Re: ME3400 unable to change duplex setting


I'm not familiar with this platform, but on Catalyst switches you need to configure media-type {rj45|sfp} on dual-purpose ports before you can configure media-specific settings like duplex mode.



Re: ME3400 unable to change duplex setting

Configuration Guide:

Please keep in mind that there will be short outages when you change the media-type and the duplex-mode, because the port has to re-initialize.

ME3400EG-2CS-AYou need to set


You need to set the media-type to RJ45 under the interface. Once done you then have the option of speed and duplex settings.

Setting media-type to auto-select or sfp result in not being able to manually apply speed and duplex settings.
