Maximum DHCP Leases for SDX

Hi,

I setup networks for large events and I have one coming up where I could have over 4-5000 devices on the network at any given time. It will be broken into a number of smaller subnets and VLAN’s, but I was curious if there was any specific limit to the number of DHCP leases the SDX could give out across all LAN subnets? I have used another product line and they have a hard limit of 4096 address leases.

Thanks,

Jim
