PoE configuration task list
You can configure a PoE interface by using either of the following methods:
• At the command line interface (CLI).
• Through configuring the PoE profile and applying the PoE profile to the PoE interface.
To configure a single PoE interface, configure it at the CLI. To configure PoE interfaces in batches, use the
PoE profile. For a PoE configuration parameter of a PoE interface, you can only select one mode
(including modification and removal of a PoE interface).
Complete these tasks to configure PoE:
