Interface Types
Configuring Power Consumption for Powered Devices on an Interface
When the switch detects a powered device on an interface, it provides the default power to the device.
When the switch receives a CDP packet from the powered device, the power is automatically negotiated
to a wattage required by the device. Normally, this automatic negotiation works well, and no further
configuration is required or recommended. However, you can specify the powered device's consumption
for a particular interface to provide extra functionality from your switch. This operation is useful when
CDP is disabled or not available.
To change the power consumption of a single powered device, follow these steps:
Command
Step 1 interface {fastethernet | gigabitethernet} slot/port
Step 2 [no] power inline consumption milli-watts
Step 3 end
Step 4 show power inline consumption {fastethernet |
gigabitethernet} slot/port
At a given time, you can use only one of the power negotiation protocols between CDP and LLDP. The
following examples show how to enable or disable the power negotiation protocols:
Switch(config)# [no] lldp run
Switch(config)# [no] cdp run
The Power Device(PD) and Power Source Equipment (PSE) should run the same power negotiation
Note
protocol to negotiate power.
Network Module Interfaces
The uplink ports on the 10-Gigabit service module and on the 10-Gigabit Ethernet network module are
labeled Te1/Gi2 and Te2/Gi4. These ports can operate at either 1 Gigabit per second or 10 Gigabits per
second. They are identified in software as gigabitethernet x/1/2 and x/1/4 and tengigabitethernet x/1/1
and x/1/2, with x being the switch number on Catalyst 3750-X stacks. The Catalyst 3560-X switch port
numbers are the same, with no switch number.
Network Services Module
The Catalyst 3750-X and 3560-X Network Services Module (C3KX-SM-10G) uplink slots support
either 1-Gigabit SFP modules or 10-Gigabit SFP+ modules. See the Installation Notes for the Catalyst
3750-X and 3560-X Network Modules for more details.
When you install a network services module in a Catalyst 3560-X or 3750-X switch, you can configure
the 1-Gigabit and 10-Gigabit Ethernet uplink ports for the same features as any other ports in the switch.
The network services module uplink ports also support Flexible NetFlow and switch-to-switch MACsec
uplink encryption (link layer security).

Purpose
Selects the interface to configure.
Sets the PoE consumption (in milliwatts) of the powered
device connected to a specific interface. The power
consumption can range from 4000 to 60000.
To reenable the automatic adjustment of consumption, use
the no keyword.
Exits configuration mode.
Displays the PoE consumption for the interface.
