MAS + Distributed, L3 subnet + DHCP reservation

  • 1.  MAS + Distributed, L3 subnet + DHCP reservation

    Posted Oct 02, 2015 01:56 PM

    I have got a deployment where I am using distributed, L3 from our Aruba switch to serve up DHCP for client devices.

     

    We have something like 250+ locations and each location will have a network device (same device at each location) on the network.

    The network device will sit on the same VLAN as my 'D, L3' subnet.

     

    Is there any way to somehow DHCP reserve for it? I know we can reserve a fixed amount of IP space before and after the range but if  I want my device to end on .10 for each subnet since I dont know which subnet will be assigned to which location?

     

    any ideas?

    ok the way to do this is you start your D,L3 subnet one subnet behind the subnet you want.

    if you want your end device to be 192.168.3.10 then your D,L3 subnet should start at 192.168.2.0 on your switch. for some reason it adds +1.
