Dell N3048 DHCP pool limit
Hi everyone,
I have 4 Dell N3048 switches, configured in 2 stacks of 2 switches each one. All of them have 6.1.2.4 firmware software. They offer connectivity to a BigData cluster, eah stack for a rack of servers. I tried to configure DHCP server on the Dell switches in order to provide a static IP address to the management interface of the servers in the rack.
I managed without problems to configure the static DHCP pools for the first 16 server, but I am unable to do so for a further one (I have 20 servers each rack). When I try to create a new DHCP pool I get:
#configure
#ip dhcp pool NewPool
Could not create DHCP pool.
It seems that the N3048 does not allow for more than 16 DHCP pools, which is the number I already created. I could not find any hint on this limit in any documentation of the swich (CLI, UserGuide of the 6.1.2.4).
Is there such a limit?
If there is such a limit, is it possible to solve this problem in a different way? I am creating a single DHCP pool for each static IP address, which is the procedure I found in the manuals. Is is possible to have a single DHCP pool with more static IP addresses (each one reserved to a specific MAC)?
Thank you all.
Fbota.

I found only a limit on the number of leases (maximum of 256 indicated in the documentation). However the manual of Dell Force10 S2410 switch states on page 130 (www.manualslib.com/.../Dell-Force10-S2410-01-10ge-24p.html) that it supports a maximum of 256 leases and 16 pools... I thought it might be something similar with N3048 too, altough in case of static DHCP it is quite limiting (only 16 static IP configurable).
Thank you.

Hi every
I have N3024F, and create 14 pools, when DHCP lease about 210 IP
log show "No Free IP address to offer in pool Pool-v100"
so I guess N3000 maximum lease is 21x?
