Dell N Series – No Free IP Address To Offer In Pool Blog Networking October 13, 2020 jasonkuehl
At this site we installed a new Dell N Series core replacing a bunch of old junk. As I’m doing the new build I moved all the DHCP requests to the core and away from windows which took care of all the DHCP requests. This was on a off day with no one around (Duh replacing the core) and I was not really worried. After about 30 minutes my console is filling up with the below messages.
Note: Yes it’s VLAN1 it predates me and is waaay too messy to remove in a weekend.
Error “No Free IP Address To Offer in pool VLAN1”
Start freaking out Did I fill the pool already? How can that be?

Everything looks fine, and the pool is not even close to full… To the Logs!

I’ve seen this before in Cisco where a device holds onto a DHCP address. You need to track down the MAC and give the device a reboot. After the reboot (of the device) these errors should go away.
