I am runing IOS 12.4(20)T3 on the Cisco 881 router. I am trying to enable the inline power on the interface fa0. I have the inline power source hook up the to router and the phone hook up to the port. I tried both Cisco phone and Nortel IP phone on both fa0 and fa1. But nothing is happening. From the documentation it should be auto detect. Command reference shows inline power command is
Router(config-if)# power inline auto/never
But there is no such option in the CLI. Can someone please tell me what I should do to enable the inline power. Thanks.
