Disables the non-standard (or capacitance) power detection mechanism for the switch.
This command has no arguments or variables.
Disable.
This command disables the non-standard power-detection mechanism on the switch. Legacy PDs do not conform to the IEEE 802.3af standard but may be detected by the switch through a capacitance measurement.
However, measuring the power through capacitance is used only if this parameter is enabled and after an unsuccessful attempt to discover the PD using the standard resistance measurement method. The default for legacy is disabled.
The reason legacy detection is configurable is that it is possible for a normal (non-PoE) device to have a capacitance signature that causes the device to be detected as a legacy PoE device and have power delivered to it, potentially causing damage to the device.
The following command disables capacitance detection of PDs on the switch:
disable inline-power legacy
This command was first available in ExtremeXOS 11.5.
This command is available on the Summit family switches listed in Extreme Networks PoE Devices.
