7 automode command
With the command, user can select the operation mode of port when “auto” is set to
disabled.
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.
