Enables PoE, and perpetual PoE to all ports; or fast PoE to all ports, or selected ports, for some platforms.
| 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. ExtremeSwitching5520 and 5720 series switches only. |
| port_list | For fast PoE, specifies the port list separated by a comma or -. ExtremeSwitching 5520 and 5720 series switches only. |
| all | For fast PoE, specifies selecting all ports. ExtremeSwitching 5520 and 5720 series switches only. |
| perpetual | Preserves PoE power delivery to devices during reboot. Perpetual PoE is a switch-wide setting. The default is disabled. |
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
Inline power cannot be delivered to connected PDs unless the switch is powered on.The following command enables inline power currently provided to all ports:
# enable inline-power
# 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
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.
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 5520 and 5720 (per port) series switches.
