DHCP - One host multiple IPs

Apr 23, 2008 5 Replies

Dear Folks,



is it possible to assigne a host (one mac address) more then one static IP. The reason is, that a NAS is not abel to configure with a static IP. This NAS has 2 NICs but only one MAC Address and I'd like to assign this NAS 2 static IPs.



My DHCP "Server" is a Cisco Catalyst 6506 E.



Thanks



Robert


a NAS box that can't have a static ip?

I'm really curious as to what the mfg is on that..

Should be able to get this working if you put the 2 NICs into different VLANs.

How can it have 2 NICs and only 1 MAC address? Surely each NIC will have its own address as each NIC controller will have it embedded on the chip.

More to the point why does it have 2 NICs, from the documentation what is the purpose of the second NIC? and as someone else has commented what is the manufacturer/model of the NAS.

Having one MAC address for the box is a perfectly valid configuration, and is in fact how for instance Sun workstations/servers *used to be* configured. It will work fine as long as the NICs are on different Ethernet segments, and the MAC addresses of the different segments are kept separated at the switch (or whatever) where they are connected. It is no longer very common.
