You can augment the default prioritization using the command
[
no
]
power inline priority
{
critical
|
high
|
low
}, where
critical
is the highest priority, and
low
is the lowest. FTOS ignores any LLDP-MED priority on
this port if you configure a priority with this command. If you do not configure a port priority with this
command, FTOS honors any LLDP-MED priority.

In general, priority is assigned in this order:

If power must be terminated for some ports, the order in which ports are affected is based on priority. Ports
with the lowest priority are terminated first (see
