Managing General System Settings
Purpose
Configure the port high power mode for connected-device
compatibility.
• legacy—Use this mode if the device can power up (more
than 12.95 Watts) with higher current and cannot
identify itself as Class 4 device.
• dot3at—Use this mode if the device is a Class 4 device
capable of figuring out power requirement through LLDP .
Set the per-port power limit.
• class—Allows the port to draw up to the advertised class
maximum power.
• none—Allows port to draw up to class 0 maximum power
in low power mode and class 4 maximum power in high
power mode.
limit
• user-defined
defined configured value. The range of
31200 milliwatts.
Set the power-management mode for the port. This
setting overrides the mode set for the switch in global
configuration mode.
• 802.3af-only—IEEE 802.3af detection scheme is used.
• 802.3af+legacy—IEEE 802.3af 4point detection scheme
is used and when it fails to detect a connected PD, legacy
capacitive detection is used.
• legacy-only—only legacy capacitive detection scheme is
used.
Configure the PD disconnect type for the port.
Specify the technique for carrying power over the cabling:
• alternative-a—Power is carried over the same wire pairs as
the data.
• alternative-b—Power is carried over unused wire pairs in
the cable.
Provide a description to represent the type of device
connected to the port.
