Configuring PoE Operation
8
Syntax: interface [e] < port-list > power [ critical | high | low ]
Reconfigures the PoE priority level on < port-list >. For a given
level, the switch automatically prioritizes ports by port
number (in ascending order). If there is not enough power
available to provision all active PoE ports at a given priority
level, then the lowest-numbered port at that level will be
provisioned first, and so on. The switch invokes configured
PoE priorities only when it cannot provision all active PoE
ports.
Critical: Specifies the first priority PoE support for < port-
•
list >. The switch provisions active PoE ports at this level
before PDs connected to any other ports.
High: Specifies the second priority PoE support for
•
< port-list >. The switch provisions active PoE ports at this
level before PDs connected to Low-priority ports.
•
Low (the default): Specifies the third support priority for
< port-list >. The switch provisions active PoE ports at this
level only if there is power available after provisioning any
active PoE ports at the higher priority levels.
