we have a network using principally Cisco network device (Switchs and routers).
Currently all duplex setting and speed setting is set administratively on each device at both end. All servers connections have also there speed and duplex settings at both end.
Now we have someone in our team want to change all setting for auto-negotiation for everything (servers, routers and switches), his arguments it's more easy to manage and sometime auto-negotiation can help us to diagnostic some network problems or cabling problems.
On my knowledge, and it is what I had recently read in my CCNP certification guide, it is always a good practice to administratively set duplex and speed for network devices like switches and router and also for connection for servers to make sure all of them are always connect at the speed and duplex setting we want for thoses connections.
Which one of these practice is better to use, considering everything and why ?
Thanks a lot !
