot be changed in the settings.
Auto-generated port number
The status of the PoE operation on the port. When PoE is enabled, the switch sends power to the powered device (PD).
Enabled or Disabled
The PoE priority level of the port. If there is not enough power available to provision all active PoE ports, then PoE ports at priority level as critical are powered first, then high and low priority at the last.
Low, High or Critical
The status of the LLDP Link Layer Discovery Protocol. LLDP is a vendor-neutral link layer protocol in the Internet Protocol suite used by network devices for advertising their identity, capabilities, and neighbors on an IEEE 802 local area network, which is principally a wired Ethernet. MED TLV Type-length-value or Tag-Length-Value. TLV is an encoding format. It refers to the type of data being processed, the length of the value, and the value for the type of data being processed. configuration. Switches use LLDP to repeatedly query the PD to discover the power requirement and send the exact power required.
Enabled or Disabled
The status of the LLDP Dot3 TLV configuration.
Enabled or Disabled
The PoE power allocation method used for the port. If usage is selected, then the allocation is made based on the automatic allocation by the PD. If class is selected, then the allocation is made based on class of the PD.
Usage or Class
The status of support for pre-standard devices. When this option is enabled, switch supports some pre-802.3af 802.3af is an IEEE standard for Power over Ethernet (PoE) version that supplies up to 15.4W of DC power. See PoE. devices.
Enabled or Disabled
The user-defined identifier for the port to identify its intended use.
A string
The status of LLDP in PoE page is displayed as Enabled only if one or both LLDP settings (LLDP MED TLV (PoE) and LLDP Dot3 TLV (PoE+ Power over Ethernet+. PoE+ is an IEEE 802.3at standard that provides 25.5W power on each port.)) are enabled for the port.
