Bandwidth Utilization
Utilization is the percentage of a network's bandwidth that is currently being consumed by network traffic. Each vertical bar represents the highest utilization on a port, and can be either transmitted (Tx) traffic or received (Rx) traffic during the last time interval in seconds.
Use this screen to view the Switch’s bandwidth utilization settings. Click Monitor > Port > Port > Bandwidth Utilization.
Each field is described in the following table.

PoE Settings
The Switch supports both the IEEE 802.3af Power over Ethernet (PoE) and IEEE 802.3at High Power over Ethernet (PoE) standards. The Switch is Power Sourcing Equipment (PSE) because it provides a source of power through its Ethernet ports, and each device that receives power through an Ethernet port is a Powered Device (PD).
The PoE function and the following screens are available for models ending in “HP” and “EP” only.Make sure your PoE Switch is using the latest firmware.You can also set priorities so that the Switch is able to reserve and allocate power to certain PDs.
The PoE devices that supply or receive power and their connected Ethernet cables must all be completely indoors.PoE Standards and PoE Features
PoE standards vary primarily based on the power budget they provide. PoE standards are:
• IEEE 802.3af Power over Ethernet (PoE)
• IEEE 802.3at Power over Ethernet (PoE+)
The following table describes the differences among the PoE standards.
PoE FEATURES | PoE | PoE+ |
|---|---|---|
IEEE Standard | IEEE 802.3af | IEEE 802.3at |
PoE Type | Type 1 | Type 2 |
Switch Port Power | ||
IEEE Power Classification | Class 0, 1, 2, 3 | Class 4 |
Maximum Power Per Port | 15.4 W | 30 W |
Port Voltage Range | 44 - 57 V | 50 - 57 V |
Cables | ||
Twisted Pairs Used | 2-pair | 2-pair |
Supported Cables | Cat3 or better | Cat5 or better |
To view the current amount of power that PDs are receiving from the Switch, click Monitor > Port > PoE.
Each field is described in the following table.
Label | Description |
|---|---|
PoE Mode | This field displays the power management mode used by the Switch, whether it is in Classification or Consumption mode. |
Total Power(W) | This field displays the total power the Switch can provide to the connected PoE-enabled devices on the PoE ports. |
Consuming Power(W) | This field displays the total amount of power the Switch is currently supplying to the connected PoE-enabled devices. |
Allocated Power(W) | This field displays the total amount of power the Switch (in Classification mode) has reserved for PoE after negotiating with the connected PoE devices. It shows NA when the Switch is in Consumption mode. Consuming Power (W) can be less than or equal but not more than the Allocated Power (W). |
Remaining Power(W) | This field displays the amount of power the Switch can still provide for PoE. Note: The Switch must have at least 16 W of remaining power in order to supply power to a PoE device, even if the PoE device needs less than 16 W. |
Bandwidth Management
This section shows you the maximum bandwidth using the Bandwidth Management screen. Bandwidth management shows the maximum allowable bandwidth for incoming and/or out-going traffic flows on a port.
Bandwidth Control
Use this screen to view the Switch’s bandwidth control in egress global burst and port rate.
An egress port is an outgoing port, that is, a port through which a data packet leaves for both ports. An ingress port is an incoming port, that is, a port through which a data packet enters.
Click Monitor > Port > Bandwidth Management > Bandwidth Control.
Each field is described in the following table.
Label | Description |
|---|---|
Bandwidth Control | |
Egress Global Burst | This field specifies the current egress burst size in bytes all ports. |
Port Rate | View the maximum bandwidth allowed in kilobits per second (Kbps) for the traffic flow on a port. |
Port | This field displays the port number. |
Ingress RateLimit (Kbps) | View the maximum bandwidth allowed in kilobits per second (Kbps) for the incoming traffic flow on a port. |
Egress RateLimit (Kbps) | View the maximum bandwidth allowed in kilobits per second (Kbps) for the out-going traffic flow on a port. |
Storm Control
This section shows you the storm control feature.
Storm control limits the number of broadcast, multicast and unicast packets the Switch receives per second on the ports. When the maximum number of allowable broadcast, multicast and/or unicast packets is reached per second, the subsequent packets are discarded. Enabling this feature reduces broadcast, multicast and/or unicast packets in your network. You can specify limits for each packet type on each port.
Click Monitor > Port > Storm Control.
Each field is described in the following table.
Label | Description |
|---|---|
Storm Control | |
Port | This field displays the port number. |
State | This field displays the state. |
Broadcast (pps) | Displays how many broadcast packets the port receives (in pps). |
Unknown Multicast (pps) | Displays how many unknown multicast packets the port receives (in pps). |
Unknown Unicast (pps) | Displays how many unknown unicast packets the port receives (in pps). |
Action | Displays the action the device takes when a limit is reached. The following options are available: • Drop – drop the packet. • Shutdown – shutdown the connection. |
