Hello Cisco Experts - I'm trying to setup a new DHCP scope on my Cisco 2504 and am getting the error referenced above.  Here are the settings I am using:

WAC


I have another range setup in exactly the same way only it runs from 10.35.209.65 through 10.35.209.90.  Can anyone point me in the right direction for what I'm doing wrong?  Thanks in advance!

you specify network 10.35.208.x
but the pool you want is 10.35.209.x

is that correct ?

Yes but the subnet mask should include both ranges, it encompasses 10.35.208.1 - 10.35.223.254 though we only use the 208 and 209 ranges.

Hi,
i'm afraid you cannot set multiple scopes into the same VLAN subnet.
You need to create a separate VLAN and associate the DHCP scope to the new VLAN.
As you said, those 2 scopes you're trying with belong to the same subnet.

hope this helps
