The PoE PD communicates through the Data Link Layer (DLL) classification instead of
Physical Layer (high power mode). Hence, the PoE+ capable devices can deliver power
greater than 15.4 watts for each port.
You can configure the PoE PD detection type (802.3at or 802.3at_and_legacy) to support a
DLL classification for communication. The Data Link Layer classification provides finer power
resolution and the ability for PSE and PD to participate in dynamic power allocation. The
allocated power to the PD can change one or more times during PD operation.

Change RADIUS password is available only in secure software builds.
You can enable or disable the Change RADIUS password feature. By default, this feature is
disabled. When Change RADIUS password feature is enabled, the server reports the
password expiry and system prompts you to create a new password.
