MAC Address Binding in data center environment


Hello all,


I am writing to see if anyone can help me out with this.

We are setting up a data center environment network, and we are looking to bind IP addresses by MAC Address without using a DHCP pool. 

Right now, we have everything in about 20 VLANS with large ranges and IPs are being stolen, so we'd like to lock them down somehow. 

I've done a lot of reading and found commands such as client-identifier and hardware-address, but they are always used with a DHCP pool. We'd like to manually assign the IPS and then limit to them to a specific MAC address. Is this possible? Or would we need to limit everyone to their own VLAN? 

We are running a cisco Nexus 3064 Chassis with NX-OS 6.0.

This is not the best way to do it, but if the requirement is like that - you can do sticky MAC with IP address.

Hi There,


Thank you. From what I can tell, this restricts a VLAN or port to a set of defined MAC addresses? If we did it this way, we could just make a separate VLAN for each client. We know this is an option, but we're trying to find a way to limit the amount of IPS lost due to subnetting. 

Basically, we're looking to do something like:


IP --> Locked to Mac Address xxx, independent of the VLAN involved. 


Is that doable or would we need to do it via a DHCP pool?
