Configuring PoE Interfaces Through a PoE Configuration File
A PoE configuration file is used to configure at the same time multiple PoE interfaces with the same
attributes to simplify operations. This configuration method is a supplement to the command line
configuration.
The PoE configuration file features:
You can create multiple PoE configuration files for different user group and apply the specific PoE
configuration file to the port a user group uses.
When you use a PD on a port with PoE configuration file being applied, the configuration in the PoE
configuration file will be enabled.
Commands in a PoE configuration file are called configurations.
