By default, power inline is disabled. Port Prioritization To specify the priority on a particular interface on the port extender, use the power inline priority command. When you reduce the inline power available in a port extender, the lower priority interfaces are disabled initially then the higher priority interfaces are disabled. Between equal priority ports, the port number determines which port is assigned the higher priority. Port 0 has the highest priority and port 47 has the lowest priority. For more information, see Managing Power Priorities and Managing Ports using Power Priority and the Power Budget. On a port extender interface, you can configure one of the following priority levels: critical, high, and low. By default, all ports are set to low. When you reduce the available inline power, the order of priority for disabling the inline power to the interfaces is as follows: 1 Ports with low priority are shut down first. 2 Ports with a high priority are shut down second. 3 Ports with a critical priority are shut down third. NOTE: When you configure the ports with the same priority levels, the port number determines which port has the highest priority (port 1 has the highest priority; port 48 has the lowest priority). The ports with the higher interface numbers for inline power disable first. The ports with the lower interface numbers have the highest priority. For example, if you configure ports 1, 2, 47, and 48 with a low priority and the inline power available becomes less, PoE is disabled on the ports in the following order: a port 48 b port 47 c port 2 d port 1 NOTE: Avoid allocating more power than necessary to a port because allocated power is made unavailable to other ports regardless of whether it is consumed when using the power inline max_milliwatts command. Typical IP phones use 3 to 10 Watts. Power over Ethernet (PoE) 877
