Configure PoE Detection Type

Perform the following procedure to configure the PoE powered device (PD) detection type. You can enable either 802.3af and Legacy compliant PD detection methods, or 802.3at and Legacy compliant PD detection methods. The default detection type is 802.3at and legacy.

802.3af : normal power mode
802.3af and legacy
802.3at : high power mode
802.3at and legacy
802.3bt Type 3 : normal power mode
802.3bt Type 4 : normal power mode

802.3at is backwards compatible with 802.3af. Therefore, normal power and high power devices are supported in 802.3at.

Important

Changing from a newer IEEE standard to an older IEEE standard is permitted, however power delivery is interrupted during this operation, and all PoE devices are reset. There is no service interruption when changing from an older IEEE standard to a newer IEEE standard.

Procedure

Enter Global Configuration mode:

enable

configure terminal
Configure PoE detection type:

poe poe-pd-detect-type {802dot3af | 802dot3af_and_legacy | 802dot3at | 802dot3at_and_legacy | 802dot3bt_type3 | 802dot3bt_type4}

Variable Definitions

The following table defines parameters for the poe-pd-detect-type command.


Variable	Value
{802dot3af \| 802dot3af_and_legacy \| 802dot3at \| 802dot3at_and_legacy \| 802dot3bt_type3 \| 802dot3bt_type4}	Configures the detection type to one of the following values: 802dot3af: Set PD detection mode in 802.3af 802dot3af_and_legacy: Set PD detection mode in 802.3af and legacy 802dot3at: Set PD detection mode in 802.3at 802dot3at_and_legacy: Set PD detection mode in 802.3at and legacy 802dot3bt_type3: Set PD detection mode in 802dot3bt Type3 802dot3bt_type4: Set PD detection mode in 802dot3bt Type4
