Hi,
need assistance here. Have anyone encounter issue of setting up IPPhones with static Addressing on data VLAN?
Here are the set up on my L3 switch:
Vlan Assignment:
Vlan 420 - dhcp (data)
Vlan 120 - dhcp (voice)
Vlan 440 - static (data)
Port configuration
set-up1(both dchp):
interface FastE 0/1
switchport access vlan 420
switchport mode access
switchport voice vlan 120
Set-up2(Static on data and dhcp on phone):
interface fastE 0/2
switchport access vlan 440
switchport mode access
switchport voice vlan 120
DHCP Scope:
ip dhcp pool for_vlan420
network 10.150.2.0 255.255.255.0
default-router 10.150.2.1
domain-name newbies.com
option 242 ascii "L2Q=1,L2QVLAN=120"
dns-server A.B.C.D
(observation: IPPhone and Notebook able to grab IP)
ip dhcp pool Static_vlan440
host 10.150.3.19 255.255.255.128
client-identifier 0100.xxxx.xxxx.xx
default-router 10.150.3.1
domain-name newbies.com
option 242 ascii "L2Q=1,L2QVLAN=120"
dns-server A.B.C.D
(observation: Notebook only grabs the IP and IPPhone cannot)
Thanks in advance ;)

Hi,
you need option 150 with the IP of CM in dhcp pools. Without that, IP phones will not accept DHCP offer.
Hope this helps, please rate post if it does!
