Configuration Guidelines
By default, EnergyWise is disabled on the switch.
If you enter the no energywise level command, the switch does not immediately change the power level
to the default. The power level changes when the switch restarts or when you enter the energywise level
level command.
For a switch with PoE ports, such as a PoE-capable switch:
• When you add the switch to a domain, EnergyWise is enabled on the switch and all the PoE switch
ports.
• Use the energywise level 0 interface configuration command to power off a PoE port.
• You cannot use the energywise level 0 global configuration command to power off the switch.
If a port is in the error-disabled state:
• It appears as an EnergyWise entity in the show command output and in the collect query results. The
query results show that the port uses 0 W.
• It does not respond to a set query.
For recurring events:
• Specify time in the 24-hour format. For example, to set 0634
–
As a specific time, enter the energywise level level recurrence importance importance at 34
6 * * * interface configuration command.
–
In a time range, enter the absolute start 06:34 * * 2009 and the periodic daily 06:34 time-range
configuration commands.
• The time zone is based on the end point.
–
If EnergyWise is not running on the end point (for example, a PoE end point), the specified time
is based on the switch time zone.
–
If an agent or client is running on the end point, the specified time is based on the end-point
time zone.
• If you configure the switch to power on an end point or a PoE port at a specific time, it powers on
within 1 minute, for example, between 0700 and 0701.
• If you configure the same recurring event for multiple end points, they all power on within 1 minute.
Note See the Release Notes for Cisco EnergyWise, EnergyWise Phase 2 on Cisco.com for software
releases with Cisco EnergyWise Phase 2.
• When you use the day_of_month and the day_of_week in the energywise level level recurrence
importance importance at minute hour day_of_month month day_of_week interface configuration
command in an EnergyWise Phase 2 software release:
–
The recurring event occurs when either the day_of_month or the day_of_week occurs first in
releases earlier than the EnergyWise Phase 2 releases.
If you specify both the day_of_month and the day_of_week, the event occurs when either the
day_of_month or the day_of_week is first.
If you specify the day_of_month and use a wildcard (*) for the day_of_week, the event occurs
on the day_of_month.
