inline power non-pd-detection enable
By default, non-PD detection is enabled.
Global configuration mode
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.
- Configure the LAG for multiport PDs.
- Enable non-PD detection mode.
- 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.
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
