Use the show run command to view whether support for PoE legacy power-consuming devices is
enabled or disabled.
The following example turns off support for legacy inline power on an FSX 800.
SX800-3J31-u7(config)# leg
legacy-inline-power set legacy (capacitance-based) PD detection -
default
SX800-3J31-u7(config)# legacy-inline-power
DECIMAL Slot number
<cr>
SX800-3J31-u7(config)# legacy-inline-power 8
SX800-3J31-u7(config)# no leg
legacy-inline-power set legacy (capacitance-based) PD detection -
default
SX800-3J31-u7(config)# no legacy-inline-power 8
The following example turns off legacy inline power for a single stack unit.
ICX7250-24-3J32-u12(config)# no legacy-inline-power
The following example turns off legacy inline power support on the entire stack.
ICX7250-24-3J32# configure terminal
ICX7250-24-3J32 (config)# stack unit 12
ICX7250-24-3J32-u12(config)# no legacy-inline-power
Enabling the detection of PoE power requirements advertised through
CDP
Many power-consuming devices, such as Cisco VoIP phones and other vendors’ devices, use the Cisco
Discovery Protocol (CDP) to advertise their power requirements to power-sourcing devices, such as
Brocade PoE devices. Brocade power-sourcing equipment is compatible with Cisco and other vendors’
power consuming devices and can detect and process power requirements for these devices
automatically.
NOTE
If you configure a port with a maximum power level or a power class for a power-consuming device, the
power level or power class takes precedence over the CDP power requirement. If you want a device to
adhere to the CDP power requirement, do not configure a power level or power class on the associated
port.
Command syntax for PoE power requirements
To enable the Brocade device to detect CDP power requirements, enter the following commands.
device# configure terminal
device(config)# cdp run
Syntax: [no] cdp run
Use the no form of the command to disable the detection of CDP power requirements.
