IGMP Snooping breaks Bonjour / AirPrint

Hi,

 

since we use a GS116Ev2 switch in our network we constantly had problem using AirPrint or other services that rely on Bonjour. Sometimes discovery of the AirPrint capable printers worked. Sometimes not.

 

I figured out that the IGMP Snooping option is the root of this problem. Once this option was disabled, everything worked stable.

 

Is Netgear aware of this problem? And will be a new firmware fixing this?

 

Thanks!

Hi wodo,

 

Welcome to the community! 🙂 

 

So far , I have not found any issues pertaining to IGMP Snooping that it breaks Bonjour/AirPrint when its enabled on the GS116Ev2.  Kindly answer the questions below:

 

a. What is the current firmware version of your GS116Ev2?

b. Does same problem occur if you remove the GS116Ev2 from your current network setup?

c. Have you tried to perform a factory reset on the GS116Ev2 then reconfigure it from scratch and check if same problem occurs when IGMP Snooping is enabled?

Here are my answers:

 

a.) 2.0.1.26

b.) No. Without the Netgear the problem does not occur.

c.) Yes. Factory Reset did not help.

 

I have two AirPort Express connected to the Netgear. The AirPrint devices are connected to the WLANs of these AirPort Express. When the AirPort Express stations are rebooted, AirPrint works for a few minuten across the NetGear switch. But then the AirPrint devices start to disappear and are no longer discoverable across the GS116E.

Hi wodo,

 

Can you try to downgrade the firmware to v2.0.1.24 then check if same problem will occur.  Be sure to perform a factory reset on the GS116Ev2 after a successful downgrade of the firmware then reconfigure it from scratch.

Hi,

 

Just wanted to let you know that I'm facing a very similar issue with a M5300-28G-POE+ switch running the latest firmware version.

 

For the Negear guys: I have a ticket with Netgear about this issue: 26900588

I've done the downgrade to 2.0.1.24 with factroy reset. Same behavior.

 

What I figured out is that the problem occurs when the AirPrint devices are connected to the AirPort Extreme. As soon as a device is behind an AirPort Extreme, the problem starts and only devices that are connected to the same AirPort can discover these the AirPrint printers. So it seems to be some incompatibility between the Netgear IGMP snooping implementation and the AirPort Extreme. The AirPort Extremes we are using have the latest firmwares installed as well (7.6.4 and 7.7.3 depending on the hardware version).

Hi wodo,

 

I think it would be best that you open an online case with NETGEAR Support at anytime.  Let them know about your concern as it might be a compatibility issue between the GS116Ev2 and the AirPort Extreme.
