INFOBLOX DHCP Scope

[hebegb41]

All, We are trying to set up a DHCP scope on our network using INFOBLOX DHCP server using i2004 phones on POE blades on a CIsco 45XX switch with a voice VLAN and a native VLAN. Right now we have 2 strings set up:

1) Option 128 with string Nortel-i2004-A,10.xxx.xx.x:4100,1,5:10.xxx.xx.x:4100,1,5.

2) Option 191 VLAN-A:130

our VLAN is set as 130 and I have tried every possible config on the phones. No matter what I try the phones never get a VALN 130 address from DHCP unless I hard code it on the phones. They can get a native VLAN address for the PC but not a voice VLAN address.

I pulled the DHCP scope info from the Nortel Doc for a windows server 2003 format and modified it for INFOBLOX since I cannot find any specific layouts for INFLOBLOX.

Here is my VLAN config in the Cisco:
interface vlan 130

description VoIP SWx.2xIDF

ip address 10.xxx.130.2 255.255.255.0

ip helper-address 10.xxx.55.53

no ip redirects

no ip unreachables

ip pim dense-mode

standby 1 ip 10.xxx.130.1

standby 1 priority 105

standby 1 preempt

Here is my port configs on the Cisco:

interface FastEthernet {interface number}

description "port number"

power inline static max 7000

switchport trunk encapsulation dot1q

switchport trunk native vlan 41

switchport trunk allowed vlan 41,130

switchport mode trunk

qos trust dscp

What we would like to do is have the i2004's basically auto discover the voice VLAN and boot. I have tried every config possible on the phones to get them to boot off of VLAN 130 w/o hard coding the VLAN on the phones. What I am missing or doing wrong???

Greatly appreciate the advice

From what I know I believe you need a TFTP server to 'push' the config to the phones. By config I am talking about S1, S2, DHCP, VLAN, PC port ON, etc.
Unfortunately the Nortel phones don't work as slick as the Cisco 79xx series where they auto-register with their MAC Then you just go into the Cisco phone web page and update the config with the name/number, etc.
We have always setup the Nortel phones manually (enter all the config info).

Do you have the Option 191 and 128 on your native VLAN DHCP scope?

We use a combination of DHCP and TFTP to auto configure the phones. Works slick we don't have to manually configure anything.

I'm not sure that I am saying this right, but I think option 191 has to be a scope in the first dhcp choice (the same one that pc's use). It assigns the vlan to the phone and than it looks at the vlan dhcp scope for the rest of the info.

GuyCable2 and Wane47, Is there anyway I could get a copy of config for both the TFTP server and scope from you guys. We are close but just can't seem to get it nailed down. BTW we are a CS1k with rls 5.5. We have tried the options 128 and 191 on the native VLAN and still no IP discovery. Good advice though and I really appreciate it.

2001/2002/2004 do not support TFTP config files but do support the Nortel-i2004-B dhcp infoblock.

Have you tried the last (0604DCN) version of firmware for the 2004 to see if it makes a difference?

 

[hebegb41]

gwebster, I do have the 0604DCN firmware on the 2004's and no difference. I am confused on your first sentence.
My string in the infoblox server is nortel-i2004-A...not B....should I try the B string??

Still hoping that guycable2 and Wane47 can provide a copy of the config. We are looking for that auto discovery and I cant believe Nortel on Cisco cant do it. There has to be a way...

 

[guycable2]

We have cisco for our data and your config looks the same as ours. I will see if I can post our config on Monday. We use 1100 series phones exclusively so our TFTP file won't help.
