Power Over Ethernet Commands—Summit 300 and 400-24p Switches and Alpine PoE Module
enable inline-power legacy
enable inline-power legacy
Description
Enables legacy (802.3af compliant) devices to be detected by the PoE subsystem.
NOTE
This command is available only for the Summit 300-24 and 400-24p switches.
Syntax Description
This command has no arguments or variables.
Default
Disabled
Usage Guidelines
The Summit 300-24 or 400-24p switch can power devices that are compliant to the IEEE 802.3af Power
over Ethernet standard. The
enable inline-power legacy
command allows PoE devices built before
the standard was approved to be powered.
If all the devices connected to the switch are 802.3af standards compliant, it is advised to keep the
default setting of disabled for legacy device support.
You can determine whether a device connected to the switch is standards compliant or not by using the
show inline-power info [port <portlist | detail port <portlist]
command. The detailed
status line shows if the device is 802.3af standards compliant.
Sample output from the show inline-power info detail ports command follows:
Summi t 300-24:3 # show inline-power info detail ports 5
PORT - 5
