WAP371 - Bonjour Enable / Disable (mDNSResponder ERROR: getOptRdata - unknown opt 65002)

[dreamcom-07]

Dear All,

we have some WAP371 WLAN installations at customer and ourselves. Always in Single Point Setup.
The smallest installation has 2 points, the largest has 6 Points.

All installations have the latest Firmware Version (1.1.2.3).

We have tried several times to set up Bonjour. Whenever we have enabled Bonjour there are masses of error Messages (at each access point - SinglePointSetup). In Addition almost all clients have Problems - sign permanently on the SSID on and off.

If we look at the logfile, we see the following error message (many):
 

Feb 25 2015 08:44:13	err	mDNSResponder	ERROR: getOptRdata - unknown opt 65002
Feb 25 2015 08:44:13	err	mDNSResponder	ERROR: getOptRdata - unknown opt 65002
Feb 25 2015 08:44:03	err	mDNSResponder	ERROR: getOptRdata - unknown opt 65002

Only when we turn off the Bonjour error message disappears.
Somebody has an idea which has to be done?

Thanks
Janis

My name Eric Moyers. I am an Engineer in the Small Business Support Center.

I am sorry to hear that you are experiencing this issue. 

This is actually related to a problem that originates within something that Apple changed in their Bonjour Sleep Proxy. Customer can read more about the Bonjour Sleep Proxy here: http://en.wikipedia.org/wiki/Sleep_Proxy_Service

For those that are interested there is a page for helping troubleshoot the issue located here: http://stuartcheshire.org/SleepProxy/index.html

Here is another article: http://www.dslreports.com/forum/r27042506-any-one-know-what-this-error-is

Normally the error message that I see is " mDNSResponder: ERROR: getOptRdata - unknown opt 4"

I personally have only recently started seeing the "ERROR: getOptRdata - unknown opt 65002".

I would also make sure that WMM is enabled on your Wireless routers and or Access Points.

What I usually tell customers is that if they experience this issue they should disable bonjour on the WAP. You can also follow-up with Apple on this issue.

Hi Eric,

I experienced the same issue with two wap121; can you conferm that disable bonjour will not interfere with SinglePointSetup?

Thankyou.

[Eric Moyers]

Yes disabling Bonjour should have no effects on "SPS"
