dhcp service

I currently have a Catalyst 2960S with IP Base software and I'd like to implement DHCP server and voice vlan. Will the 2960S support those features? I tried the switchport voice vlan command and it took it. So I assume that it is doing voice vlan. But not sure about dhcp. With DHCP, do you have to use layer 3 switch or a layer 2 switch is fine?

A 2960S series switch can be used as a DHCP server, just needs to be configured.

Here's a sample DHCP Pool config:

ip dhcp pool myfirstdhcppool
domain-name myfirstdomain.net
lease 4

You can also configure a voice VLAN on the switch interface as well.

Here's a sample interface config:

interface FastEthernet0/1
 switchport access vlan 100
 switchport voice vlan 150 <- This will enable a Voice auxiliary VLAN for the interface
 switchport port-security maximum 4
 switchport port-security mac-address sticky
 spanning-tree portfast
 spanning-tree bpduguard enable

Do you need any QoS to prioritize the voice in fa0/1?
Catalyst 2960S supports voice vlan an dhcp and above example is good. So please try with above example.
Depends on the size of the deployment. From the sounds of it, based on wanting to use a 2960 as a DHCP server you should be fine without QoS.

Plus, QoS really only helps if its configured on all devices that traffic flows on.

do not forget to enable DHCP in your router.
