    Hi,

     

    Is there any special configuration required in juniper switches to have MAC machines to communicate each other. The issue is that the guy who supporting MAC machine complaints that the MAC clients can not see the services configured between them. Could someone help me with any advice. These clients are distributed across different juniper switches.

     

    Thanks

    Can you give more detail around what isn't working?  switching is switching, regardless of the client machine.  No special configuration is required on the network gear to support a Mac over any other architecture.

    Hi,

     

    Thanks for lokking in ti this. Clients are not seeing each other from MAC OS. I think they use multcast for service discovery (Zero configuration). They all in same vlan. In some switches igmp snooping is enabled.

     

     

    Thanks

    What hardware and software version are you using?  I have a few mac's on my network, and haven't seen any issues, but I don't use zeroconf.  I have everything assigned via a DHCP server

    Do you have IGMP-SNOOPING enabled?  There was a bug with igmp-snooping previously  in the 10.x train (can't remember the exact code revision) that caused 224.0.0.x/24 igmp groups to not be flooded as they should be.

     

    If its enabled, try disabling igmp-snooping "deactivate protocols igmp-snooping' and see if they helps out.
