More than one DHCP pool with Aruba Instant 6.2.1.0-3.3.02

[ Edited ]

 

I have an IAP 93 running 6.2.1.0-3.3.02 and I would like to set it up as a DHCP server.

 

I know I can set up the main DHCP Server pool on System > DHCP

But I would like one SSID to be assigned a range of IP address, and another one a different range. For example:

 

- SSID 1 should use DHCP Scope 10.103.1.0/24

- SSID 2 should use DHCP Scope 10.103.2.0/24

 

 

I've tried using the More > DHCP Server and tried creating both Distributed Layer 3 and Other modes, assigning the pool to a vlan and then selecting the vlan on the SSID configuration, but I haven't been successful,

What would be the procedure for setting up more than one DHCP pool and then assigning it to an SSID?

That is not suported.  The More --> DHCP settings have to do with IAP + VPN functionality.  You are limited to one scope and that scope is ONLY assigned to SSIDs set to "Virtual Controller Assigned" for IP addressing in the VLAN tab settings.

 

I recommend an external DHCP server for your scenario.  An Aruba switch (with a ton of IAP integration like auto VLAN config and Rogue AP Wired correlation) can also function as a DHCP server.

Thanks Seth! We are going to use an external DHCP server instead.

by defining a LOCAL scope under DHCP servers, you can now specific a specific block if addresses to assing on a per SSID basis. Note that your VLAN assignment needs to be NETWORK when establishing the SSID parametres.

Put up a simple IAP Guest Network to denote that we can define local DHCP pools, have the VC assign them and tag to the SSID in question.

 

wlan ssid-profile IAP-Guest

enable

index 0

type guest

essid IAP-Guest

opmode opensystem

max-authentication-failures 0

vlan 15,16

auth-server InternalServer

rf-band all

captive-portal internal

dtim-period 1

inactivity-timeout 1000

broadcast-filter none

dmo-channel-utilization-threshold 90

local-probe-req-thresh 0

max-clients-threshold 64

 

 

ip dhcp IAP-Pool

server-type Local

server-vlan 15

subnet 192.168.15.0

subnet-mask 255.255.255.0

 

ip dhcp IAP-Pool2

server-type Local

server-vlan 16

subnet 192.168.16.0

subnet-mask 255.255.255.0

What is the maximum dhcp scope supported?

Is it 512 addresses on IAP? (Y/N) ___
