What can be done to dynamically set the PoE Priority on a switch port when deploying IP cameras APs. and other PoE devices?

Device profiling on ArubaOS-CX switches enables the identification of connected devices, such as IP cameras or Access Points, using methods like LLDP or DHCP fingerprinting. Once a device is identified and classified, a specific role can be dynamically assigned to the switch port. This role acts as a container for various configuration attributes, including the PoE priority (critical, high, or low). This mechanism allows an administrator to create policies that automatically assign a higher PoE priority to critical devices like security cameras, ensuring they are the last to lose power in a limited power scenario.

A. Enable Quick PoE on the switch modules: Quick PoE provides power to a port immediately upon link-up, even before the switch has fully booted. It concerns the speed of initial power delivery, not the ongoing power priority.
C. Configure PoE power management to Class-based Mode: This mode allocates a fixed amount of power based on the device's IEEE PoE class. It manages the power budget allocation, not the priority of which port loses power first.
D. Configure PoE power management to Dynamic Mode: This mode allocates power based on the device's actual, real-time consumption, which optimizes the switch's power budget. It does not set the port's priority.

1. ArubaOS-CX 10.11 Security Guide, Page 289, "Device profiling" section: "Device profiling enables the switch to identify the type of device that is connected to a port... Based on the device type, a user role can be applied to the device to place it in a specific VLAN and apply a unique set of policies."

2. ArubaOS-CX 10.11 Security Guide, Page 321, "Configuring a role" section: This section details the attributes that can be configured within a role. The associated command reference confirms poe-priority is a configurable attribute within a role.

3. ArubaOS-CX 10.11 Command-Line Interface Guide, Page 4889, role command details: The guide shows the syntax role poe-priority , confirming that PoE priority can be set as part of a role, which is then applied dynamically via device profiling.
