The Source represents the power source being utilized by a PSE or PD device.
For a PSE device, it can run on its Primary Power Source or Backup Power
Source. If it is unknown what power supply the PSE device is using, this is indi-
cated as Unknown.
For a PD device, it can run on its local power supply or use the PSE as a power
source. It can also use both its local power supply and the PSE.
If it is unknown what power supply the PD device is using, this is indicated as
Unknown.
Power Priority represents the priority of the PD device, or the power priority asso-
ciated with the PSE type device's port that is sourcing the power. There are three
levels of power priority. The three levels (Critical, High and Low). If the power pri-
ority is unknown, this is indicated as Unknown.
The maximum power in watts required by a PD device from a PSE device, or the
minimum power a PSE device is capable of sourcing over a maximum length
cable based on its current configuration.
The maximum allowed value is 102.3 W. If the device indicates a value higher
than 102.3 W, this is represented as reserved.
The port on this switch which received the LLDP frame.
The link partner's maximum time that the transmit path can hold off sending data
after de-assertion of Lower Power Idle (LPI) mode. (Tw indicates Wake State
Time)
The link partner's time the receiver would like the transmitter to hold off to allow
time for it to wake from sleep.
The link partner's fallback receive Tw.
A receiving link partner may inform the transmitter of an alternate desired
Tw_sys_tx. Since a receiving link partner is likely to have discrete levels for sav-
ings, this provides the transmitter with additional information that it may use for a
more efficient allocation. Systems that do not implement this option use a default
that is the same as that of the Receive Tw_sys_tx. (Refer to IEEE 802.3az for fur-
ther information on these system variables.)
The link partner's Echo Tx Tw value.
The respective echo values shall be defined as the local link partner's reflection
(echo) of the remote link partner's respective values. When a local link partner
receives its echoed values from the remote link partner it can determine whether
or not the remote link partner has received, registered and processed its most
recent values. For example, if the local link partner receives echoed parameters
that do not match the values in its local MIB, then the local link partner infers that
the remote link partner's request was based on stale information.
The link partner's Echo Rx Tw value.
The resolved Tx Tw for this link (not the link partner). The resolved value that is
the actual tx wakeup time used for this link (based on EEE information exchanged
via LLDP).
