Chapter 6. Manage / Configure the Switch
30
For “Auto Negotiation” mode, the switch will disable port auto-negotiation function when the auto function of port
(in Port Configuration setting) is disabled.
For “Auto Detect” mode, the switch will always keep port auto-negotiation function ON but just modify its
attribution if auto function of port (in Port Configuration setting) is disabled.
For applications, you should select “Auto Detect”mode if the connected device is auto-negotiation enabled. (For
example, customer’s PC is auto-negotiation enable and you want to set his network connection to work at 10Mbps.)
And you can select “Auto Negotiation”mode if the connected device is auto-negotiation disabled (it is called forced
mode, sometimes). Some old TX-FX Converters needs to work in this mode because FX supports 100/Full forced
mode only. For most applications, “Auto Detect” mode is OK.
With “automode ?”, the sub-commands will be shown.
(config)# automode ?

automode detect command will set it to auto-detect mode.
automode negotiation command will set it to auto-negotiation mode.
