Chapter 14 Configuring Power over Ethernet
Enhanced Power PoE Support on the E-Series Chassis
The following example shows how to automatically enable power on both signal and spare pairs from
switch port gigabit ethernet 2/1:
Switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# interface gigabitethernet 2/1
Switch(config-if)# power inline four-pair forced
Switch(config-if)# shutdown
Switch(config-if)# no shutdown
Switch(config-if)# end
Switch#
Do not enter this command if the end-device is incapable of sourcing inline power on the spare pair or
if the end-device supports the CDP or LLDP extensions for UPOE.
