Hope everybody having good day 

i have an issue when i try to add dhcp vlan pool 

i wan t two add two dhcp pool for two van at my controller when i add one of them i got the below error

Failed to add pool X which has 4094 addresses. Maximum addresses configurable is 4096 in the config path.
Currently configured are 253 addresses. You may want to exclude unused address ranges.

Thank you in advance for the answers

Controller DHCP servers have a limit to the size of their leases:

Thanks for replay 

but this only support 7005/7008/7010 series , but my controller is 7205 which is not on the list 

so when in try run ip dhcp increase-lease-limit  it say this command is not supporting on this platform 

thanks 

Do you have a screenshot of what you were trying to do when you got the error and what version of ArubaOS you are running?

I am version 8.6.0.1

once i run the folloing command 

ip dhcp pool vlan_90
default-router 192.168.144.1
domain-name aruba.local
network 192.168.144.0 255.255.240.0

 i got the error below 

Failed to add pool vlan_90 which has 4094 addresses. Maximum addresses configurable is 4096 in the config path.
Currently configured are 506 addresses. You may want to exclude unused address ranges.

as well i can add dhcp pool with subnet 255.255.255.0 with no issue 

thanks

It sounds like your limit is 4096 addresses on that platform.  I would use an external dhcp server if you want to provide more addresses.

Thanks
