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 ?
