Replaced GS724Tv4 with GS728TXP and AirPrint Will No Longer Work

Hi,

I had a working configuration with IGMP snooping enabled per directions found in the forum. All mdns functions on the network were working. Yesterday I replaced my GS724Tv4 with a GS728TXP running firmware 6.6.4.28.

I configured IGMP Snooping, Querier and router as I have always. Airprint is no longer working on wired printers connected to this switch.

I have 3 WAC510 Access points connected to a MS510TXUP. The MS510TXUP is connected via SFP+ to the GS728TXP. The network is configured just like I had it when AirPrint was working the only change is the GS724Tv4 was replaced with a GS728TXP.

Is there an issue with IGMP snooping on the GS728TXP and current firmware?

Quick update. I was provided with a pre-release firmware for testing. The firmware fixes the issue I was encountering. I assume it will be released publicly soon.

Just a quick follow-up.

Disabling IGMP snooping status on just the GS728TXP immediately brings the printer back on AirPrint. No changes needed on the other switches or wireless access points that I am using to print through.

  I found this as a known issue for the GC728XP:
  
  When either the IGMP or MLD snooping is enabled on a VLAN or globally, unknown multicast packets will be dropped for both IPv4 and IPv6.
  Workaround: Disable both IGMP snooping and MLD snooping.
  This sounds very much like what I am experiencing. These switches look very similar from a feature standpoint. Can someone at NETGEAR confirm if this will be fixed? I submitted a ticket as well.
  
  Thanks,
  Chad

    cwagz,
    
    Since you have already opened a support ticket with the NETGEAR Support Team about your concern, it would be best to wait for their response. You may want to share here the progress of your support ticket as well.
