Hi Sungjin,

Apologies but I don't think we publish this information.

However I have tried setting up a huge DHCP pool and I get an error (please see screenshot attached), which indicates the maximimum pool size is 1,000 addresses.

I hope that helps!
Darrel.

Even 1000 hosts in same VLAN is a usually a bad idea. Exception is when full client isolation is enabled.

Anyway, exactly to address big number of clients on the same SSID SmartZone supports VLAN pooling -- so multiple VLANs can be attached to the same SSID. This feature is needed in big public venues mostly (stadiums, etc.), and you just use as much VLANs as you need -- 2/4/8/16 etc.

Hope it helps.

Thanks.

My client created a DHCP profile and then created DHCP pool

example)

DP-DHCP-Pool1 10.200.0.0/16

DP-DHCP-Pool2 10.202.0.0/16

DP-DHCP-Pool3 10.204.0.0/16

DP-DHCP-Pool4 10.210.0.0/16

DP-DHCP-Pool5 10.212.0.0/16

and add one more subnet 10.214.0.0/16

but popup below

You mean

example)

192.168.0.0/24 : VLAN 2

192.168.1.0/24 : VLAN 3

192.168.2.0/24 : VLAN 4

192.168.3.0/24 : VLAN 5

192.168.15.0/24 : VLAN 17

use VLAN pooling

Each VLAN pool can contain up to 16 VLANs, and a maximum of 64 VLAN pools can be created.

but my client design maximum 300,000 device dhcp

DP-Profile

DP-DHCP-Pool1 10.200.0.0/16 : VLAN 2

DP-DHCP-Pool2 10.202.0.0/16 : VLAN 3

DP-DHCP-Pool3 10.204.0.0/16 : VLAN 4

DP-DHCP-Pool4 10.210.0.0/16 : VALN 5

DP-DHCP-Pool5 10.212.0.0/16 : VLAN 6

ssid 1 : vlan pooling ( vlan 2~6 )

is this right?

300 000 clients?! It's something ... For how many APs? Can't imagine real project, which supports that much clients. I have really seen something only on scale of ~10 000 simultaneous users on the same system, and thought this is quit a lot, but this is different scale and really a lot more!

Only case I can imagine for that is some service provider with many thousands of APs in different locations, in this case you probably can leave with such big subnets, using traffic isolation.

I suggest you discuss with Ruckus development what is the best way to handle that, as it is definitely not a typical situation, and they are best positioned to recommend the best solution for such project.

Hope it helps,

It is unpredictable how many concurrent users there will be, but expect many devices to be connected. ( could be more or less )

So we are investigating the limitations of each element to design the configuration.
