power inline
To configure the inline power administrative mode on an interface, use the power inline Interface Configuration mode command.

power inline limit
To configure the power limit per port on an interface, use the power inline limit Interface Configuration mode command. To return to default, use the no form of the command.

Interface (Ethernet) Configuration mode
User Guidelines
The operational power limit is the minimum of the configured power limit value and the maximum power capability on port. For example, if the configured value is higher than 15.4W on a PoE port, the operational power limit is 15.4W.
Example
The following example sets inline power on a port.
switchxxxxxx(config)# interface te1/0/1switchxxxxxx(config-if)# power inline limit 2222 |

Syntax
power inline limit-mode {class | port} no power inline limit-mode
Parameters
- class—The power limit of a port is based on the class of the PD (Power Device) as detected during the classification process
- port—The power limit of a port is fixed regardless of the class of the discovered PD.
Default Configuration
The default value is port
Command Mode
Global Configuration mode
User Guidelines
Changing the PoE limit mode of the system will turn the power OFF and ON for all PoE ports.
Example
The following example sets the power limit to class.
switchxxxxxx(config)# power inline limit-mode class "Changing the PoE limit mode of the system will turn the power OFF and ON for all PoE ports. Are you sure? [y/n]" |
show power inline
