IP Office DHCP IP phones 1

[thrtnastrx]

I can't get my Win2K3 DHCP server to work properly.

Data VLAN = 192.168.173.0/24
Option 176 = L2Q=1,L2QVLAN=1

When the phone boots it shows VLAN ID=1 in the display then reboots.

Voice VLAN = 192.168.174.0/24
Option 176 = MCIPADD=192.168.174.48,MCPORT=1719,TFTPSRVR=192.168.173.51

The phone displays:

“No file server address” “No call server address”

If I manually assign the phones the IP address 192.168.174.xx they work fine. I have searched the forum and found some help but I seem to be missing one critical piece of information.

do you have the vlan settings for 176 in the scope also as you seem to mention it twice above.

you also don't need mcport settings, this is entered by default

I am not sure if this would help but is your switch configured to accept traffic on both VLAN 1 and VLAN 2. It sounds like the switch does not know where to send the traffic and is only configured on your primary VLAN.

I am not 100% sure but your DHCP server looks okay based on what you've shown me.

Shouldn't the TFTP server be 192.168.174.x not 173.x ie in the Voice VLAN. Is the IPO and the TFTP server in the Voice VLAN tagged by the n/w switches??

what kind of switches are they. i have seen where you need DHCP helper statements on the switches.

jamie77 you should use this [-quote-] and [-/quote-] but then without the - in between

How is your dhcp server set up?

Does it have two nic's - one sat in both subnets

If not then you need to enable bootp relay over the vlans so that the dhcp server can server both subnets.

Most L3 switches / routers will do this but you have to enable it.

As per puregold i am working on the very same type of configuration at present

I copied a document from Avaya site which goes thru the complete setup using HP Procurve Layer 2 switches.

Shows 2 NIC cards in DHCP server one for data lan and one for voice lan.

Your original post shows the TFTP server address as being on a different subnet. I believe it needs to be on the same subnet as TFTP is like DHCP a protocol that does not transverse between subnets.

 

[puregold]

You can have a tftp server on a different subnet to the IP phones no problem.

As long as you are relaying your dhcp there should be no problem.

Do you have HP 2626 Switches?

If your using 2 scopes on your DHCP server you have to add a route;

Start > Run > typ CMD press enter.

route ADD 192.168.174.0 MASK 255.255.255.0 192.168.173.xxx /p

(where xxx is your routing Switch which can route from data VLAN to the Voice VLAN)

In one off your switches you have to set VLAN Routing on.
