Meraki Fixed ip assignment

[Vishal07]

Hi All,

Can we achieve fixed ip assignment to mac address reservation to client machine without configuring reserved ip ranges in our dhcp server configure in Meraki Mx.  Pls find attach snapshot for you reference.

[Brash]

Yes, that configuration is valid. You're essentially configuration DHCP reservations

"Fixed IP assignments - Allows specific MAC addresses to always be assigned the same IP address. These addresses will not be allocated to other devices on the network."

Without configuring reserved ip ranges ?

You could use DHCP relay instead, but you'd still need to create reservations on whichever DHCP server you relay to.   Your other alternative is statically configuring IP on the client itself.

Finally, you could use the API to do this, via fixedIpAssignments with this endpoint:  https://developer.cisco.com/meraki/api-v1/update-network-appliance-vlan/

That is basically doing what you've shown in the UI, via a different tool.

Yes, fixed IP assignments are 1 MAC address to 1 IP, whereas reserved IP ranges are the range of IP addresses that you don't want DHCP to issue.  This would cover IP addresses that are statically assigned to a client in that subnet.  The two are totally separate and you can have either without the other.

So with fixed ip assignment my client gets the fix ip against their mac address without configuring reserved ip ranges ?

[cmr]

Yes exactly that.

Reserved IP is taking those IP addresses out of the DHCP scope.
