Command Purpose

Use this command to enable or disable the global Poe function.

Prerequisites

Command Syntax

poe global (enable | disable)

Command Mode

Global Config

Default

Enable

Usage

The Poe configuration of the ports will only take effect when enabled in global mode.

Examples

Disable the global Poe function:

Switch# configure terminal 
Switch(config)# poe global disable
Switch(config)# 

Related Commands

None

Command Purpose

Use this command to select the power distribution policy for the switch.

Prerequisites

Command Syntax

poe power-management policy ( dynamic | static )

Command Mode

Global Config

Default

dynamic

Usage

Adopting dynamic policy can make more use of power supply and provide power to as many ports as possible, but power fluctuations in some port loads may cause unstable power supply to other low-priority ports. Static policy can reserve sufficient power for ports, but it may waste a portion of available power.Static policy is to pre allocate power based on the negotiation type or user configuration value of each port. The supported negotiation types are:

Examples

Set PSE power-management policy is static:

Switch# configure terminal
Switch(config)# poe power-management policy static 
Switch(config)# exit
Switch#  

Related Commands

None

Command Purpose

Use this command to set the reserved-power of poe from available power, When available power is less than it, switch will no longer supply power to the newly connected PD.

Prerequisites

Command Syntax

poe power-reserved POWER-VALUE

Command Mode

Global Config

Default

30000(mW)

Usage

Setting the reserved power too low will affect the reliability of the switch; Setting the reserved power too high will reduce the distributable power and the power supply ability.

Examples

Set PoE reserved-power 45W:

Switch# configure terminal
Switch(config)# poe power-reserved 45000
Switch(config)# exit
Switch#

Related Commands

None

Command Purpose

Use this command to Set the alarm percentage threshold of real-time consumption of power.When the real-time power consumption exceeds or falls below it for the first time, the user will be reminded by the LED on the panel.

Prerequisites

Command Syntax

poe power-threshold PERCENTAGE-VALUE

Command Mode

Global Config

Default

90(%)。

Usage

None

Examples

Set the alarm percentage threshold is 85%:

Switch# configure terminal
Switch(config)# poe power-threshold 85
Switch(config)# exit
Switch#

Related Commands

None

Command Purpose

Use this command to enable or disable poe function on this port,and attach time-range to enable or disable the PoE function according to the schedule.When the global poe mode is enabled, this command takes effect.

Prerequisites

Command Syntax

poe enable

poe disable

poe enable time-range TIME-RANGE

no poe enable disable time-range TIME-RANGE

poe disable time-range TIME-RANGE

no poe enable disable time-range TIME-RANGE

Command Mode

Interface Configuration

Default

enable

Usage

Use the no of this command only to remove the bound “time range”,and PoE status of the port is determined by the “Poe enable/disable” command.

Examples

Configure the eth-0-1 to supply power only during working hours:

Switch# configure terminal 
Switch(config)# time-range worktime
Switch(config-tm-range)# periodic 9:00 weekdays to 18:00
Switch(config-tm-range)# exit
Switch(config)# inter eth-0-1
Switch(config-if)# poe disable 
Switch(config-if)# poe enable time-range worktime
Switch(config-if)#

Related Commands

poe global enable|disable

Command Purpose

Use this command to set the power supply priority of port.Use the no of this command to return the port to its default value.With the same priority, the port with smaller port-number will be powered first.

Prerequisites

Command Syntax

poe priority (low | high | critical )

no poe priority

Command Mode

Interface Configuration

Default

Low

Usage

None

Examples

Set poe priority of ports eth-0-1 - 4 is high,and ports eth-0-5 - 8 is critical:

Switch# configure terminal 
Switch(config)# interface range eth-0-1 - 4
Switch(config-if-range)# poe priority high 
Switch(config-if-range)# interface range eth-0-5 - 8
Switch(config-if-range)# poe priority critical 
Switch(config-if-range)# end
Switch#

no poe max-power

Command Mode

Interface Configuration

Default

Switch(config)# interface eth-0-1
Switch(config-if)# poe max-power 60000 
Switch(config-if)# end
Switch#

Prerequisites

Command Syntax

poe legacy

no poe legacy

Command Mode

Interface Configuration

Default

Not compatible with legacy PD

Usage

None

Examples

Enable the eth-0-24 compatibility with legacy PD，detect and supply power to non-standard PD:

Switch(config)# interface eth-0-24
Switch(config-if-range)# poe legacy  
Switch(config-if-range)# end
Switch# 

Related Commands

None

Command Purpose

Use this command to force the port to supply power to the PD. The no of this command is used to turn it off.

After configuring this function, the device will skip the check and directly supply power to the PD. Users need to ensure that the electrical energy provided by the device matches the electrical parameters required by the PD. Otherwise, it may cause damage to the PD. Please be careful to enable this function.

Prerequisites

Command Syntax

poe forced-power

no poe forced-power

Command Mode

Interface Configuration

Default

No force port PoE

Usage

After configuring this function, the device will skip the check and directly supply power to the PD. Users need to ensure that the electrical energy provided by the device matches the electrical parameters required by the PD. Otherwise, it may cause damage to the PD.
