Hello @choda489,

Fiber-optic media ont Te 0/0/24?

The speed/duplex and negotiation commands are meant for copper media. The fiber-optic media always operate as 1000 Mbps with full auto negotiation

Hello @choda489,

Please provide the output of that command:

show interface Te0/0/24 transceiver

OK @choda489 

Interface need to be up/up to configure what you want.

@choda489 

Coper or fiber? On your output, the media type is unknown.

Is auto negotiation needed if i am using a fiber-optic media for 10000Mbps?
