Power over Ethernet (PoE)
Switch models with 'P' suffix in the name support Power over Ethernet feature according to IEEE
802.3af (PoE) and IEEE 802.3at (PoE+) recommendations. Number of ports with PoE support and the total
supply power may vary for different models. For the detailed information on each switch model, see
Subsections 2.3 and 2.4.

Table 5.194 —Ethernet interface configuration mode commands
Command
Value/Default value
Action
power inline {auto | never}
/auto
This command allows to set the power supply system
operation mode for the interface.
-
auto
—enable the PoE-device discovery protocol for the
interface and enable the power supply.
-
never
—disable the PoE-device discovery protocol for the
interface and disable the power supply.
power inline powered-device
pd_type
pd_type:{1..24
characters}/not defined
Add the arbitrary PoE device description for easier device
administration.
no power inline
powered
-
device
Remove previously added PoE device description
power inline priority {critical
| high | low}
/low
Define the PoE interface priority during the power
management.
-
critical
—define the highest power supply priority When the
PoE system overload occurs, power supply for ports with such
priority will be cut off last.
-
high
—define the high power supply priority
-
low
—define the low power supply priority
no power inline priority
Restore the default priority value.
power inline limit
power
Power: {0..30000}/30000
mW
Define the power limit for the selected port.
no power inline limit
Restore the default power limit value.
The maximum power limit is set by default.
