Q: netinstall broken across multiple switches

we are using netinstall to image mac mini's in our network. when they are the same l2 switch in the same vlan they are able to see the images they can use. when we move them to another switch in the same l2 network in the same vlan they are unable to see the images they can use. is there something that is required between the l2 switches for this to work correctly? thank you in advance

Mac mini, OS X Server

    The switches need to forward DHCP packets between the server and client. See

    From a switch that has the issue, Can you ping the server from the client?

     

    Like cdhw said you probable need to configure an IP Helper to forward DHCP requests to the IP address of your server.

     

    As an example, on a cisco switch it would look some thing like this in the switch configuration.

     

    enable

    configer terminal

    ip helper-address 172.16.1.2

    exit

    exit

    write

     

    replace 172.16.1.2 with the IP address of the mac mini server.

     

    The network admin is probale already using an ip helper-address for the network DHCP server. He may be concerned that doing this could cause problem for the network. Just stress you can have multiple IP helpers it won't cause an issue long as you haven't enabled DHCP as OS X Server Service it shouldn't cause any issues. So promise him you won't.
