Usage guidelines

With AI-driven PoE enabled, the device automatically recovers a PI when it fails. If more than one PI fails simultaneously, the device recovers the PIs one by one in ascending order of PI number.

AI-driven PoE automatically adjusts the power supply parameters to fit the power needs. If you disable AI-driven PoE, the system reverts the parameters to the settings before the adjustment.

AI-driven PoE takes effect only on PSEs that run firmware V147 or later.

· Firmware earlier than V147—You must use the poe update command to upgrade the PSE firmware and then enable AI-driven PoE on the PSE.

· Firmware V147 or later—You do not need to re-enable AI-driven PoE after upgrading the firmware if you have enabled the feature before the upgrade.

Examples

# Enable AI-driven PoE.

poe class-detect ignore

Use poe class-detect ignore to ignore the PD power class.

Use undo poe class-detect to restore the default.

NOTE:

This command is supported only in Release R6352P01 and later.

Syntax

poe class-detect ignore

undo poe class-detect

Default

The device supplies power to a PD based on the detected power class of the PD.

Views

PI view

Predefined user roles

network-admin

Usage guidelines

By default, before supplying power to a PD, the device detects the power class of the PD and supplies power to the PD based on the detected power class. For example, if the device detects the power class of 1 for a PD, the device can provide a maximum power of 12.95 W to the PD. If the power required by a PD is greater than 12.95 W, the device will stop supplying power to the PD.

After configuring this command, the device will continue to detect the PD power class before supplying power to a PD, but it will not limit the power supplied to the PD based on the detected power class. As long as the power required by the PD does not exceed the maximum allowed power on the interface (configured by using the poe max power command in interface view), the device can supply power to the PD.

If you execute the poe class-detect ignore command multiple times, and the most recent configuration will take effect.

Examples

# Configure GigabitEthernet 1/0/1 to ignore the PD power class.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

Versions

Default setting

Versions earlier than Release 6350

The PD detection mode is strict.

Release 6350 and later

· If the device starts up with the initial configuration, the PD detection mode is strict.

· If the device starts up with the factory defaults, the PD detection mode is simple.

Parameters

none: Enables the device to supply power to PDs that are correctly connected to the device without causing short circuit.

simple: Enables the device to supply power to PDs that comply with basic requirements of 802.3af or 802.3at.

strict: Enables the device to supply power to PDs that comply with all requirements of 802.3af or 802.3at.

Usage guidelines

CAUTION:

A non-PD device might be damaged when power is supplied to it. To avoid device damage, do not specify the none keyword when the PI connects to a non-PD device.

This command is available only for a PSE that has a model name ending with a character of B, LSPPSE48B for example. To obtain the model name of a PSE, execute the display poe pse command.

To configure the detection mode for nonstandard PDs, first execute the poe legacy enable command to enable detection for nonstandard PDs.

Usage guidelines

CAUTION:

This command enables the device to supply power to a PD directly without performing a detection of the PD. To avoid damaging the PD, make sure the power provided by the device meets the PD specifications before executing this command.

Before supplying power to a PD, the device performs a detection of the PD. It supplies power to the PD only after the PD passes the detection. If the PD fails the detection but the power provided by the device meets the PD specifications, you can execute this command to enable forced power supply to the PD.

Examples

# Enable forced PoE power supply.

poe guard-band

Use poe guard-band to set the PoE guard band.

Use undo poe guard-band to restore the default.

NOTE:

This command is supported only in R6352P01 and later.

Syntax

poe pse pse-id guard-band power

undo poe pse pse-id guard-band power

Default

By default, the PoE guard band is 30 W.

Views

System view

Predefined user roles

network-admin

Parameters

pse-id: Specifies a PSE by its ID.

power: Specifies the PoE guard band in the range of 0 to 30, in watts.

Usage guidelines

Application scenarios

PoE guard band is a specified amount of power reserved to prevent PSE power overload in case of PD power jitter. For example, if the maximum power of the PSE is 200 W and the guard band is 30 W, the PSE can provide a maximum power of 170 W to all PDs. If the total power of PDs reaches 170 W, no power will be supplied to new PDs.

When the PD operates stably with low power jitter (less than the default guard band), you can use the poe pse guard-band command to decrease the guard band and use the released PSE power to power the new PDs.

Restrictions and guidelines

Before executing this command, execute the display poe interface command to check the value of the Remaining field. If the guard band is greater than the value of Remaining field, some PDs being powered might have a power down. For example, if the network administrator changes the guard band from 10 W to 30 W when the remaining power is 10 W, some PDs that are currently being powered might have a power down to make up for the 20 W power gap.

Examples

# Set the PoE guard band to 30 W.

Parameters

pse pse-id: Specifies a PSE by its ID.

Usage guidelines

CAUTION:

Inrush currents might damage the components on the device. Use this command with caution.

This command is available only for a PSE that has a model name ending with a character of B, LSPPSE48B for example. To obtain the model name of a PSE, execute the display poe pse command.

Inrush current might occur at PD startup and trigger PSE self-protection, As a result, the PSE stops supplying power to the PDs. To continue power supply to the PDs, configure this feature to allow inrush currents drawn by PDs.

