How to setup IP HELPER ADDRESS or GIADDR
Posted on 2007-10-04
I am setting up a voip solution into my netwrok. Currently I have 2 switch cisco 2950 and one router cisco . one server that has DHCP. I just bought a new switch from DELL 3448 it has POE and VLAN. I was able to setup 2 VLAN:
VLAN 1 for my computers and VLAN 5 for my phone.
my first scope on my DHCP is : 192.168.1.50--> 125
I want to create a second scope : 192.168.2.50 -->125
Now my problem is how do I tell the DHCP server to give IPs from the second scope to my phones only (VLAN 5)?
I kind of understand the concept of ip helper , but how to set it up? or is it better to use GIADDR? or something else.
