Voice Vlan

[Sadam]

Hi thanks advance 

in my network everything working fine. I’m using Cisco 3850 for core. 2960 for access layers. IP phone avaya IP office 500. 

           I need to push the data Vlan form the IP phone. How I can do it. 

Data vlan 200

IPphone Vlan 10

Thanks.

Let me give some steps  to work :

1. You need to have DHCP Server with different IP address or same IP address different netmask.

2. create a Voice and Data VLAN

interface vlan 200

ip address x.x.x.x

ip helper-address z.z.z.z

interface vlan 10

ip address y.y.y.y

ip helper-address z.z.z.z

3. In DHCP Server configure Option 

4. apply the vlan config to interface as example :

interface FastEthernet1/0/2
switchport access vlan 200
switchport mode access
switchport voice vlan 10

more details found here in this document.

Hi Frnds,

Sorry for the delay reply.

interface Vlan10
ip address 192.168.10.1 255.255.248.0
ip helper-address 192.168.10.254

interface Vlan200
ip address 10.200.0.1 255.255.240.0
ip helper-address 172.168.8.3
ip pim dense-mode

interface FastEthernet1/0/2
switchport access vlan 200
switchport mode access
switchport voice vlan 10

i did the config before like above at that time i can get the dhcp from vlan 200 but for vlan 10 ip phone not getting the dhcp ip.

thanks advance.

have you setup a DHCP option ?

http://blog.router-switch.com/2013/03/dhcp-option-150-dhcp-option-66/

interface Vlan10
ip address 192.168.10.1 255.255.248.0
ip helper-address 192.168.10.254     <---- how come you have 2 different Helper address here 

interface Vlan200
ip address 10.200.0.1 255.255.240.0
ip helper-address 172.168.8.3  <---- how come you have 2 different Helper address here

Do you have 2 DHCP Server for voice and Data ?

Hi thanks for guidance. 

We have two different dhcp for voice and data. 

For the voice dhcp ip pool from the IP PABX. 

Data have separate dhcp from the server Vlan.
