Setting the inline power priority for a PoE port
slot number then by port number, provided enough power is available for the ports. For example,
PoE port 1/11 should receive power before PoE port 2/1. However, if PoE port 1/11 needs 12
watts of power and PoE port 2/1 needs 10 watts of power, and 11 watts of power become
available on the device, the FastIron PoE device will allocate the power to port 2/1 because it does
not have sufficient power for port 1/11.
You can configure an inline power priority on PoE ports, whereby ports with a higher inline power
priority will take precedence over ports with a low inline power priority. For example, if a new PoE
port comes online and the port is configured with a high priority, if necessary (if power is already
fully allocated to power consuming devices), the FastIron PoE device will remove power from a PoE
port or ports that have a lower priority and allocate the power to the PoE port that has the higher
value.
Ports that are configured with the same inline power priority are given precedence based on the
slot number and port number in ascending order, provided enough power is available for the port.
For example, if both PoE port 1/2 and PoE port 2/1 have a high inline power priority value, PoE port
1/2 will receive power before PoE port 2/1. However, if PoE port 1/2 needs 12 watts of power and
PoE port 2/1 needs 10 watts of power, and 11 watts of power become available on the device, the
FastIron PoE device will allocate the power to PoE port 2/1 because it does not have sufficient
power for port 1/2. By default, all ports are configured with a low inline power priority.
Command syntax for setting the inline
power priority for a PoE port
To configure an inline power priority for a PoE port on a FastIron PoE device, enter commands such
as the following.
Brocade#configure terminal
Brocade(config)# interface ethernet 1/1
Brocade(config-if-e1000-1/1)# inline power priority 2
These commands enable inline power on interface ethernet 1 in slot 1 and set the inline power
priority level to high.
Syntax: [no] inline power priority <priority num>
The priority <priority num> parameter is the inline power priority number. The default is 3 (low
priority). You can specify one of the following values:
• 3 – Low priority
• 2 – High priority
• 1 – Critical priority
Use the inline power command (without a priority number) to reset a port priority to the default
(low) priority.
Use the no inline power command to disable the port from receiving inline power.
For information about resetting the inline power priority, refer to “Resetting PoE parameters” on
page 675.
To view the inline power priority for all PoE ports, issue the show inline power command at the
Privileged EXEC level of the CLI. Refer to “Displaying PoE operational status” on page 675.
