CC3120MOD: DNS addressing when there is a secondary DNS

Expert 3040 points

Part Number: CC3120MOD

I would like to ask you about the behavior of the driver of DNS addressing when there is a secondary DNS.

In programmers guide, page #90,

　Time.MaxResponseTime = 2000;

　Time.NumOfRetries = 30;

sl_NetAppDnsGetHostByName()

is this setting correct? if this is correct, even if secondary DNS sets, when primary DNS is offline, it is waiting for 1sec (until failing 30 times), we would like to set the smaller value than example = 30; is it no problem?

You can change the setting. This is just an example.

If you are concerned regarding the specific use case you can reduce the number of retries or the max timeout.

Reducing the timeout too much can cause the DNS query to fail (especially in a noisy environment).

Hi Kobi,

Thank you very much, customer checked that

　Time.MaxResponseTime = 2000;

　Time.NumOfRetries = 3;

under this condition, no problem is confirmed.

Best Regards, NY
