Monitoring PD
When a PSE starts or ends supplying power to a PD, the system will send a trap message.
Configuring PoE Interface through PoE Profile
You can configure a PoE interface in either of the following two ways:
z Using command lines.
z Using a PoE profile, and applying the PoE profile to the specified PoE interface(s).
When configuring a single PoE interface, you can use command lines; when you configure PoE
interfaces in batches, you can use a PoE profile.
A PoE profile is a collection of configurations, containing multiple PoE features. On large-scale
networks, you can apply a PoE profile to multiple PoE interfaces, and thus these interfaces
have the same PoE features. If the PoE interface connecting to a PD changes to another one,
you just need to apply the PoE profile applied on the originally connected interface to the
currently connected interface instead of reconfiguring the features defined in the PoE profile
one by one, thus simplifying the PoE configurations.
You can define PoE configurations based on each PD, save the configurations for different PDs
into different PoE profiles, and apply the PoE profiles to the access interfaces of PDs
accordingly.
