How to read active ethernet configuration in MQX 3.8?

namile — Tue, 18 Mar 2014 14:06:16 GMT

How can i read following information for an active ethernet device?

- IP Address, Netmask, Gateway, DNS server that are configured in the stack. This configuration can be static or dynamic(DHCP) assigned.

You can try the high level network interface management API: ipcfg_get_ip, it returns ip mask and gateway.

Please refer to MQX_RTCS_User_Guide.pdf

Have a great day,
Daniel

Looks like this function works only for DHCP not for static configuration.

Hi Rajesh,

When the DHCP is used the gateway and DNS data is fulfilled automatically. If are using a fix IP then you need to set those values with the functions ipcfg_add_dns_ip() and RTCS_gate_add(). Then the function ipcfg_get_ip() will be able to return all that. The function ipcfg_task_create() is used to know if the Ethernet link is active.

Thank you. Garabo. Did not work for me with static info.

Here is what the function looks like(in ipcfg.c source file).

/*FUNCTION*--------------------------------------------------------------
*
* Function Name : ipcfg_get_ip()
* Returned Value : TRUE and IP, mask and gateway, if successful
* Comments : Returns actual ip information from DHCP response, if any. <<=====
*
*END--------------------------------------------------------------------*/

boolean ipcfg_get_ip
    (
        uint_32                     device,
        IPCFG_IP_ADDRESS_DATA_PTR   data
    )
{
    if (device < IPCFG_DEVICE_COUNT)
    {
        if (ipcfg_data[device].actual_state != IPCFG_STATE_INIT)
        {
            *data = ipcfg_data[device].actual_ip_data;
            return TRUE;
        }
    }
    return FALSE;
}

Hi Rajesh,

Try the example code I am attaching here. Code is in httpdsrv.c. It is working as explained before.
