inline power non-pd-detection enable

Enables detection for nonpowered endpoints or devices (non-PD).
Syntax
inline power non-pd-detection enable
no inline power non-pd-detection enable
Command Default

By default, non-PD detection is enabled.

Modes

Global configuration mode

Usage Guidelines

A multiport PD must be connected to a single unit and must have a LAG defined for the ports.

By default, this feature is enabled and new devices that connect to the Power over Ethernet (PoE) ports are detected.

When this feature is disabled by using the no form of the command, new devices that connect to the PoE ports are not detected.

When this feature is re-enabled after having been disabled, only new devices that connect to the PoE ports are detected. To ensure that all existing non-PDs are detected, you must save the configuration and reload the device or follow the following configuration order.

  1. Configure the LAG for multiport PDs.
  2. Enable non-PD detection mode.
  3. Configure inline power on interfaces.

When the no form of the command is used to disable non-PD detection, the existing non-PD state declarations on the ports are not cleared. The state declarations on the ports clear when they are disconnected from the non-PDs or when you save the configuration and reload the device.

Either reload after disabling the mode or disable and then enable inline power on ports that are in a non-PD state.

When a port has detected a non-PD, it generates the following syslog message:

PoE: Power disabled on port 1/1/21 because of detection of non-PD. 
PD detection will be disabled on port.

When a port loses a non-PD (cable disconnected, etc.), it generates the following syslog message:

PoE: Port 1/1/21 lost non-PD, so enabling PD detection.

Examples

The following example disables non-PD detection.

device# configure terminal
device(config)# no inline power non-pd-detection enable

The following example enables non-PD detection.

device# configure terminal
device(config)# inline power non-pd-detection enable
Warning: Enabling or disabling non-PD detection requires reload or 
disable/enable of ports with existing non-PDs.
Warning: Enabling this configuration also has following limitation:
All ports of a multi-port PD must be connected to one unit only so 
that a LAG configured does not span more than a single unit.
device(config)# write memory
device(config)# exit
device# reload
