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 Laurent,
changing the IGMP config was more try and error. I'll set it back to default if somebody tells me what they are. Unfortunately, it is not an option the reset the entire switch to factory defaults.
Best, Stephan

Hi Laurent,
thanks for your detailed instructions. That helped! When switching back the topology to the Switch A – M4300 – Switch B setup, all devices on Switch B can now see the printer on Switch A via Bonjour/mDNS.
Not sure how to continue. My issue seems to be resolved but I'd really love to see some instructions and explanations in the manual. Currently, it just reads
A Mac OS device that supports Bonjour can discover the switch in the network so that you
can find the switch IP address and log in to the local browser interface of the switch. Bonjour is enabled by default. You can disable Bonjour for security reasons.Fantastic support, Laurent, by the way! :-)
Best, Stephan
Hi Stephan
Good news, in your case the default IGMP Snooping / Querier / Fast Leave configuration for VLAN 1 on an M4300 core switch - as well as the default Bonjour management enabled feature - were necessary to carry Bonjour/mDNS packets from switches to other switches via the M4300 switch running 12.0.7.12 in your network. This is good information for the Community. Yes, this is right, let me work on our technical documentation, we shall explain this in the manual and online.
If ever your concern has been addressed or resolved, I encourage you to mark the appropriate reply as the “Accepted Solution” so others can be confident in benefiting from the solution. The NETGEAR Community looks forward to hearing from you and being a helpful resource in the future!
