Parameters

max-power: Sets the maximum PSE power in watts.The value range is 37 to 87 and 37 to 174 watts for routers installed with a SIC-4FSWP and a DSIC-9FSWP, respectively.

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

Usage guidelines

To avoid the PSE power overload situation, make sure the total power of all PSEs is less than the maximum PoE power.

The maximum power of the PSE must be greater than or equal to the total maximum power of all its critical PIs on the PSE to guarantee these PIs power.

Examples

# Set the maximum PSE power of PSE 4 to 150 watts.

<Sysname> system-view

[Sysname] poe pse 4 max-power 150

poe pd-policy priority

Use poe pd-policy priority to enable PI power management.

Use undo poe pd-policy priority to restore the default.

Syntax

Usage guidelines

If PI power management is disabled, the PSE does not supply power to new PDs when PSE power overload occurs.

If PI power management is enabled, when a PSE is overloaded, the PSE allocates power to PDs based on the priority of their PIs.

Examples

# Enable PI power management.

poe priority

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

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

[Sysname] interface gigabitethernet 1/0/1

[Sysname-GigabitEthernet1/0/1] poe priority critical

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

Use undo poe priority to restore the default.

Syntax

poe priority { critical | high | low } pse pse-id

undo poe priority pse pse-id

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

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.

Usage guidelines

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

poe update

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

Syntax

Single-PSE device:

poe update { full | refresh } filename

Multi-PSE device:

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

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

poe utilization-threshold

Use poe utilization-threshold to configure a power alarm threshold for the PSE.

Use undo poe utilization-threshold to restore the default power alarm threshold of the PSE.

Syntax

poe utilization-threshold value pse pse-id

undo poe utilization-threshold pse pse-id

Default

The power alarm threshold for the PSE is 80%.

Views

System view

Predefined user roles

network-admin

Parameters

value: Specifies alarm threshold as a percentage of 1 to 99.

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

Usage guidelines

If PSE power usage crosses the threshold multiple times in succession, the system sends notification messages only for the first crossing. For more information, see "Configuring SNMP."

Examples

# Set the power alarm threshold of PSE 4 to 90%.

<Sysname> system-view

[Sysname] poe utilization-threshold 90 pse 4

poe-profile

Use poe-profile to create a PoE profile and enter its view, or enter the view of an existing PoE profile.

Use undo poe-profile to delete a PoE profile.

Syntax

poe-profile profile-name [ index ]

undo poe-profile { index index | name profile-name }

Default

No PoE profiles exist.

Views

System view

Predefined user roles

network-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.

<Sysname> system-view

[Sysname] poe-profile abc 3

[Sysname-poe-profile-abc-3]

# Create a PoE profile and name it def. Do not specify the index number.
