PoE的接口配置預設都是Auto模式
PoE設備接入到PoE交換機上,交換機就能夠自動的識別對方是否需要受電,另外還能夠判斷功率
察看PoE狀態
Switch# show power inline
Interface Admin Oper Power(Watts) Device Class Max
--------- ------ ---------- ------- ------------
Fa0/1 auto off 0.0 n/a n/a 15.4
Fa0/2 auto on 10.3 IP Phone CP-7970G 3 15.4
Admin模式均是Auto,如要更改指令如下:
Switch(config-if)#power inline ?
auto Automatically detect and power inline devices
delay Inline power delay timer setting
never Never apply inline power
手動強制設置交換機的PoE端口功率
wattage Specify the power that the switch budgets for the port. The range is 4000
to 15400 milliwatts.
The default power on each Power over Ethernet (PoE) port is 15400 milliwatts.
每個PoE的端口設定為5000毫瓦
Switch(config)# power inline consumption default 5000
針對特定PoE的端口設定為12000毫瓦
Switch(config)# interface gigabitethernet1/0/2
Switch(config-if)# power inline consumption default 12000
