Parameter
slot-number: Number of the slot where the board resides.
Description
Use the poe legacy enable slot command to enable the board to perform
PoE-compatibility detection for the remote PDs.
Use the undo poe legacy slot command to disable PoE-compatibility detection for the
remote PDs.
By default, PoE-compatibility detection for PDs is disabled on the board.
Through the PoE-compatibility detection, the switch can detect the PDs incompatible
with IEEE802.3af and supply power to them.
Caution:
PoE-compatibility detection process is very slow and has impact on the system
performance, so you are recommended not to enable the PoE-compatibility detection
on a board if all PDs connected are IEEE802.3af-compatible.
