enable inline-power

enable inline-power [{fast {ports [port_list | all]}} | perpetual]

Description

Enables This command is available on the ExtremeSwitching X440-G2, X450-G2, X460-G2, X620, and X465 series switches., and perpetual PoE to all ports; or fast PoE to all ports, or selected ports, for some platforms.

Syntax Description

fast Deliver PoE power to devices at the time of switch power on without waiting for boot up based on last saved PoE state. The default is disabled.
ports For fast PoE, specifies selecting ports. ExtremeSwitchingX465 series switch only.
port_list For fast PoE, specifies the port list separated by a comma or -. ExtremeSwitching X465 series switch only.
all For fast PoE, specifies selecting all ports. ExtremeSwitching X465 series switch only.
perpetual Preserves PoE power delivery to devices during reboot. Perpetual PoE is a switch-wide setting. The default is disabled.

Default

By default:
  • PoE is enabled.
  • Fast PoE is disabled.
  • Perpetual PoE is disabled.

Usage Guidelines

You can control whether inline power is provided to the system by using the disable inline-power command and the enable inline-power command. By default, inline power provided to all ports is enabled. Additionally, you can opt to deliver PoE power to devices at the time of switch power on without waiting for boot up (fast PoE) based on last saved PoE state. Per-port fast PoE is available on certain platforms. You can also elect to preserve PoE power delivery to devices during reboot (perpetual PoE). The default for both PoE options is disabled.

Enabling inline power starts the PoE detection process used to discover, classify, and power remote PDs.

Disabling inline power using the disable inline-power command does not affect the data traffic traversing the port. And, disabling the port using the disable port command does not affect the inline power supplied to the port.

Note

Note

Inline power cannot be delivered to connected PDs unless the switch is powered on.

Example

The following command enables inline power currently provided to all ports:

# enable inline-power
The following example turns on perpetual PoE for the switch:
# enable inline-power perpetual

The following example turns on fast PoE for ports 1,2, and 5:

# enable inline-power fast ports 1,2,5

History

This command was first available in ExtremeXOS 11.1.

The fast and perpetual PoE options were added in ExtremeXOS 30.3.

Per-port fast PoE was added for ExtremeXOS 31.1.

Platform Availability

This command is available on the PoE devices listed in Extreme Networks PoE Devices.

The fast and perpetual options are only available on the ExtremeSwitching X435; X465 (per port) series switches.
