How to configure IGMP Snooping for Bonjour
Dear community,
we ran two switches A and B until recently (both HP ProCurve, fully managed). A printer is connected to switch A, some desktops and Wifi access points are connected to switch B....
Hi Stephan
In the meantime, and without interfering with NETGEAR Tech-Support teams, please see how you can reconfigure the M4300 back to default for IGMP Multicast on VLAN 1 without factory defaulting the switch.
The below is with the GUI if you need CLI commands just let me know.
Log into the M4300 GUI, and click blue button APPLY before leaving each page below:
- Go to Switching\Multicast\IGMP Snooping\Configuration: have all three IGMP Snooping Configuration Admin Mode, Validate IGMP Header and Proxy Querier mode ENABLE
- Go to Switching\Multicast\IGMP Snooping\Interface Configuration: all interfaces should show DISABLE in Admin Mode
- Go to Switching\Multicast\IGMP Snooping\IGMP VLAN Configuration: we should show VLAN 1 (if not, we should add VLAN 1) and Admin Mode should show ENABLE, Fast Leave should show ENABLE, Membership interval 260, Maximum Response Time 10, Multicast Router Expiry Time 0, Report Suppression DISABLE and Proxy Querier ENABLE
- Go to Switching\Multicast\IGMP Snooping\Multicast Router Configuration: all interfaces should show DISABLE in Admin Mode
- Go to Switching\Multicast\IGMP Snooping\Multicast Router VLAN Configuration: it should be empty
- Go to Switching\Multicast\IGMP Snooping\Querier Configuration: Querier Admin Mode should show ENABLE, Snooping Querier Address should show 0.0.0.0 (used for querier election priority), IGMP Version 2, Query Interval(secs) 125 and Querier Expiry Interval(sec) 255
- Go to Switching\Multicast\IGMP Snooping\Querier VLAN Configuration: we should show VLAN 1 (if not, we should add VLAN 1) and Querier Election Participate Mode should show ENABLE, Querier VLAN Address should show 0.0.0.0 (used for querier election priority)
- Go back to Switching\Multicast\IGMP Snooping\Querier Configuration: now we should show VLAN 1 at the bottom of the page, under VLAN IDs Enabled for IGMP Snooping Querier
- Go to Maintenance\Save Config, or click the little "floppy disk" icon at the top of the page
With that, your M4300 should be back to default for its default IGMP Configuration on VLAN 1.

Hi, extremely sorry for your issue. We shall fix it asap.
Can you make sure the Bonjour feature is set to Enabled in 12.0.7.12?
Using the M4300 GUI:
1. Navigate to System > Management > Bonjour > Bonjour Configuration.
2. Set Admin Mode to Enable.
3. Click the blue Apply button.
Using the M4300 CLI:
enable
configure
bonjour run
exit
save
Please let us know, with 12.0.7.12 the Bonjour feature must be enabled to let mDNS packets go through.

Hi Laurent,
thanks for your feedback. Unfortunately it does not help, Bonjour/mDNS is still not working in the setup described above.
Best, Stephan
- Hi, sorry about that. I suspect an interop issue between A / B and the newly added M4300 core switch.
I'd like to make sure, before making you troubleshoot. Can you disconnect A and B, and connect your left printer and other right Access Points devices to the M4300 (as far as the port count lets you do that)? As you said it's Layer 2 and flat VLAN 1, nothing else should be done and Bonjour should work? Can you tell us?
If Bonjour works, then we have an IGMP issue between the new core and A /B. We shall fix it by configuring the IGMP Querier accordingly between the three switches. We will also control the Multicast Router mode in between A and B previously (maybe the ProCurve's do that). Again, sorry. Based on your response, we will evaluate the issue.
Regards,Hi Laurent,
hm… connecting the printer and one other device to the M4300 is challenging due to the locations. I'll try to arrange a test setup but cannot guarantee that I can manage it.
Stephan
Hi Stephan
OK sorry, if different locations I understand the challenge.
Then, we need to directly go to the troubleshooting. For this, we would need the following files:
- The switch A configuration file
- The switch B configuration file
- The M4300 core switch tech-support file when the problem occurs (To do so, you can use the Web GUI, go to Maintenance \ Export \ HTTP File Export and select Tech Support in the dropdown list).
I am going to send you my email address by private message. If you can send me these files, we should be able to understand where the problem resides and how to fix it.
Thanks in advance!
