power inline
compatible
This command allows the switch to detect and provide power to powered devices
that were designed prior to the IEEE 802.3af PoE standard. Use the no form to
disable this feature.
Syntax
[no] power inline compatible unit
unit - Unit identifier. (Range: 1)
Default Setting
Disabled
Command Mode
Global Configuration
Command Usage
◆ The switch automatically detects attached PoE devices by periodically
transmitting test voltages that over the Gigabit Ethernet copper-media ports.
When an IEEE 802.3af or 802.3at compatible device is plugged into one of these
ports, the powered device reflects the test voltage back to the switch, which
may then turn on the power to this device. When the power inline compatible
command is used, this switch can detect IEEE 802.3af or 802.3at compliant
devices and the more recent 802.3af non-compliant devices that also reflect
the test voltages back to the switch. It cannot detect other legacy devices that
do not reflect back the test voltages.
◆ For legacy devices to be supported by this switch, they must be able to accept
power over the data pairs connected to the RJ-45 ports.
Example
Console(config)#power inline compatible
Console(config)#
power inline
maximum allocation
mode
This command sets the maximum power allocation mode based on PD (powered
device) class or user configuration. Use the no form to restore the default setting.
Syntax
power inline maximum allocation mode {class | user} unit
no power inline maximum allocation mode unit
class - Power allocation is based on device classification.
user - Power allocation is based on user configuration as defined in the
power mainpower maximum allocation Global Configuration command or
the power inline maximum allocation Interface Configuration command.
unit - Unit identifier. (Range: 1)
