OPTION 150 in two VOICE HDCP POOL IN SAME SWITCH

Hi

I am having two sides.  Side A is getting IP address via DHCP Pool (Voice and Data).  Side A SW is direct trunk with Core SW. Side A is working Fine.

Side A configuration is bellow

ip dhcp excluded-address 10.10.10.193

ip dhcp excluded-address 10.10.20.193

!

ip dhcp pool data

   network 10.10.10.192 255.255.255.192

   default-router 10.10.10.193

!

ip dhcp pool voice

   network 10.10.20.192 255.255.255.192

   option 150 ip 10.10.30.1

   default-router 10.10.20.193

!

Interface Vlan10

Description **** For Data VLAN ****

IP address 10.10.10.193 255.255.255.192

!

Interface VLAN20

Description ****FOR VOICE VLAN *****

IP address 10.10.10.193 255.255.255.192

Now we are going to Add Side B. We want to add some phone on Side B. Side B SW will be  direct trunk with Core SW.

What should I do? If I create another Voice DHCP pool will it work for option 150.??

I am really Confused….? How to configure it.

Hi Sultan,

If you want the second switch to take the ip addresses from the Side A pools, then you just need to configure the ip helper statements on the respective interface vlans pointing towards the side A.

Configuring a Cisco router to forward BootP or  DHCP requests is simple - configure an IP helper-address pointing to the  DHCP/BootP server, or pointing to the subnet broadcast address of the  network the server is on.

You can look at the ip helper configuration from the following configuration link:
