2.2.2 Configuring the PoE Parameters Using the Profile
Follow these steps to configure the PoE profile:
Step 1
configure
Enter global configuration mode.
Step 2
power profile
name
[ supply {
enable
|
disable
} [ priority {
low
|
middle
|
high
} [ consumption {
power-limit
|
auto
|
class1
|
class2
|
class3
|
class4
} ] ] ]
Create a PoE profile for the switch. In a profile, the PoE status, PoE priority and power limit
are configured. You can bind a profile to the corresponding port to quickly configure the PoE
function.
name
: Specify a name for the PoE profile. It ranges from 1 to 16 characters. If the name
contains spaces, enclose the name in double quotes.
enable
|
disable
: Specify the PoE status for the profile. By default, it is enable.
low
|
middle
|
high
: Select the priority level for the profile. When the supply power exceeds the
system power limit, the switch will power off PDs on low-priority ports to ensure stable running
of other PDs.
power-limit | auto | class1 | class2 | class3 | class4:
Select or enter the maximum power the
corresponding port can supply. The following options are provided:
Auto
represents that the
switch will assign a value of maximum power automatically.
Class1
represents 4W,
Class2
represents 7W,
Class3
represents 15.4W and
Class4
represents 30W or you can enter a value
manually. The value ranges from 1 to 300. It is in the unit of 0.1 watt. For instance, if you want to
configure the maximum power as 5W, you should enter 50.
Step 3
interface {
fastEthernet
port
| range fastEthernet
port-list
| gigabitEthernet
port
| range
gigabitEthernet
port-list
}
Enter Interface Configuration mode.
port
: Specify the Ethernet port number, for example 1/0/1.
port-list:
Specify the list of Ethernet ports, for example 1/0/1-3, 1/0/5.
Step 4
power inline profile
name
Bind a PoE profile to the desired port. If one profile is selected, you will not be able to modify
PoE status, PoE priority or power limit manually.
name
: Specify the name of the PoE profile. If the name contains spaces, enclose the name in
double quotes.
