DHCP reservation

good evening everyone
I created my dhcp pools, but now I have about twenty devices to which I have to set a fixed ip address, via reservation.

The M4100 allows the creation of a maximum of 16 pools, I have read in some posts that there is the possibility to create the reservation via CLI but I have not found any documentation about it; can anyone tell me where I find it?

Thanks in advance

Hi attilay2k

Sorry to be the messenger for the news below

You are right, one static binding per DHCP pool, and maximum number of DHCP pools in M4100 is 16.

So we can only get one DHCP pool for your dynamic addresses and 15 static binding's using the pools 2-16.

For your information, the maximum number of DHCP pools can be found in the Platform Constants section of the Tech Specs in the M4100 datasheet.

The M4300 switches offer 256 pools and would help you.

Maybe you could consider the new M4250 switches, they also offer 256 pools.

Datasheet

There is model called M4250-10G2F-PoE+ (GSM4212P-100NAS in the US) with 10x1G ports and 2xSFP uplinks

I hope this helps!

Regards,

  thanks JohnC_V
  
  I had already seen this post, but it is not clear to me if by acting in this way I can exceed the limit of 16 pools (i.e. if I can add more clients to the pool_manual) or if that limitation remains

    attilay2k,
    
    The limitation remains even though you use CLI to have a DHCP Reservation. This is a device limitation and not just a GUI limitation.
    
    Hope it helps :)