IEEE 802.3af and IEEE 802.3at define specifications for inrush current. Support for the specifications defined by IEEE 802.3af and/or IEEE 802.3at depends on the device model.

poe mps

Use poe mps to set the TMPDO for Maintain Power Signature (MPS).

Use undo poe mps to restore the default.

NOTE:

This command is supported only in Release R6350 and later.

Syntax

poe mps pse pse-id tmpdo { timer | long |normal }

undo poe mps pse pse-id tmpdo

Default

The normal TMPDO mode is used for the MPS. The TMPDO is 324 milliseconds.

Views

System view

Predefined user roles

network-admin

Parameters

pse-id: Specifies a PSE by its ID.

timer: Sets the TMPDO for the MPS. The value is a multiple of 4 in the range of 300 to 400, in milliseconds.

long: Specify the long TMPDO mode. The TMPDO is 360 milliseconds.

normal: Specifies the normal TMPDO mode. The TMPDO is 324 milliseconds.

Usage guidelines

The MPS is an electronic signature provided by a PD. The PD can use this signature to maintain connection to the PSE in sleep mode. The PD sends a PoE protocol-compliant pulse current to the PSE periodically. If the PSE detects the PoE protocol-compliant pulse current from the PD within the TMPDO, it supplies power to the PD. If the PSE does not detect the PoE protocol-compliant pulse current from the PD within the TMPDO, it will not supply power to the PD.

To send pulse currents at larger intervals for lower standby power, you can use this command to change the TMPDO to be longer.

Only PSE modules that have a model name of LSPPSE**A support this feature. To view the PSE models, execute the display poe pse command.

If you execute the command multiple times, the most recent configuration takes effect.

Examples

# Set the TMPDO for the MPS to 350 milliseconds.

Parameters

time: Specifies the delay timer in the range of 1 to 3600, in seconds.

Usage guidelines

By default, the device executes the poe enable command and supplies power to an interface immediately when any one of the following conditions is met:

· The poe enable command is configured.

· The device reboots with the poe enable command in the configuration file.

· The interface comes up and the PoE module resumes PoE power supply to the interface.

After the poe power-delay command is configured, the system creates a PoE delay timer after the poe enable command is configured and allows the PoE module to supply power to the PI only after the timer expires.

The undo poe enable command is executed immediately upon configuration and is not affected by the poe power-delay command.

Examples

# Enable PoE delay and set the delay timer to 30 seconds.

<Sysname> system-view

[Sysname] poe power-delay 30

Predefined user roles

network-admin

Parameters

critical: Sets the power supply priority to critical. The PI with critical power priority operates in guaranteed mode. Power is first supplied to the PD connected to the critical PI.

high: Sets the power supply priority to high.

low: Sets the power supply priority to low.

Usage guidelines

When the PoE power is insufficient, power is first supplied to PIs with higher priority.

For PIs with same power supply priority, the PI with the smallest ID is allocated with power first.

If a PoE profile has been applied to a PI, remove the application before configuring the PI in PoE profile view.

If a PI has been configured, remove the configuration before configuring the PI in PI view.

Usage guidelines

During the system warm reboot process (upon execution of the reboot command), the PIs continue supplying power to the PDs but data connections between the PDs and the device are interrupted. After the system reboots, PDs might not re-initiate data connections with the device. Power cycling PIs upon a system warm reboot allows the PDs to re-establish data connections with the device.

Examples

# Enable PI power cycling upon a system warm reboot.

Default

By default, the PoE standard of a PI is IEEE 802.3bt.

Views

PI view

Predefined user roles

network-admin

Parameters

at: Specify the IEEE 802.3at standard.

bt: Specify the IEEE 802.3bt standard.

Usage guidelines

For this command to take effect, restore the maximum power of the PI to the default before executing the command.

IEEE released 802.3af (PoE), 802.3at (PoE+), and 802.3bt (PoE++) standards in chronological sequence. These standards are backward compatible but forwards incompatible. Before supplying power to a PD, a PI will detect the PD, determine the power class for the PD based on its power requirement, and supplies power to the PD based on the power class.

· 802.3af—Defines four power classes 0 to 3 and provides a maximum power of 12.95 W.

· 802.3at—Adds class 4 in addition to the four power classes defined by 802.3af and provides a maximum power of 25.5 W.

· 802.3bt—Adds classes 5 to 8 in addition to the five power classes defined by 802.3at and provides a maximum power of 71 W.

Specify a PoE standard based on the power requirement of the PD. If the maximum power allowed by the standard is less than that required by the PD, the PI will not supply power to the PD.

CAUTION:

When a PI is operating in 802.3bt mode and providing a power output over 30 W, changing the PoE standard might cause a power cycle of the PD. Before changing the PoE standard, make sure you understand its impact on the live network.

Views

System view

Predefined user roles

network-admin

Usage guidelines

By default, the device continues supplying power to an interface after the interface is shut down by the shutdown command or by an upper layer module such as monitor link. As a result, the PD connected to the shutdown interface operates continuously but fails to access the network.

This command disables the PoE module from supplying power to an interface after the interface is shut down. After the interface comes up, the PoE module resumes power supply to the interface.

The command does not power off an interface that has been shut down but is supplying power to a PD.
