Cisco Catalyst 2960 Series User Manual

PurposeCommand or Action
• auto—Enables powered-device detection. If enough power is available,
automatically allocates power to the PoE port after device detection.
This is the default setting.
Example:
Switch(config-if)# power inline
auto
• max max-wattage—Limits the power allowed on the port. If no value
is specified, the maximum is allowed.
• max max-wattage—Limits the power allowed on the port. The range
is 4000 to 30000 mW. If no value is specified, the maximum is allowed.
• never —Disables device detection, and disable power to the port.
If a port has a Cisco powered device connected to it, do not use the
power inline never command to configure the port. A false link-up
can occur, placing the port into the error-disabled state.
Note
• static—Enables powered-device detection. Pre-allocate (reserve) power
for a port before the switch discovers the powered device. The switch
reserves power for this port even when no device is connected and
guarantees that power will be provided upon device detection.
The switch allocates power to a port configured in static mode before it
allocates power to a port configured in auto mode.
Returns to privileged EXEC mode.end
Example:
Switch(config-if)# end
Step 5
Displays PoE status for a switch or a switch stack, for the specified interface,
or for a specified stack member.

Step 6
Example:
Switch# show power inline
The module switch-number keywords are supported only on stacking-capable
switches.

Fast POE
Fast PoE - This feature remembers the last power drawn from a particular PSE port and switches on power
the moment AC power is plugged in (within 15 to 20 seconds of switching on power) without waiting for IOS
to boot up. When poe-ha is enabled on a particular port, the switch on a recovery after power failure, provides
power to the connected endpoint devices within short duration before even the IOS forwarding starts up.
