How can I tell which interfaces have a static ip vs dynamic assigned ip

we currently have 3 vlans for wired devices, one of them is getting low on available IP address to assign, so I plan to move over 30 of the interfaces to one of the newer vlans with more available IP's. I not sure which interfaces have dynamically assigned IP's and which have statically assigned IP's. what would be the more efficient way to determine this?

Hi @EdwardClark9818 

 

Maybe this method will help you:

1-Review the addresses delivered for the DHCP server

2-Filter the addresses that correspond to the pool of the current vlan.

With the IPs delivered, you can know the devices (MAC address) that get DHCP.

 

3-On the switch, check to which port these MACs are connected.
Now you know which connected devices got their IP by DHCP.

 

Regards

 

ok thanks for the suggestion, I'll try and see how close this gets me.
