EXOS DHCP Address Limit

EXOS DHCP Address Limit

We have sometimes problems with SecureStack (B5) as local DHCP server (at branches).

As is i learned today in the GTAC KB:
SecureStack Stops Providing DHCP Addresses
There is a limit of 256 IPs per Switch ! (not per VLAN)

This can explain my problems!

Now i am looking for the limit of EXOS Switches (which maybe should an alternative there)

But Release Notes / Manual does not tell anything about this!

Does anybody know how many IP Addresses a EXOS can provide via DHCP to Client per VLAN and per entire Switch ??

Thanks.

Hello Matthias, I'm not sure about the limit.

However, I have made a quick test with 5 vlans with 250 address allocated to the switch DHCP server for each vlan and had a total of 1.250 address offered by the switch.

Since you have mentioned that a maximum worst case would be 1k address I believe 1.250 is a great number. 🙂

Hi Matthias,
I don't think there is a address number limitation in a vlan for EXOS platform, but there is a max number of dhcp server per vlan limitation.

Hi,



It would be quite difficult to arrive at an absolutely number you are speaking about, since we are considering factors that fluctuate with need.



If you would still want something concrete, i will leave it up to the experts following thread to comment.

Hi,

because any EXOS Switch should be an better replacement of existing limited B5 - a X440-G2 or X450-G2 will be the prefered HW platform.

currently we have 4 IP Subnets (Class C - max. 256 hosts) - means maximum worst case 1000 Clients.

Does this working with X440-G2 or X450-G2 ??
