Views

System view

Predefined user roles

network-admin

mdc-admin

Parameters

time: Specifies the delay time 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.

The poe power-delay creates a PoE delay timer after the poe enable command is executed 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 time to 30 seconds.

<Sysname> system-view

[Sysname] poe power-delay 30

poe priority (interface view)

Use poe priority to set the power supply priority for a PI.

Use undo poe priority to restore the default.

Syntax

poe priority { critical | high | low }

undo poe priority

Default

The power supply priority of a PI is low.

Views

PI view

PoE profile view

Predefined user roles

network-admin

mdc-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.

Examples

# Set the power supply priority of the PI to critical in PI view.

<Sysname> system-view

Default

The power supply priority of a PSE is low.

Views

System view

Predefined user roles

network-admin

Parameters

critical: Sets the power supply priority to critical. The PSE with critical power priority operates in guaranteed mode, and power is supplied to it first.

high: Sets the power supply priority to high.

low: Sets the power supply priority to low.

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

Usage guidelines

Only the default MDC supports this command.

If PSE power management is disabled, the system does not supply power to new PSEs when PoE power overload occurs.

If PSE power management is enabled, when PSE power overload occurs, the system supplies power to a PSE with higher priority. For multiple PSEs with the same priority, the PSE with a smaller ID gets power supplied first.

For example, if PoE is enabled for a PSE, and the PSE has higher priority, the system performs the following operations:

· Stops supplying power to a PSE with lower priority.

· Supplies power to the PSE that has higher priority.

Examples

# Set the power supply priority of PSE 4 to critical.

Views

System view

Predefined user roles

network-admin

mdc-admin

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.

poe track-shutdown

Use poe track-shutdown to disable PoE on shutdown interfaces.

Use undo poe track-shutdown to restore the default.

Syntax

poe track-shutdown

undo poe track-shutdown

Default

PoE is not disabled on shutdown interfaces.

Views

System view

Predefined user roles

network-admin

mdc-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.

Examples

# Disable PoE on shutdown interfaces.

<Sysname> system-view

[Sysname] poe track-shutdown

Related commands

poe update

Use poe update to upgrade the PSE firmware when the device is operating.

Syntax

poe update { full | refresh } filename pse pse-id

Views

System view

Predefined user roles

network-admin

Parameters

full: Upgrades the PSE firmware in full mode.

refresh: Upgrades the PSE firmware in refresh mode.

filename: Specifies the name of the upgrade file, a case-insensitive string of 1 to 64 characters. The specified file must be in the root directory of the file system of the device.

pse pse-id: Specifies a PSE by its ID. If you do not specify a PSE, all PSEs are upgraded.

Usage guidelines

Only the default MDC supports this command.

You can upgrade the PSE firmware in service in either of the following modes:

· Refresh mode—Updates the PSE firmware without deleting it. You can use the refresh mode in most cases.

· Full mode—Deletes the current PSE firmware and reloads a new one. Use the full mode if the PSE firmware is damaged and you cannot execute any PoE commands.

Examples

# Upgrade the firmware of PSE 4 in service.

<Sysname> system-view

[Sysname] poe update refresh POE-168.bin pse 4

This command will refresh the PSE firmware. Continue? [Y/N]:y

Predefined user roles

network-admin

mdc-admin

Parameters

profile-name: Specifies a PoE profile name, a case-sensitive string of 1 to 15 characters. A PoE configuration file name begins with a letter and must not contain reserved keywords including undo, all, name, interface, user, poe, disable, max-power, mode, priority, or enable.

index: Specifies the index number of a PoE profile, in the range of 1 to 100.

Usage guidelines

To configure PIs in batches, use the PoE profile.

If you do not specify a profile index, the system automatically assigns an index (starting from 1) to the PoE profile.

If a PoE profile is applied, use the undo apply poe-profile command to remove the application before deleting the PoE profile.

Examples

# Create a PoE profile, name it abc, and specify the index number as 3.
