Table 109: PoE Port Configuration Fields
Field
Description
Interface
The interface associated with the rest of the data in the row. When configuring
PoE settings, this field identifies the interface(s) being configured.
Admin Mode
Whether PoE is administratively enabled or disabled on the interface.
Priority
The priority of the port when allocating available power. Power is delivered to
the higher priority ports when needed before providing it to the lower priority
ports. Possible values are Critical, High, and Low.
High Power Mode
When enabled, the port supports the PoE+ power standard, which allows for
providing up to 30W of power. When disabled, the port supports the original
PoE standard only, which allows for providing up to 15.4W of power.
Power Limit Type
The type of power limiting used for the port, which can be one of the following:
•
Class – The device class determines the power limit. The switch learns the
class of the device through the receipt of
messages.
•
User – The power limit is user defined, overriding the LLDP information.
When set, the Power Limit field is enabled.
Power Limit
The power limit for the port, which can be specified. This field displays only when
Power Limit Type
is set to User.
Detection Type
The protocol(s) that can be used to detect the presence of a PD when connected
to a PoE port. The IEEE specification 802.3af (Dot3af) specifies various detection
algorithms. Some PDs use legacy detection algorithms that were in place prior to
the 802.3af standard, which can be one of the following:
•
Legacy – The switch uses a legacy detection scheme not defined in 802.3af.
•
4Pt-Dot3af – The switch uses the 802.3af 4-point detection scheme only.
•
4Pt- Legacy – The switch uses the 802.3af 4-point detection
scheme, followed by the legacy detection scheme.
•
2Pt-Dot3af – The switch uses the 802.3af 2-point detection scheme.
•
2Pt- Legacy – The switch uses the 802.3af 2-point detection
scheme, followed by the legacy detection scheme.
•
None – No detection is performed.
Timer Schedule
The time range from the list of time ranges configured on the system.
