Configure multiple dhcp bindings

I have a problem configuring a dhcp pool on a 3750 switch.

I would like to input on the dhcp scope address reservations for 20 ip phones, so that the phones get always the same ip address.

The problem is that it only let me input only one address binding.

Example of the configuration:

Ip dhcp pool test

network 192.168.10.0 255.255.255.0

import all

option 150 ip:x.x.x.x

host 192.169.10.1

hardware-address 11aa.22bb.33cc

If I input a second host and the mac-address of that host, the first one is deleted.

I do not want to create 20 dhcp different scopes for 20 phones.

Can you please advice...

Thank you in advance...

The only way you will do this is by extended the DHCP lease to never expire. If ALL phones need the same specific address then you must define 20 pools, or extend the DHCP lease.

Thanks for your fast reply.

I already did this but I was wandering if there is any other way to implement this.

Thanks a lot anyway.

No using a Cisco device as the DHCP server. If you have a Windows Server acting as the DHCP server you can.
