Prioritizing Ports

When the total power requirements of the PDs exceed the total available
power of the switch, the switch denies power to one or more ports based
on port prioritization.To guarantee power to the most critical PDs before
any other PDs, the switch allows you to prioritize the ports for power
supply.
You can assign one of three priority levels to a port: Critical, High, and
Low. See "Port Prioritization" on page 253 for details. By default, all ports
are set to the Low priority level. To change the priority level, use the
POWER-INLINE PRIORITY command. Here is the format:
power-inline priority critical | high | low
To guarantee that the most critical PDs receive power, assign the highest
priority level to the PDs. See "POWER-INLINE PRIORITY" on page 278.
To reset the priority level to the default Low level, use the NO POWER-
INLINE PRIORITY command. See "NO POWER-INLINE PRIORITY" on
page 270.
This example assigns ports 1, 2, and 3 to the Critical priority level to
guarantee these ports receive power before any other ports with the High
or Low priority level:
awplus> enable
awplus# configure terminal
awplus(config)# interface port1.0.1-port1.0.3
awplus(config-if)# power-inline priority critical
This example assigns port 4 to port 10 to the High priority level so that the
ports receive power before any ports with the Low priority level:
awplus> enable
awplus# configure terminal
awplus(config)# interface port1.0.4-port1.0.10
awplus(config-if)# power-inline priority high
This example sets port 8 to the Low priority level:
awplus> enable
awplus# configure terminal
awplus(config)# interface port1.0.8
awplus(config-if)# no power-inline priority
